Golly best I put in another ring or I won't be able to keep up.lucky for you, you no yours is relable and ride it fast .. i,m going to back it of i bit for the gp or is may go bang in the first lap )-; . do you have a dyno run of your 50 dave?

[Henk]

Makes my 7.8 look pretty sad

[Skunk]

You guys are talking about 50's with more power than my 125!


If it ain't smokin' - it's broken.

Coming to the GP Skunk? The offer of bad beer is still open.

[Skunk]

No. I'd love to but just can't do it. The bad beer doesn't make it any easier...

Floppy drive on dyno is on fritz. Yeah it's that old complete with DOS. I can say it's somewhat peaky.

I can say it's somewhat peaky.put the pump in and works mint thanks for the link .. the gt has always been a good torquey engine but is 5 speed . last time it was rebuilt was the foxton gp 1998 where it ran like crap . coil or something was going on and of

[seymour14]

So here's some more video from the last round at Kaitoke. The camera decided to look skyward at the end, so cut that section out.

Got some good footage of F5 Dave, enjoy...

Nice to hear the sound of a two-stroke on the dyno...
The mighty GT50. (is this the one that still holds the land speed record)...

I always loved the original bike back in day (having its matching old/bigger version) Scotty has now just made it Very cool....

Turn up the volume; it's mean...

That's a conversation that needs to happen me thinks! But there may be other contenders too!

Does a GT50 hold a land speed record? A NZ one? So many questions so little time :wacko:

125 record is only 119mph, set in 96'.

1995 actually, by R.H. Bleach in Christchurch. :dodge:

I asked MNZ Nicley and they sent me a copy on the Records, all scanned from the old paper, looks bloody neat!

The Latest Records they supplied are:

This is just the latest in each class of what they have sent to me.
I wouldn't read it as official fact, also I may have cocked up typing!

It is interesting seeing some of the names on there!
H. J. Munro is down in the 750 class in 1957 at 143.59 MPH!!!

Edit: They are also all labeled as "Road Speed Record" - I'm not sure if that means anything.



Think is a write up done by Koba perhaps on another forum? (found it a couple of days back) Little food for thought. I believe the same motor is the GT50 we are currently running.

[mr bucketracer]

when i first got the gt was told it ran a 87mph flying qurter but then later told 84mph but maybe some flying some standing or just one way runs who knows

[Grumph]

That 125 record was run in fog on the South Eyre road....ride up the road till he could see the traps then accelerate. Not a nice morning.

i understand that although that is still on the books there has been a higher speed posted but not officailly recognised.

[F5 Dave]

Yeah actually getting it all together on an official day & doing the runs is another matter.

I considered it for my 50, but then realised that bucket rules allow for up to 53cc where as speed rules means 50cc max. Mine is legal bucket, but over size for land speed.

Ha - and actually knowing the bore and stroke of the motor helps too....The same day the 125 record was set, Jane Parret (as she was then) did a heroic ride in fog to break the 250 record by just enough.....But when it came to measuring, the owner of the TZ kept saying 50.7 stroke....I'm in the background going, "no, no, you berk, it's 50.6" the official measuring gear wasn't good enough to pick 50.6 from 50.7 so the record was never ratified....

[quallman1234]

Doesn't Ivan Juggins own the 125 record now on a bone stock Honda RS125?

Somewhere around 200kmh/125mph.

Ivan broke the 125 record, after I made that post.
Took a while but should be on the books, 208kph seems to pop in to my head.

I think 208 one way, but somewhere very close to 199/200kmh with a combined speed.

To be fair, anyone with a Honda RS125 could break it, it was stock and Ivan's body shape is hardly aerodynamic. But good on him, because at the end of the day. To achieve something, you have to do it.

Was that on Hugh's V Twin? I thought they were 56 x 50.7

[Grumph]

Was that on Hugh's V Twin? I thought they were 56 x 50.7

It was Mark Taylor's D. You may be right but the classic yam dimensions are 56 x 50.6.

Given that with the measuring equipment on hand, the barrels had measured up as a tad baggy - and no, i don't know how that happened - and Mark was adamant on 50.7 stroke, the measurers arrived at around 252cc...

