RG100!! came over to stay for a few days and we got bored at midnight of watching crash kings and we decided a coffee and a stereo and out to the shed we go to work on XL motor, we set to work with a high caffene coffee and ended up getting stuck with electrics so in side we came went on net and checked out wiring diagrams while having another coffee then got back to work, we ended at 5:00 am with no luck:sweatdrop .

Wake up at 11 am this morning and get back to work to find the motor has had CDI top end added and Points bottom end and someone had butchered it, deciding what to do we mucked around on it then we decided to ask Dadple if he had a motor for parts (thanks), we ended up scoring a CT125 motor of him which is a full CDI motor but was siezed from sitting so we pulled it apart and cleaned the piston up finding it had a high compression race piston in it but the barrel was a bit scratched so we put the XL barrel and head on it and the standered piston was more modern than the high compression one, so we chucked that in and kept the other for spares kit, we chucked a plug in to check compression and it was alot higher than stock which should be good but now need a new CDI as my CDI box is fucked:slap:

Steering lock? Good grief, why the hell have you still got that attached? Just pull the plug & take it off & rig a kill switch to the light switch & earth.

Next you’ll say you have the helmet lock, & rectifier regulator still on.

Please don’t tell me you leave the poor thing outside.:wacko:

Ivan WTF get your ass into gear, isn't it the holidays ? get into it man. though in saying that. I've stalled on mine, but getting there slowly.

RG - looking good. i think the slicks might make a difference. did you find my post about the rear sprockets, this might make all the difference at manfield. and whats the story about selling the cbr, you'll be fast enough on that,

good luck boys get into it...

Sketchy_Racer

16th January 2006, 18:50

hey bert,

the reason i am selling my CBR is that it is worth more as a street bike than a race bike. Then im gonna get me a fugly RG or KR 150 !! that way i can afford new leathers etc, as the ones i have at the moment arent mine.

sounds like a plan stan??

good Onya !

and the reason i say sell the CBR as a street bike is because it is still regestered so i dont have to get it revinned :yeah: and i also got lots of parts coming :Punk: so it will be cooooollll

Ivan

18th January 2006, 20:00

got me all the elctrics

Ivan

19th January 2006, 07:58

ok the electrics are off a quad and I had the pulser pickups the lot on those cool female plugs and they just clipped up to a male plug and then I think the other wires are lights etc they are brown and shit I got wires from pulser pickup to CDI and then wires onto the coil but last night that rear axle stand you saw RG100!! the pole to it bent so I cant sit on it or else it will slide of bench. This got my hopes up a little more thing that I am that close now and just need to get it sparking then the rest is a piece of piss. I am going to race this bike only a few times a year this year cause I might as well since Im at Weltec do the motor right up

Is that motor I gave you crap?

I have got spark on my motor now and am going to start it tommorow, It is also bolted in and may have a petrol tank from a scooter since they are about 4 litres and small so it should be a minta bike will have to post some photos

Ivan

21st January 2006, 01:04

Ok I have quad electrics on the motor at the momment but have a Exhaust system CDI and Carb coming in from Thailand, I am doing the motorcycle mechanics course at Weltec this year and am going to tune the fuck out of the motor, i will bore it to 150cc and maybe run a oil cooler cause I read for aircooled motors that are used for high performance it is good to run an oil cooler system

Sketchy_Racer

21st January 2006, 08:22

you wont be able to run a oil cooler..... not without some serious modifications.

but boring it out to 150 sounds like a better idea.

oh and when are you coming over??? and when you do bring me some new tires! for ma bucket

drill out the RG forks and AX swingarm. Thinging of drilling as the best option as I have axles for the wheels. Then it's just the spacers to sort.
The clip-ons I had make don't fit. They aren't quite the same as the design I gave but can be machined. Can you post a pic of the ones on your RG Brent? I might copy them.
Also been offered a KH100 with a buggered motor at a really good price. Told it is setup well (clip-ons, disks rearsets etc). Haven't seen it yet though.
What to do... :crazy:

Yeah I know I am only getting the parts from thailand cause they are cheap.

