YLR Racing

[Yow Ling]

YLR is a collection of old and young, I guess it evolved because I have a pretty big shed and collected a few bikes over the last 15 years. Team members are Jackson Cotton, Buddha, Bren and me, we are happy to take on the odd stray as well. Mostly based around buckets there are a few other bikes lying around in various states of finished.

Well the YLR team had a great day at Levels, we were a little down on numbers with just one team rider turning up with just one bike, still got about 160km of racing done.

Always good to go to a Cams meeting, they low pressure affairs with plenty of rounds.

Not too many bikes in any class , so you could run in any class you wanted on any bike, nobody gets too tense, this worked out well for Scout who was having trouble with the old RD350 she had, she temporarily joined YLR for the day and rode my bucket in P89 F1, P72, and P89 p82 F2 F3.

I had decided that I needed to push a bit harder than I had been and thought I was doing ok , Cam came over and gave me some advice "why dont you go round corners faster" well duh I thought I was, looks like plenty of room to Improve so for the rest of the rounds I worked on this, sometimes you just need to be told!

As the day was getting on a few bikes had expired and they were scratching to fill the classes we switched to all ins Scout did the p82,89 and moderns, I went out for the p72 and had a great race with agent 75 , Ashley and Stu on his triumph twin thing it was like 3 Jack russel terriers annoying a sheep, was great!

Thanks to Neil Lockie and the rest of the Cams guys for putting on this meet

I cant claim any fame for this bike, Its ex John Hepburn and its kinda cool

Lucky little bugger. All I got for my 10th birthday was a lump of coal, and I had to share it with my brother.

Hope he goes well, he's certainly in for a truckload of fun.

Did you get that off Barry Gurdler ?
If so, built by Ned Kelly in Timaru. Hep did some early development riding for Ned but never owned it as far as I know. Ned's still around and tinkering so would probably help with information if needed.

Like the classic Fiat 500. Well worth a restoration that. :)

One's a track bike (still in system, just no lights at mo) One will get a RZ350 engine (2XT model with 2.75 and 3.5 wheels) and there is a spare thats undecided at the mo. Probably a bucket.

Better finish the 2KR FZR/TF125 one 1st

[Yow Ling]

YLR was out in full force today. Christchurch might be a bit rooted at the moment but has a wicked track and tons of opportunities to use it.
The team consisted of Buddha ,Jackson and Olly Cotton, Damo, and me. Because we had a garage there were a few others welcomed into the shade.
The bikes were 3 FXRs, an RS50, KR150 and my old TZ250

It was Jacksons big day, his first fang round Ruapuna on his Aprilia RS50, managed to keep it on its tyres all day. Good one Jack!

buckets was mixed with Prolites and Streetstock so the grid had about 40 bikes charging into turn 1. Works Ok I think the best aspect is Buckets give some prolites and ss a hurryup,

Today I took the Sacred Cow to the track, its a 1981 TZ250H, Ive had it for about 5 years and fixed the motor, didnt really want to ride it because it only had racepattern and my brain doesnt have enough space to be able to deal with that especially under pressure, so this week I made a new rearset to run road pattern.
I went out in practice on it , its quite a leap from anything Ive ever ridden no power under 8k, 1st gear is verrry tall, when the power comes in its mentaland it pretty much all done by 10k, I did a few laps but decided to come in early as it had a few issues, like the rear axle not being done up! I think I cant have pressed the bearings in properly and after a few laps had seated properly, just kind of unnerving when the back wheel steps out every gear change.

now you know you have to build a bigger better bike for him :shutup:

Poor Robert droped his bike twice today
first time in practice (slicks in the wet at Mt Wellington:facepalm:) broke the foot peg and thought that was him for the day. gigglebuton lent him a new rearset and he was off
On the last race he ran off the track hit a big hole and threw it all away. Got the bike going and ran around to the start line to grid up. Found that he didn't have much frount brake and nearly hit everyone. He had smacked the bango? bolt and losened it leaking brake fluid from the master. That was the end of the day for him. He managed a 2nd in the last prelim (out of 4 bikes. one pulled out and another stoped going) and a 5th place in the race. He is a bit sore but smiling from ear to ear

[Yow Ling]

I think we have 3 years to sort out a bigger bike, actually we already have a few spares.
Bad Luck Robert, I dont know how you Aucklanders put up with so much wet riding.
I think we have racing of some sort every weekend for the next month or 6 weeks, dry and sunny Im hoping, although Buddha scored me a spare set of rims for my bucket , just in case.