The alternative to measuring at the scene had been offered - Kev McCleary would take it away and certify it - but Mark wanted it done then despite advice to the contrary. The bugger of it all was that after it was found oversize there was no appeal available - and because the entry was specified as for the 250 record, it couldn't just go in as a 350 record....

For the record (no pun intended) I'm sure it was not oversize. There's a lesson here for record breakers - always ask to see the measuring equipment that's going to be used.

bikes all packed and ready to go , the 50 had the first blast down the road and sounded as good as on the dyno

[F5 Dave]

8:35 wasn't a good time to realise I'd forgotten to sharkfin the 50. Oh well 30 min work.

[mr bucketracer]

now the gp is all over i'm going to finsh my 550 aprila road racer off , i don't understand computers to well in the way of injecton so puting on some fcr39 carbs on it for the time been

Quicker results I'd think. Good call if they fit.

[Bert]

Right, over the last couple of years there has been many requests from event organizers around the noise levels of bike (four strokers are particularly noisy).

Highlighted again at the GPs this year is the fact that many people either don't care or don't know what to do to bring their bikes down into a lower DB range.

We have been on the quest to shut up our bikes without loosing power and have come up with a number solutions and designs.

So Scotty and myself will post up information for those that care.

[Pumba]

....for those that care.

Fact of the matter is that those that dont care need not bother turning up to events, because it will save the organisers the shit feeling of kicking thier ass out and down the road.

Would be good to have the noise meter at the track at if not every but most event like Bennet did at Te Puke a few years back for random tests and so those that are unsure can ask the question with a clear answer.

I know my bike isint perfect (and I welcome anyone to pul me up on it any time), and my last solution was a insert in the end of the pipe that no doubt robbed some much needed ponies.

[F5 Dave]

I've said to Scotttttt he should make a production run of the underslung mufflers/and/or pipes. Most people just can't fabricate stuff & live in the illusion that less noise = less power.

Typical response is "Such & such's bike is noisier than mine" "Fishe (insert official) has never pulled me up on it"

If there were a few bolt on FXR systems displayed at the pits: Quiet, gain 2hp, this many $$, people would buy them.

[Gigglebutton]

I had a mate who is an audio engineer test our bike with his very expensive meter at different speeds and distances to make sure we were ok, as I thought the bike was to loud. We are under :) He said it is the frequency that makes it sound loud

Probably correct - but it's relatively easy to silence a particular frequency. See The Racing Motorcycle Vol 2....
It's written up very well cos in the UK and probably Europe too, they test at specific piston speeds, hence all your work goes into silencing at that particular frequency....

Not going to be able to get the videos up from the last Round, the new camera is so good, that it takes on average about 6 hours to upload anything! When the quality is pulled back it looks terrible, so not worth uploading at all. Will have more of a think on it, but it needs to take less then 3 hours to upload before I will relent and do it.:weep:

So you are likely more knackered than I am...:innocent: team turbo (go fast or go to bed).


Kel backed off in the last race then had to chase down Chris to wipe the slate for the weekend.
She tweeked and they ended off track in the last corner (all I saw was dust)...
But really impressed with the power it showed all weekend.

Holy crap! Lucky he was off line!

What actually happened was, my glove velcro un did itself, and so i pushed my glove on to my tank to push it back on. A tiny bit later it was time for a gear change. For some reason my head went to race shift and pressed down. I think because last time my velcro un did itself was at Timaru on a 125 with race shift and i did the same thing but it had race shift!
That could of been really nasty!

[seymour14]

Ok, time to fess up (a little bit). We are having a crack at a two stroke conversion (which will remain nameless for now). Having access to a CNC means I only have to find the time, ha ha, that comes around very infrequently!

Still, here is a start point. Trouble is with a barrel, is the obvious, difficult to machine ports! So needs to be made up of several parts, I have knocked it down to 3 pieces, a base plate with upstanding fingers that have curvature in them. The main portion of the barrel itself has the rest of the ports machined into them forming the outside wall of the ports. The afore mentioned piece creates the inside wall.

Obviously once both have been spigoted together and machined down the bore for alignment, I will need to make the last component, that of the sleeve.