I had the same problem when I joined there were alot of guys on bikes that were buckets but over the last few years I have seen buckets go a little far,

Im just hoping that with a nice chassis like this one and a old 70-80s tech motor with minor mods will perform well.

actually do any of you guys have a bored out xl,ct,tl 125 to 150 barrel:Punk:

30th January 2006, 16:10

This " when I started bucket racing blah blah blah now it's just the $$$s" thing has been getting brought up over and over again for as long as I can remember. Theoretically buckets should now cost more than a Yamaha M1. Funnily enough they don't. Also with "ALL" the changes that have been made to the regulations it is still the same "old school" buckets that are the fastest. To go fast does cost money, that's the way it is, even in bucket racing but fast buckets don't cost any more than they did when I started more than 20 years ago.

hummm bugger I was sure that they were the same size, I'll have a look and see if I've got some bearings that will do the job, sorry mate.

bugger about the clip ons. I'll take some photos tonight. If you struggle I'll lend you mine until you get yours sorted.

Ok what Have I been up to ??- Sweet FA (to much cricket not enought time in the shed). though thanks to bucket'n'bits my tank has arrived today, so now I can also sort out my seat.
started to bend up my front engine mounts, and I've finished the mods to my chamber, which should give it abit more low-mid range...... ???
Striped down the engine and given it a new ring + main bearings etc.

so with some hope it might be finished by sunday - monday.

TUI

may take photos when finished but not before, should really be a suprise for manfield.

hey bert,

with your clipons, Do you leave them a litte loose so that if you crash, they fold in rather than bend??

I think im gonna make some for my FXR cause at the mo, they are very bent from my last 'off'

oooo'yes - but I use to fall off alot:angry2:

I do them up as tight that I can't move them, but when I hit them with a rubber hammer they fold up (around 24-26 foot pounds).

as for your clipons - heat them up and straighten them (steel use a oxy kit, ali throw them in then oven at 280 degrees and slow bend them back to shape, - don't forget to ask mum and do it over several attempts, let them cool slowly in the oven). though someone might have a better way.

- no need to buy new one's. (and don't fall off on that side again).

Bert

Can you cut slices into the inside edge then bend and weld it? Or is it too tight for that?

Picked up a KH100 last night. Bugger me - it's got a RG50 front end, complete with clip-ons (guess where that's going...). Motor in it is beyond repair. So is the gearbox :nya: so I'm looking for a Kwaka two stoke motor and box. Rear swingarm is off a Suzuki (E Full Floater) with a 17" wheel. Some of the older Wgtn bucket guys will know the bike. I plan to get it and the AX100 running.

What's the deal with running two bikes in the same class? Can I swap each race or do I have to stay on one bike for the points (like I'll be in the running :blah: )?

1. front mount (going simple square after mondays cockup)
2. finish welding up zorst
3. transplanting race motor ( no doubt something will need to be adjusted)
4. bleed brakes
5. mould rearsets and pegs (might use old one's to save time)

yep those rotory (sp) valve induction motors are pigs to work on and get power out of, but once you have, they are dam fast.
What you need is two bikes with the same motor so you can play with one see what works.

Bert

3rd February 2006, 17:25

Skunk, you could of course run a KH or maybe KE125 if you had a 24mm carb

Skunk - i think i've got a 24mm in the shed if you find a going 125, but you would have to mod the intake slot and do some work on the rotory valve to make it worth while, and thats before you even start on the porting.
Stick to what you've got, old AX has alot of untaped power ready and waiting for someone to find out how to get it out.

4th February 2006, 07:52

The AX100 is a runner so I won't be stuffing around much with that much. I have a ported barrel from Ivan to go on it when I've sorted the timing out and made a pipe. I don't even know what rev range I use yet so it's a way off.
The KH100 is a project. Find the best bits I can and build it slowly.

Cheers for the carb offer.

What's the easiest way of hooking up a rev counter? I know nothing of two stroke bike electrics (only car).

Look and see if the AX has a mechanical drive (for the rev counter) and go down to B'n'B and get the cable and counter, if not then it's quite a effort to sort out.

+But here go's another cheep way:
1. find the connection between cdi and top coil and slice and measure the voltage (while the bikes going~100v) this should pulse every time it sparks.