I thought there was three, as Cully was having lunch, my bike really didn't feel like playing, and Nathanael decided against going out in the 2nd prelim.
I'm glad I managed to avoid Robert all 3 times I've been behind him when he's crashed, and dread the day when I've got nowhere to go.
XL100's obviously need to be charged up for each day's riding, as that looks to be what was wrong with #65.

Ah well, will have the kids beating me again come November/December.

It really is cool to see the young ones coming along. Little Robert has lost some confidence, but it'll come back (you need to build him his XL100).

Oh, Yow-Ling, when your boy's finished with the RS50, I know a good home for it lol :)

Husaberg does indeed like it
I toe started my berg with my V6 Hilux one day 4 gear 100m still skidding Maybe I should have used the decomp?
Mine left foot kick too for added fun. Still way easier to start than the CR500 is.
My old one was impossible to start hot, wait teen minutes and it was just possible. From cold was easy.
The best thing about the husaberg is the induction noise it sounds like it is going to inhale your privates.

Great collection though.

[F5 Dave]

what a waste of an RZ500 seat cowling bodged onto a 1KT tail end. But then with a dirty diesel in it.

[Yow Ling]

It came that way , my concience is clear.
RZ500 is actually a bit overrated

[F5 Dave]

yeah, you can lose a smeg load of weight off them. They were restricted by adding stuff. The lower pipes alone are about twice the weight of RZ350 ones.

[husaberg]

Why Was it put down?
Or was it pipped at the post by another fitter younger thread?
Was the mare though i me posting another er post enough to kill it off.
Because seems a shame cause Yow has a nice collection of steeds in the YLR stable.

[Yow Ling]

YLR thread has come back, the ESE thread has gone viral, #6 thread is just that the #6 thread. So here we are again

This weekend is a bit of an engineering one, my goal is to bore some crankwebs to take a 22mm pin instead of the old 19mm one. Sounds easy so far.

the first step was to tram the milling machine, this is so the hole I bore is exactly straight that took me about 45 minutes and I havnt even done any thing usefull yet.

Now that the mill is square I clamp down a crank web on some parallels and using a dial gauge centre the hole with the spindle, another 20min.

This all has to be done right or I will end up with a crank I wont be able to align, will vibrate , steal power and shit itself when it shouldnt.

Ok so now I start boring the hole, not going perfectly though as there is a bit of chatter, the cutter Im using is a bit long and skinny , the crank is pretty tough and maybe a thousand other factors are causing problems, the cuts are pretty light around 0.2mm, I try a different cutter much sturdier one, things improve but still not happy, I think Il visit the tool shop on monday and see what they have thats better
any suggestions?

[crazy man]

slow the machine down if you have chatter

[Yow Ling]

slow the machine down if you have chatter

thanks crazy

[husaberg]

I guess it is a Suzuki GP crank but why are you going to 22mm? Is there no 20mm ones that would suit?

Also please some more Honda's on the thread?:devil2:

You meet the nicest people on a Honda.
One of the other threads was ok but they kept cramming it full of Yamaha's (will my Yamaha be linished for Tihape):rolleyes:

[crazy man]

the other thing l would do is make a lapping tool up for finshing it of

[crazy man]

sorry its a crapy pic . start of with a shaft with a very light tapper on it you have to buy a remmer with the same taper . the cast iron peice is taper reemed inside with a cut to alowe to open when to parts are pushed together run some light groves in the cast iron to alow for sluge to get in . the is a cuting compound to be used and diamond past. you maybe able to just buy one. hope it makes sence262895

[F5 Dave]

S'funny I made my suzuki 50 from a 17 to a 19 BE to use those lovely Yamaha parts.