Images are a little hard to make out, I have shown the two baseplates apart, partially engaged, and pushed home. I was hopeful for a slight press fit, but they are tightish and the sleeve creates the rest of the structure. Will need to machine exhaust port/stub, and relieve much of the bulk from the outside, also hopefully putting undercut rings into it for snapfitting (and then welding) ample finnage on at the end.

Regan has been busy too, a new tank for a new bike!

Ha.nice to know , I ran a yz80 carb on my 100 at taupo , it was easy the fastest bike out there , after that found small carbs easy to tune on engines that should have larger ones , some silly reson I go back to bigger ones but can't with this so will see how it go's

Yeah only the dyno can tell you what is best with carbs. I ran a back to back test. 30mm PWK V 32mm PWK and the 32 was 1.5hp up at peak and exactly the same everywhere else. Then I brought an FCR. it idles nice:(

Frame looks good! Not much space for a radiator,which I see there next to it. How are you squeezing that in?
Those wheels and forks look Aprilia RS125, very nice. Did the rear wheel fit the NX4 swing arm easy enough?

Did the rear wheel fit the NX4 swing arm easy enough?a nsr 250 radiator fits fine with enough wheel to radiator clearance can put another one under the front cylinder if i have to , have not fited the rear wheel yet but will have to run a 125 tire on it as the 150 tire is to wide , if you have ever seen a 120-125 tire fited to a 4inch rim they look not to bad

[mr bucketracer]

if i was to do another i would use a nsr gull arm swingarm i think it would be the go, just a little wider to take the wider tire

Love days like this.

Was sent a dozen high school students today, and was told to make whatever I liked, Design it, Cam it up, and make it.

Racked my brain and oddly enough it started thinking Buckets...

I remember a certain North Island Series that ended oddly this year, an extra Round that didn't materialize meant we never got together for a prize giving, or for that matter, any trophies. Oops!

I took it on myself to knock something up today, from scratch. Richban, you must teach me how to take photos of glasslike objects, I sucked. Guess it would take a pre digital age camera to do it properly.

Anyway, will dole this out next time we meet Rick!. A-Grade 1st,2nd,3rd.

Progress is being made. Machined most of the shape into the barrel, still looking too bulky at present. Will shape up the top third of the barrel for better cooling later on, plus finning. Exhaust port is next, lots of yummy long series endmills and ballnoses to come, should be rattly as usual, better find my earmuffs...

What CAM software are you using for your code?

[seymour14]

What CAM software are you using for your code?

SolidWorks/SolidCam.

Have had experience with Rhino, Powermill and MasterCam, but this is the one freely available to me, and I must admit that it is quite user friendly (considering I am self taught). Each had their own quirks, but like anything, it comes down to being precise with your setups and thinking threw your designs and mill strategies.

Finding enough time to finish when you are getting on a roll is another conversation entirely!

Cool, I used solidcam for a little bit but work used Esprit and I had HSMXpress at home for 2D stuff. HSMXpress integrated into SW much better than the others I found but was a little more limited in toolpath generation.

Longest program I nutted out was a injection mould insert that needed 3D milling on the 4th axis. Took a couple days to get it to all work!!

Once the cylinder is completed are you going to weld the insert in to cover over the transfer ports then get it plated or are you going to sleeve it with cast iron?

Looking at a Nicasil lined sleeve, press fitted in with a top hat arrangement, and may put a little extra "bump" on the top hat to act as a location means. The plating will come at the end and I will see if they can line the ports with it as well, no real benefit, but it makes it all similar throughout with a "skin". Depends whether the process allows for it or not.

[F5 Dave]

I'm just closing my eyes wishing I could do something like that. Makes my 1978 MB look like an axe.

Don't worry Dave, I'm not going to talk this up. Interesting project and I will give it my best, but it is very much a prototype, the day it comes to fruition we will all be standing around the Dyno with bated breath.

May become a very pretty door stop....

[F5 Dave]

my concern would be the differing expansion rates but with the sleeve it should be sweet. I can't see it being anything other than a little bit awesome or better.