2. find someone with a pic micro programe kit, and a pic16f84a (5-$11) and setup a programe that records every ten pulses then calc the average time - convert to RPM (a pulse output). - note a series of resisters will need to be connected in parallel to drop down the voltage to max 2.5v.

3. the output can be connected to a pushbike speedo. then set that up as a 100.1 setting. then you will have 10,000 rpm displayed as 100km/h (this is a cheep way). - talk to skelstar he seems to knows abit about electronics and might be able to build something for you.
(the above is how I am tring to building it - but I've been working on it now for 5 months:( )

or

buy a inductive pickup RMP meter for a gokart that straps on to the sparkplug lead. $$$$

other than that you're stuffed - these old two strokes are a pain to get a RMP gauge for.

actually do any of you guys have a bored out xl,ct,tl 125 to 150 barrel

I have acquired a XL125 bucket that I am considering stripping to sell as parts. Just want to get it running first. It has no spark. Do you need to run a battery to make these things spark?
PS. You do if it's running total loss ignition with no rotor, as I noticed today.

It also came with a spare barrel and piston.
The barrel is marked 124cc. is scratched in one place and is ready for a rebore. the piston is a 150cc piston for it so I have been told.
If it's of any use, let me know, and I will pop it on trademe at $1 reserve.

yap am keen Racey but dont have a trade me account:slap:

if you have no fly wheel you need a Battery but that can become a hassle at times if you can just throw on a flywheel (points or CDI Ignition?) and then try get a standered wiring loom and go from there but if it is allready wired just get a battery and go for it

I do want the barrel and piston!!

but not the same weight, and lose a caliper and disc off the front, then change the master cylinder to get the braking power back. You are NEVER going to fade even one of those discs. I've got a NZ250 front disc on my bucket and even at Wanganui it doesn't fade. weight is a big killer of performance on a bucket and to make it even worse, on your bucket it's unsprung

Do what I did, get a GT50 front hub and lace a 17" rim to it. With some fossicking round you can still find decent priced rims in the wreckers, then you need spokes and a friendly person with a spoke threading tool. The rear was built along the same lines, find a hub, I used a drum brake item, get a rim and lace it up. The end result was nice light wheels with OK size rims. Failing that try for a set of RS wheels, but as you mentioned price they may be a problem. You will have to piss around with mounting discs and getting caliper mounts made/modified. It can be a real pain unless you have access to a welder and machine gear.

I already have one 17" rim but I'll have to count the spokes. I have an arc welder and bench grinder so that can take care of the brake offset in any case.

Dumb question: GT50? Suzuki, eh? How many spokes, or can I count them tomorrow?

Ignorant Ginger Monkey first time I heard that :lol:

Yeah Im with Kick tho you can throw anything a chassis with work

Sketchy_Racer

5th March 2006, 08:18

I dunno. I Think for the effort of getting a RX100 or something to fit in the RS chassis is beyond the point of "within reason"

and the only reason glen gastons on is any good is because he has spent time getting a chamber and porting etc. No bucket engines (well older ones) are 'fast' when you get them. If you put one of them in a Rs chassis, you will still get your arse kicked and still moan about "not enough power" and you know it.

Why dont you sell all the bucket stuff that you have accumulated and buy a FXR 150. That way its already a good bike and you dont have to stuff around with it, Bar putting some new tyres on it. Thats all myne has !!!

Getting the point yet you "ignorant Ginger Monkey!!!!!"

Nah a RS Chassis has alot of room for a 125 air cooled 2 stroke motor, I am thinking RG100!! is still jealous of my chassis and he wants it that is why he says sell of all your gear and buy a FXR, all I gotta say is Fuck that:angry2: I dont want to get rid of the RG50 it was my first bike and we get along like a good married couple one day itll be in a good mood and ride real well and the other days it can get a little cranky and decide it wants to crash and then bog and splutter after wards,

speedpro

5th March 2006, 20:38

It isn't easy to fit any 100/125cc engine into an RS chassis because the motors stick out too far to the right once you have the sprockets lined up. If you sort out all that, say by watercooling the motor to make it narrower, then in the case of my MB/RS bastard the bloody carb mounting rubber bit is perfectly lined up on the shock mounting cross brace and only about 10mm away from it. The carb will also be about 50mm "into" the bottom of the tank. I've figured out ways of sorting it all but it's going to take some serious time in the garage with a TIG welder and a big pile of Aluminium scrap.