[Yow Ling]

Thanks crazy for your advice, set me in the right direction.

Made some progress, I wasnt happy with the boring tool so I made a tool holder from an old lathe boring bar that takes 3/16" HSS, ground up a tool and had another stab, reground it a couple of times untill I was getting a nice finish in the bore. Thought I better check the size and it was 22.2 mm well thats a bit over, never mind this is just a test crank, big mistakes are welcome!

Went to Cliff Bond and got some cast iron to make a Lap with and while I was there got some CI to make a sleeve with. Funny place going out the back is like stepping back in time, all old machines most older than me by a good margin. While I was there an old guy brought a Model A piston in for rings, $95 for a set for 4 pistons, then another old guy came in with some old sidevalve bike barrel he needed 1 extra ring because he broke one. Cool place, no EFTPOS

Ferry Road, ChCh where they've been since WW2....

Suppliers of rings for damm near anything too - they have a private online catalogue which enables them to find rings if you ring up and quote a bore size and ring widths....very useful. one example...Nissan LD28 rings for a Benelli 650 twin. Better than OE - and cheaper.

Neat
i can remember the first time i seen (Lindsay Williamson) I think it was starting Blackadder (Mcintosh Egli XR1000) starting with the old Vehicle powered version.
It used to take 4 people.
One to work the ute, one for the bike and 2 big Harley type lads to hold it down.
It would probably take 6 harley types lads now (as they are all accountants/lawyers and such like.)

How times have changed.

Anyone ever tried to use a rattlegun of the flywheel?
I seem to remember Young Burt used to use a car startermotor with handles direct to the mainshaft F1 style.

Yes Koba with this method, you would put it in neutral first:msn-wink:

[F5 Dave]

try looking at Kart starters. Wheel ones are way easier for a bike.

[husaberg]

wheel is easier than? surely just plug into flywheel and go with clutch in?

Yeah seen the kart starters before.
Yes i have a few car starters plus a very powerful 12v Chainsaw motor
But i do also have a Rattlegun plus a large reservoir. Which is a lot more portable and part of the kit anyway.
I might give it a go anyway for the bucket. Not that little 2 strokes are that hard to start.
If not i might build a proper starter as the Husaberg sure hates old fuel.

[F5 Dave]

Yeah wheel is much easier if one person. wheel it back, pull in clutch, stand on switch, let go of clutch, blip throttle, choke whatever.

With hand held device, you need extra hands if it doesn't just fire up. My 50 can be started by spinning the rear wheel on the stand. Sometimes, but often it needs more.


I didn't buy a mate's 256 Rotax GP bike as it was a pig to start. Actually it was quite easy, but being a disc valve in a reasonable state of tune, it would start quite easily if you hadn't flooded it & had someone to help push.

By yourself it 'may' start up. If it didn't you'd flood it & it would never start until you got someone to help push for a bit & by that time you'd missed the line up or you were totally breathless.

I realised that if I was doing Bears events I'd often never have people travelling with me to help me starting. Never thought of (or saw) this sort of solution till many years later. the car on rollers option still needed more people & fraught with danger.

Ill take some photos today, its just built from scrap, the starter is from a toyota diesel, the rollers are some steampipe, DC used boat rollers but I was too miserable for that, use whatever sprockets you have

[F5 Dave]

Yeah the 50 has quite high compression, but of course tiny cylinder & mush lower gearing. . .actually that may work against it, maybe I should try start it in 3rd. Either way it is 1/2 piston port so is possible to load up & you really need to grab the throttle straight away to get it to catch. Much easier just to walk it forward & it starts.

The KV100 (the original Joe) was a bit of a sometimes starter if you weren't committed.