Judging by the relatively few nicasil cylinders I've dealt with, it doesn't "throw" very far. About 1.5mm into ports in my experience.
This leaves an edge which should be stoned for the good of your rings...
I'd imagine that to nicasil coat transfer ports, shaped anodes would be needed - and expensive.

That is good to know, very little practical literature on the net on the subject. Can't go to extra expenditure for a Bucket!:msn-wink:

[Sketchy_Racer]

Thinking about the thermal paths, I recon that it would be vital to have as much of the cylinder as 1 piece. Thermal overload will be the HP killer here if you can't get the heat out it will be game over.

Keeping in mind that it is fairly well proven now by the ESE guys that it's a tough job to reliably shed anymore that about 28whp worth of heat.

What's the plan with fins? Going to machine them into the cylinder as it sits?

Regan has been making scoops for the bike which should help. The top third of the cylinder will be scalloped out, like a flower pattern as it comes out and around the studs. I am going to do some trick stuff there as well, but it will be a case of a picture says a thousand words, so will post pictures once done. Finnage will be as much as is practical, and I am trying a new concept here as well, again pictures will be necessary. Needless to say, the fins will be welded on after, and will need to suit the confines of the GPR frame.

Shall try to do a little bit more each week, but this is the "go" season at the moment, time is at a premium.

[seymour14]

Great show, we did our bit. Played clips of the racing and got a good response.

Images from the show.

[seymour14]

Fins coming together. Deep grooves machined in barrel to aid cooling (the curved face you can see on top is machined in two more times at 10mm intervals below), fins will snap fit into the shallow portion, get welded, anticipating at least 6 differently machined fins to be put on. Exhaust port means a little bit of shaping required for some of the fins.

Hopefully pictures are a bit more self explanatory.:cool:

[Farmaken]

Dang, she sure is purdy ....:love:

[seymour14]

Dang, she sure is purdy ....:love:

Just for that, I have given it a makeover...:msn-wink:

Latest developments are 6 fins, these will snap fit into grooves machined around the barrel for good engagement. Then welded down the fins seam, or welded to the exhaust port, depending on their placement. The two "whole" fins will have a bandsawed slit put in them to get them into place.

My rather unique design has a third more surface area on the top. Hot air rises! It may even help break up the airflow directed onto the head via the several air scoops. Either way I do not expect they will provide more then a couple of percent extra cooling aid, but it will be interesting to take measurements from these fins once in action. The largest fins are 200mm square, very similar to a 250cc or 400cc CZ motocrosser for comparison.

She will be distinct, that much is a given.

Some more machining required in the exhaust port, then it will be the all important sleeve. That will be a challenge indeed. Post pictures of the one I get right....:rolleyes:

In the picture you will also notice the mandril I quickly knocked together for holding the barrel in a dividing head as I machine the rest of the grooves that go from the exhaust port round to the opposite side. This is for the four lower fins, I want good engagement.

[Grumph]

Good engagement....there are several high temp epoxy fillers which are metal based so have good thermal conductivity properties. A fillet in epoxy may help....
Some years back a customer who made light fittings for a living was having problems holding thermocouples onto fittings for heat tests. I asked a mate at Air NZ workshops and got some very high temp Araldite which they use for gluing thermocouples onto jet combustion chambers. Can't remember the Araldite number sorry, but these things are about.

Good to know, however I am just relying on the Toolmakers curse. Exact tolerance. The weld should pull them in nice and tight, and they will pull into the gap snugly as well. Should be plenty of swearing if they don't.

You will probably hear me in Christchurch if things go pear shape.

Thanks ... and its true, at the moment you don't need 30+ hp to do the business, but I expect it could help.

This is where I got to before wrecking my 31hp cylinder, at the time I did not understand the importance of retarding the ignition when running part throttle. After that I got a TPS and ran a 3D ignition map.

299976

This dyno graph was about balancing the main and air correction jets. Blue line = bigger main, fitting a bigger air correction jet leaned the blue line off at the top end to keep the air/fuel mixture correct as thr rpm went up. And after a bit of work it eventually matched the Red line (smaller main jet) for max revs while still having a smooth start to the torque curve.