[Gigglebutton]

Thanks Mike. It looks to simple. I thought there was a lot more to them for sme dumb reason.
Trikes as well Henk. Dont you think your racing enough classes :D

[Yow Ling]

When I finally got to work today , there was a little flat package waiting. Didnt even need to open it I knew what it was , my Wobbly pipe.
Got it home and admired it, rolled a few test cones and welded them up, was using lots of restraint not to touch the wobbly ones, I dont weld for a job so it usually takes me a bit to sus out the serttings on the welder so I donrt blow big holes in things. Any way feeling better about the welding, maybe do another 10 or 15 before I go near the real thing.

After dinner I went out to the shed, bit miserable out there tonight, so i started rolling a few sections of the wobbly pipe, I have a set of small slip rolls which will do right up till the last cone, because the exit to the stinger is smaller than the rolls Ill need to think about that one a bit more.

In the picture is the first few sections of the Wobbly 1 and the exhaust nozzle

At the moment all I have is a dummy engine, that will keep me happy for a wee while, but yea starting to get a bit exciting.

While looking at pipes on the net I found this , Ill just post it because its kinda cool, I think honda had problems with shit falling into the engine with theirs, but looks cool http://thekneeslider.com/archives/2009/04/24/xj500t-jaybuilt-kawasaki-500-bellytank-triple/

Looks cool but....:msn-wink:
Honda problem was it was a piece of Poo to ride.
Honda pushed the weight way too low.
I am not suggesting it is a bad idea but.

If it is too low it literally falls into corners but it is extremely hard to pick up again.
Some bikes which are criticised for having a top heavy feeling, actually have a low slung weight distribution.
The weight transfer is also supposedly effected as well if the weight is to low.
Also the mechanics hated it as it was a bitch to work on with hot pipes in awkward places.

The Honda was all wrong they only realised this once Gardners motor home (with mirror windows)was used to get a lot of Pics of the RGV when the Suzuki garage was inadvertently left open. According to Gardner they were there for hours supposedly took rolls of pictures and blew them all up.

Afterwards they said "oh we kind of went on the wrong path there".

Any Honda four until about 91 was a bit of a dog handling wise.
Lawson (89)won a World Championship with the steering damper set to full and wrestling with it.
Wayne (87) probably didn't care if it handled as long as it was a rocketship.

[gav]

Damn, how hot is that engine going to run on an air cooled bike with those pipes?

[F5 Dave]

Yeah that pic has been around, but long debunked. Low centre of gravity is great for braking but otherwise the reason race cars are not like race bikes.

That nozzle is cool. does that (shown as up) side get bored into the cylinder?

[Yow Ling]

That nozzle is cool. does that (shown as up) side get bored into the cylinder?

It just fits inside the exhaust port, I didnt quite get it at first, needs some welding inside the port to fill a few voids

264339264340

[F5 Dave]

is there supposed to be a step? or just a smooth transition?

[Yow Ling]

Will be a smooth transition , unfortunately the most usefull material known to buckateers, Devcon , is not up to the task

[F5 Dave]

Devcon will work just fine.

unfortunately on a running engine it will only last about 1 dyno run until it flows out like treacle. is that going to be a problem?

[Yow Ling]

Made a start on the Wobbly pipe, they all rolled up and a few are welded before I ran out of argon, starting to look the part.
Having a set of slip rolls helps alot , but no help on the last cone

264501264502

[Yow Ling]

Seeing as I ran out of gas on the pipes, I spent some more time on my RD350.
It had got a bit tired and rattly after about 5 years on one set of awesome Wiseco's
In its last incarnation it had a set of RZ350 reed cages with carbon reeds, I had some Barrels I bought about 10 years ago that looked pretty nice but still had std reeds fitted. I set it up in the mill and roughed out the cavity for the reed blocks and finished it by hand, 1 down 1 to go .
I noticed on the old barrels that I had gone through the bottom wall of the reed block case and made a small hole amazingly never caused a problem, would have failed a leak test in 2 seconds flat, must have been way rich

[F5 Dave]

wow that is a super fat centre section. Looks bigger than my 500 (250) pipes. Best hope those transfers are way curved or it will over scavenge, but I bet an NSR barrel sleeved down will quite a bit. Haven't seen a 125 barrel but I have a 250 one.

Hi Dave , mine is based on the rgv250 cylinder not the Honda , I have faith in my leader, I just follow the instructions, is fat though !

Yeah Dave mine is the NSR based Motor Yowling was clever enough to start with a 50.6mm stroke engine that was freely available in NZ.
Mine from what Yoda/Obiwan. no scratch that Darth Vader says has a better crankcase so it will need less work.
Plus hopefully less filling than the RG/RGV.
The thing is with the transfers is. i think it will be easier to get the shaped Wob wants with fill than trying to cave out Air cooled 100cc cylinders to get the correct shapes as angles.
Time will tell but i are not going to be doing much racing on karts tracks and i guess neither will Yowling.
So they will need some big lungs.
plus with the engines designed for 125cc hopefully they should prove to be quite durable if a little heavier than the 100cc based engines.

[Bert]

I'm real interested to see how both of these machines develop and what the dark load has in mind with crankcases and transfer shapes.
I think the sleeved 125cc option is going to be the way forward for F4 two-strokes but there is a few unknowns especially around temperature with the larger sleeves...

What size Carbs are either of you thinking of running? Speedpro was talking around a 36mm seems rather big?? but I do wander if my 29 is a little on the small size for larger tracks.

I have a NSR250 carb (for downdraft and hondanishness)er.. not sure re the size (32mm i think) with TPS.
Plus i have a Keihin shorty 36mm but with a sleeve inserted with TPS and Solenoid in reserve. Waiting to see what will work with the chassis and the engine once they are in the same island. (Which will be hopefully soon) Carbs courtesy of TZ in a Swap.
i think to get the hp (insert big number here)with a 100cc. It will need plus 32mm anyway.TZ 30hp has the advantage of 25cc more to suck with.
But Wob is in charge of doing the numbers.

[Yow Ling]

Carb is 36mm same as Huss is talking about and same as speed pros, v force reeds and ignitech ignition, pipe is just too flash.
I'm hoping after it's going it will become the new fxr , something the cbr boys will want to have, we are lucky to have the assistance here in nz to be able to build them

if only it was more than 4 degrees outside, I may have gone to the shed to do stuff

Although we are enjoying playing with TeeZee's 125 air cooled TeeZee has been collecting parts for a sleeved 100 as a plan B that will probably go into that old NSR frame of Husaburgs. He has collected all sorts of parts including a set of Honda RS250 fully adjustable front forks.

The variety and quality of the 2-strokes and Buckets generally are getting real interesting, we just love it.

Yes; its very fortunate that there is significant assistance here in little old NZ; and most of all they offer up great information and advice for nearly nix in the scheme of things..


I also have a KX carb (same as Speedpro's); but every time I look down the intake I see future piston seizures... maybe I just need to harden-up and go for it (pipe as well).

Have you had much luck with finding a manifold that suits? or have you made your own.

It used to get to -9 at my old place. Now that used to take your breath away.
It also used to regularly hit 40 degrees in the summer with high humidly as well.

As yours is a Yamaha Bert i would try and look at some old DT and RT stuff. likely bolt on as well.
Yamaha weren't that imaginative.
The sites for Yamaha twins used to list what worked with what bolt spacing.
There are also sites that list new inlets for Banshe's and Blasters in lots of sizes.
I was thinking on setting up my old space-heater in the shed.

Did you ever manage to collate all the rod and piston stuff Brent?

I forgot that it was a yamaha... that aside I've seen the webpage that shows different reed/manifold options; but can't seem to find it now.
I know its the same reed block as the TZR250 1KT; but I'm looking for manifold that is straight (to enable the use of downdraft RGV/NSR carbs) and one that is 45 degrees that will take the larger MX carbs. was thinking that an adapter plate might be the answer if someone had come up with a simple readily available solution.