Seymours cylinder is a very cleaver piece of work, I like it.

i think for are team its been fit and young is the problem the bikes are up to it . but we are fadeing of . so hp and lap times would be a better gain at the start of a gp and hope for the best.. years ago the young guys had slower bikes and the old worked out how to make them fast so was a good leaver . but now we are giving the young guys are bikes because we or i was a has been lol :shit: and like to watch them do the business

Not quite finished, have quietly set up the barrel on a dividing head and machined the remaining undercuts in for the fins. Next will be the final cut inside the exhaust, difficult set up because yes, it is bridged, and I do not want to nick it at any time! Still ticking away at it, the closer it gets to finished, the more I want to keep at it.

Yes I know what it's like, I thought I might take a week off and get stuck in and finish a few projects BUT, one employee suddenly takes nine weeks off to have a trip to Europe, busy nine weeks for us. Now next employee wants a week off for a trip to Australia. We are at a busy time too so no weeks off for me! Never mind, relaxed employees, lucky the boss just does what he's told.

We got close with it. But it never really made it to its full potential.
We had a plan about putting into a FXR frame and sorting it out before it went back on track, but this year has been a little busy with other stuff. Maybe we should try and shoehorn it into the Tz125 frame???

[seymour14]

You may have figured it out by now, but if not, by invitation Team GPR have done a trial "noise test" run at Sherriffs Road Kart Track, Palmerston North. Anyone who knows our bikes will understand that when I say that we were on the noise limit at the track today, that there will have to be some extra muffling work done to our bikes to quieten them down a little. This would mean that there would have to be a better muffling solution needed for everyone. Maybe two strokes being the exception.

The crackle of a backfire put the bikes over the limit, but even normal racing was on limit. The Karts by comparison were seemingly 10 decibels quieter at any similar points on the track. This is going to have to be sorted if there is any chance to proceed further.

On the other hand, we got a really enthusiastic and warm response from the Kart people today, and that was a real positive boost. Morley Sherriffs heard us racing from up the road and next thing you know he has come down to look, excitedly rode home to get his not quite "track legal" bucket, but everyone had a hoot watching him go for a ride on his beloved home track, gumboots and all!

I rode Brents bike, John Sendall got a couple of rides in too, Scott, Kieran and Morley all got out there. We have more to do, but it is a great start. Small video to follow.

[mr bucketracer]

at the road it needs to be 65db max , the odd pop and bang made us 2 to 3 over , even though he said some super karts are 10 over it would be nice to work well in the limits . so going to work with exhursts and see what i come up with , even if it kills some power . the 2 strokes are not so bad

Nice work ! Looks like a great track, round 4 of the NI series ?

[jasonu]

Yep, the same ones he bet you on in the GP of years gone by...!!:lol:

Same tires and petrol too I'll bet.

[seymour14]

Three more update shots. Showing firstly the six undercuts for the fins, they may get welded in later this week.

Another photo shows all I could achieve looking down the exhaust port, any more set ups would have to be compound angles (tipped in two different directions at once), and I think between that and the impossible datums required, this may be pushing my skills too far.

So the third photo shows the ports on the inside (minus sleeve at this point), left has blue vivid on it to show where I am heading with this after hand porting it, the right one shows just how much more material needs to be removed. Patience is a virtue!!!

A false sleeve will be dropped in to help guide the transition, left as a sliding fit, but able to be engaged on the notch in the "top hat" for positioning. The final port positions will be machined into this false sleeve, and it should help immeasurably in getting us 99% home.

So it continues...

We all need to wish very hard!

I think in time it will become viable, but the noise factor is going to have to be overcome, and I think we will need to find an easy muffler solution, even at the cost of a horse or two. If everyone suffers the same, the racing will still be great, and it is a great track to ride, very technical, but good width to work with.

Keeping my fingers crossed.

[Bert]

Nice work Kerry.

Right so the new MNZ rules are out. Be sure to read them and check off the changes.

http://www.mnz.co.nz/docs/default-source/Newsletters/mnz-rule-changes---to-be-linked.pdf?sfvrsn=2

Outside of the code of conduct changes, only thing that seems to have points structure and the deletion of rule 24.2.1

24.2.1 was
Fuel: See 10.17.1. Alcohol based fuel or fuel additives are prohibited.