PM sent; but yes I've nearly completed the database with/and filters (sh!t load of manual entry and a lack of time); I'll post the whole thing up when finished for everyone to enjoy...:msn-wink:

[F5 Dave]

I've got a 1KT reed I think & have just got a manifold from Pete Sales which is a straight mikuni type like on a foulstroke. It will be bolted to a 10mm thick bit of ally with mount holes for reed & manifold rotated so its mount holes fit in the space. That gets my RGV, 32mm square on. I will then finish another for my KX carb which will have a angle bend in it as its a straight carb. Once (if) that is happy I'll try reducing the bend to find out what angle the carb can get away with. Its a compromise, but so is everything on an engine.

these will have a variation from 28mm to 34-36mm odd i would guess.


I can't find the site it was naughty boy then speed demon but this post has screen shots any way of the straight shots much like dave discusses
I posted a link to as British site that has all the foul stroke style inlets plus the measurements on the ESE thread ages ago Oh here.
http://www.allensperformance.co.uk/products-manifolds.html
. But as Dave says a bit of time at a wrecker if there are any left.


Right here is a copy of the TZR race kit Manual for the carb.

It does say as I alluded too earlier to block it off, but has anyone confirmed that the fueling is wrong on the bike as it is now?

If the fueling is ok now. I can't see how it will gain any HP. Unless the fueling is crap at the moment.

I should probably point out this was for this model carb what ever it is and no doubt the Crafty Japanese made a few changes during the model Run.
Maybe Hilly should give us a run-down of the carb jet specs as they are now.
I see the KR250 the Rotary Reed valve original one had similar carbs 28mm downdraft SS mikunis.
So if Hillys carb is off one of these. All bets with regards to jetting are off as the disk valve will probably have a four stroke style Emulsion tube at a guess.

I have posted the rest of the Naughty boy file as I like shiny milled billet stuff mmmm.....shiny

The ex Naughty boy racing site is renamed and is here not a bad site intersting stuff Mainly Yamaha Shame.

Thats looking good, :yes: but I am not sure about the vanes though.

Could you add a disk brake, torqe arm and load cell for constant load measurements and to slow the drum down after a run. Its something we are looking to add to ours.

I have asked before but why can't/arn't a big electric motor be used to measure HP accurately?

[Grumph]

I have asked before but why can't/arn't a big electric motor be used to measure HP accurately?

It can - but until relatively recently the electronics required to record and convert the readings were the problem.

The classic disc on a reaction frame with torque arm to load cell is very simple to build and easy to read off loadings.
I had one part built years ago but like so many projects never finished....I got instruction from a car tuner/engineer who'd built his own rolling road with the same setup. He claimed - and had the experience to prove it - that a single HQ holden disc and caliper could absorb around 120hp without significant variation in readings in half hour sessions. His rolling road used twin HQ discs and plenty of cooling air flow from electric fans. Operated air over oil with the load cell and a tacho hooked to his computer - basic but it gave repeatable results.

[TZ350]

I have asked before but why can't/arn't a big electric motor be used to measure HP accurately?

When I was a Tec at Auck Uni Eng dept in the 80's they had a Ricardo variable compression engine in the thermo lab that I used for checking the octane rating and calorific value of fuels. The engine drove a generator mounted on gimbles. The generator had a balance (torque) arm which you hung weights on untill the pointers lined up. The power from the generator was dissipated in a bank of air cooled resistors.

These are basically a dynometer with a way of measuring fuel consumption, power output and compression ratio. Using a generator as a load along the lines of the physical law of reaction and equal and opposit reaction for the balance arm and P=I2R from Ohms law for power. All the readings and calculations were done manually.

It could be done with a much bigger generator but when you think of a 2kW bar heater being enough to heat a room then 20-30kW of power from the dyno generator is a lot of heat.

Some pictures of old Ricardo variable compression laboratory engines. Ooops I see I have a very nice BSA bantam racer in there too, I think that was sent to me by Sonic_V.

A water and disk brake dyno. The torque arm can easily bear down on a load cell and a shaft encoder used for rpm, then its just a simple calculation in the PC to display HP. An electric generator load could be a similar setup.

Before working at Uni I worked at an Automotive Machine Shop that had a Heenan & Froude water-brake dynamometer. You manually recorded the readings and calculated HP from the Torqe and RPM.

A quick explanation of how to operate a water brake taken from:-

http://www.douglasmotorcycles.net/index.php?topic=604.0

Here we see a Heenan & Froude type DPX1 water-brake dynamometer. Inside the housing is an impeller running in water. The hand wheel controls sluices that increases or decreases the load or friction. The absorbed power is converted into heat and carried away by the water. Partially obscured by the large trumpet at the top is the dial for the spring scale that measures the torque reaction. Not sure when the DPX series first came out, but Heenan & Froude’s first patent for a water-brake was in 1911.

265826

On this side the black rectangular object is one of the torque reaction counterweights, there would be a further stack of additional ones on top of this fixed plate, temporarily removed. At the top is the hand screw for calibrating the scale. The white face dial is a Smiths tachometer for accurately measuring revolutions per minute.

265824

The DPX1 is a rather small dynamometer, capable of absorbing up to 150 horsepower, so was ideal for testing motorcycle engines.


1000 hp Sunbeam the first car to go over 200mph attached to a water brake dyno. Its worth a read.

Great stuff i have always wondered regarding the ellecty motors i think Bosch ones were there is a bit in Robinson about them. Now the software is affordable who knows they could end up everywhere. i just always thought if your going to go to the trouble of making power.... you might as well feed it back to the grid.should be super easy to calulate as well.

Also the Poms were always on the SFC/HP trail as well.
I think if someone was going to make one maybe set up so crank, gearbox, Rear wheel HP could be achievable without all the rule of thumb formulas.
I think the drop is well over estimated as per previous posts.

Oh yeah remember Burts Paddle wheel (Air resistance)one.

so how is the dyno softwere going low ling?

[Yow Ling]

so how is the dyno softwere going low ling?

The software appears to go fine, the dyno drum is proving to be a little more difficult, so I will be making a new centre section
Are you looking for some software? All up the cost was $900 nz that logs 2 rpm channels and 2 analog has a conditioned ignition pickup as well as a drum sensor and usb connection.
The basic version of the software allows 2 runs to be overlayed the Pro version (100 bucks more) allows unlimited runs to be overlaid
The Datalogger is flash as, all smd construction.
Got racing for the next 2 weekends so dont know if Ill get too much done before then

I got the mini USB version

Weeeeeeeeeee we win! We took our Dyno to the workshop and did a few runs the other night. Ended up just using simple dyno for the time being :).
13.2HP out of my very poorly/barely running FXR (Wrong pilot/lean all over, approiate jets ordered) so its probably not that far off. Glen even did some runs on his supercharged bucket.
Still got ventaliation to deal with though! Glen has done a 90% of the work and a great job too, so i can't claim it too much!

[F5 Dave]

Let us know when you have something stable & we can do a calibrating run to compare, was looking at doing Skunks bike very soon so you could bring a bike up maybe.

quallman...did you lot buy a program or make it?

[Sketchy_Racer]

quallman...did you lot buy a program or make it?

Nah we just downloaded a free dyno program called "Simple dyno"

https://sites.google.com/site/simpledyno/

It's limited but when setup is very repeatable, which to be honest is all I car, the actual number is mostly irrelevant to me, but I will try set it up as a back to back with a dynojet or similar some time. It does seem to read correctly though, the HP levels are right the power curve just looks funny because it is reading drum torque and HP rather than motor

Looks pretty good, and it saved you a grand !