Linked to 10.17.1
The following classes shall be restricted to petrol having maximum characteristics not exceeding “Avgas or Unleaded FIM” as defined in Appendix E. Motocross, Stadium/Supercross, Miniature TT, Trials, Enduro, Cross Country, ATV, Stockbike, Solo, All Road Race classes except those classes listed in 10.17.2 and 10.17.3. All Mini and Junior classes.

Linked to appendix Ehttp://www.mnz.co.nz/docs/default-source/rules/appendix-e---fuel-specifications.pdf?sfvrsn=2


Now with the rules 24.2.1 being removed, what controls fuel inside chapter24...
E85???

More holes than the bible...

[Henk]

yes they liked us out there and want us back so will work on a starderd muffers that will suit 4 stroke 150 bikes

If you can do a header pipe combination for FXRs at a reasonable price that works OK we could almost make them mandatory.

Certainly will give this our best shot, knowing how many times noise is brought up at all the tracks we go to, it is worth finding a "fix all" for this problem. Will keep you posted, it is happening as we speak.

I was against the change. Simple is better and the seem to have done is complicate it for average joe.

Based on my reading of the Fuel Specs, we are required to comply with 10.17.2. And Appendix E states that for unleaded petrol it must not contain more than 10% Ethanol, therefore (as I understand it) E85 is still prohibited.

24.2.1 was certainly clearer

[Henk]

it must not contain more than 10% Ethanol

24.2.1 was certainly clearer

We draw the line at iStout then

Like yourself, I'm stuck with dealing with this sort of rubbish everyday.

But Chapter24 was almost inclusive and covered everything one needed to really know (outside of C-o-C and racing stuff). But now man it's been degraded into the same level of bull as the rest of MOMS. Maybe a few of us need to re write chapter24 and hand it back to MNZ for next year...

But way I read it 10.17.2 doesn't apply as we are separated under the racing classes and not defined in the clause.... But I'll read it again...

[Pumba]

Fighting with roading scum to update our contract doc templates to the new 3910 standards at the moment. Should have been done months ago. Over it.


All Road Race classes except those classes listed in 10.17.2 and 10.17.3.

That it is that single sentence why I believe we are covered.

Are we keeping up with cross posting in the two threads...

Yes, valid but we are classified as miniature road racing.... The 'miniature' is enough to warrant reference....

We made some good headway pre GP this year, knocking both Scotty's and mine back quite a lot, compared to the rest of the pack.
But I was shocked at how loud mine was at manfield two weeks ago vs big bikes and then at the kart track I was really blown away compared to the test Karts...
Bloody four strokes...

Might have to have a lie down shortly.

I see your point. Back to my original statement. I was in favour of 24.2.1.

I can't give you any positive feedback... Maybe I should red rep you instead for making so much sense...

[seymour14]

Another day in paradise. Got a good burn going at Scotty's tonight, just the usual, flames 4 stories high, bloody gorse...

Helicopter came over, piss off fire brigade, just a Griffiths burn off, sweet as. Came down the hill and they were putting out another fire a 10th the size of the burn we got, must have got confused and got lost getting to his place.

Then Simon and Chris turned up, having been on a RS pilgrimage south of us, we could have cleaned up a bit, but great to see them both. Looked like they have secured the sweet deal, and were doing the Auckland-Wellington round trip in a day. Motorcyclists, what can you say, we are a bloody minded bunch.

They will no doubt fill you in with all the finer details, but it looked a fine machine for their growing stable.

Quiet drink needed now, maybe more fires tomorrow...:devil2:

Oh please.
Just be happy the common sense brigade stopped the 100cc oversize submission.

Back to the real issue at hand NOISE.

I stumbled across these Yoshi NSF100 pipes. What happens if we try this and add in another at the end??

300591

And a shame these swingarms aren't long enough

[mr bucketracer]

in what way is that swing arm to small? was going to try the same thing with the pipe on my bike , if it works i think it will be the way to go

Made for NSF100 with 12" wheels and direct mount shock.