[Yow Ling]

Bit of a milestone for my dyno, hooked up both sensors, one for the drum and an ignition pickup on the spark plug wire.
Hooked up the cooling fan, I think its from an old central heating system, got it on trade me

Did a 4th gear run with the CBR150 took 5.8 seconds

Still need to figure out how to export the graphs , but the manual is 244 pages and my attention span is only about 30 pages

274925

might be the most conservative dyno in the country !! 14.28hp

274926

I bought a Datamite Mini USB from Performance Trends in USA, came with all software , hardware and has support which I havnt needed yet, they have online video tutorials etc
the dyno electronics and software cost about NZ$900 but I think it is well worth it.

Now we just got to get our bikes flashed up a bit !!

May be a more realistic reading then some I suspect. It will be good when we have several dyno's on the go, can compare figures and get some good averages. Help to configure the dyno's and know we are all giving out useful and reliable information.

Not taking a poke, but I do remember some dodgy car dyno's back in the day that gave false readings, Bro can remember some that gave readings from standard bikes that was higher then the standard horsepower ratings given by the manufacturer (and these were inflated to improve sales figures), so were quite unreliable.

May be a good idea to get a bulk standard bike and test the waters, that will give a fair idea of reliability. Then you'll feel more confident going forward.

[Yow Ling]

Thanks Seymour, This is the most Std bike in the shed, it just has a pipe and up 1 jet size

Ill run my FXR later today as I have run it on a flash dynojet in Ashburton and also on the famous Harris dyno

Dont want to wind up the neighbours too much this side of Crimbo, the noise control at this stage is just my earmuffs, doesnt help them much though, I had told them about it and they seemed ok.

[Kickaha]

Good to see it up and running Mike, top job building it

[timg]

Awesome Mike :clap::2thumbsup
Waldo's reads the same numbers as Honda Country's dyno if you want something local to benchmark your's against.
All the best for Xmas

[Buddha#81]

be out this arvo wif ya chrissy pressie Mr Ling........we might have to dyno the CBR again........cause we can:Punk:

[Yow Ling]

OK checked the calibration by running my FXR which is 18.18hp on the Dynoworx one , measured 18.12hp on mine
Thats close enough for me

[seymour14]

Yep, sounds like your on to a winner.:clap:

[jasonu]

Yep, sounds like your on to a winner.:clap:

if you can find another 10hp...

[Yow Ling]

if you can find another 10hp...

Another 5 will do, its on its way next week

these is diesel horsepowers , much stronger !!

[F5 Dave]

yeah look where its revving to. Still rather ride your RG chassis TF100. That felt like it only revved to 9500. My arse dyno sez 11.84hp. Loved it though.

This is a similar FXR configuration to yours, std with pipe and it made 14.4hp on the Team ESE Dynojet.

Ill run it in the next few days and see how well calibrated your arse dyno really is

[F5 Dave]

And it will give me time to invoke an excuse about calibration of these big bore engines compared to what I normally race:yes:

[Sketchy_Racer]

For what it is worth we had Kyle's FXR making mid 14hp on our dyno using simple dyno software with around a 7-8 second run. We still need to spend sometime sorting ours out but living in suburbia makes it hard to use it without having the neighbors chase us with shotguns haha

[Buddha#81]

YLR went to the 1st round of the Nats with a Four bike team....... one bucket running in Development Jnr keeping the RG's KR's and Ninja's honest. Well done Jackson on your 3rd.......the rest of us old fat guys made up numbers

...your pit was well balanced I thought...the girth to youth ratio seemed fine to me...well done Jackson...

Round Three of NZSBK this weekend and the full YLR team will be there, Mr Ling himself is taking his bucket as his back up plan, Bren is riding Jackson's FXR and too see if his third at Ruapuna was a fluke, Jackson has been given a YLR KR150 to let him compete on even terms with the other gun fulla's and I'll be back on my FXR cause I can and its cooler than the Ninja250...... Whoop Whoop