Time and a TIG welder are both problems at the moment.

A thought - a rotary valve engine would get around the problem of the carb versus shock mount, but the carb will be sticking out in the breeze far enough to cause ground clearance problems I would think.

It isn't easy to fit any 100/125cc engine into an RS chassis because the motors stick out too far to the right once you have the sprockets lined up. .

I think the guys here mounted the motors then sorted out the chain line at the rear wheel, I know the #9 bike had to have some fins trimmed off the barrel but I dont think #17 did, both had to modify the top shock mount and #17 also had to to the bottom of his fuel tank for the carb

#9 (Rod) spent around $400 on tig welding alone but #17 (Darryl) had all the gear to do his himself

If you look at the side on pic of each bike you can see how on Rod's bike they modified and used the lower front RS engine mount but Darryl did away with it and used the top head mount

I also thought of putting in a jackshaft between the engine and the rear wheel. That way the motor could be mounted centrally and low out of the way and feed power to the jack shaft which would have a sprocket which lines up with the rear sprocket. It all got a bit tight for space though once I sat down and mocked it up.

The CT 125 has had a XR200 head and cam added which the head has had the ports reshaped and smoothed valves got lapped in timed and today at Tech we took it outside gave it half a dozen kicks a big bang possibly a back fire? and then it fired into life idling away but the base gasket must have a rip because the oil started leaking which sucks so now I am as happy as a sandboy it runs better with the 200 head and cam than the standered 125 one no carb adjustment at all it was mint:msn-wink:

Im really stoked that all my hours of hard work and swearing cam through now im gonna bring it home and modify the exhaust pipe

Also I have started working on my TF100 suzuki which is going to fit in a RS125 honda chassis. I'm really stoked I just now need some port specs for a TF100 barrel cant get hold of Bert he seems to have disappered right of the face of Kiwi Biker

I had a TS100 that went pretty good. Made 19.9hp 15 years ago and it was big and fat. The basic specs said it should have been a peaky monster but it wasn't. It had 200deg ex port duration, 200deg intake port duration, and I think around 132-135deg transfer port timing. It ran 14.7:1 compression. I completely devconned over the intake reed valve to make the intake a nice smooth thing from the 32mm carb right down to the piston. With the extra intake timing there was no need for the intake reed valves and I figured they just upset flow in the port. So it was a pure piston port motor. I spent ages getting the exhaust and intake port shapes "just right". Pete Sales did the transfer ports. Even only revving to about 11,000rpm it still ate pistons even though I was using RG400 rear cylinder pistons. Another issue with these motors, even if you use the TS125ER bottom end, is that the gearbox is useless with a gap between 3rd and 4th. The clutch is marginal as well. Compared to say a Honda MB100 the crank is agricultural but with good phenolic cage bearings with C3 clearance they seem to last OK. For some reason, even though the combustion chamber had near identical dimensions to ones I used later, and I used the same ignition system, it also had an appetite for plugs. I used to change the plug and piston every second meeting.

What I'm getting at is - Don't expect too much from these motors, and even then it will take a lot of very careful work. Get a torque wrench for the head studs as well or you will pull them out. Prepare to throw parts at it if you get serious.

I wouldn't bother going to ALL the trouble to fit one of them into an RS chassis.

Ivan

31st March 2006, 10:12

Yeah sweet as but from the ones I have seen both of RG100's TF's they seem to go like snot and also last for ages. Bert he hasone andis only having a big end bearing issue but his one will be fast as well did you ever think that with upping the compression so much is going to cause the piston to travel higher andwhen it finally combusts it is going to have so much force being pushed on the piston that you will blow holes straight through the top and about the spark plug go to a hotter plug.

Any way I got my parts today from Bert and am going to get my barrel ported tommorow and get the puppy runningI have also been told that the engine mounts toan existing RS mount which I was happy with

as well did you ever think that with upping the compression so much is going to cause the piston to travel higher andwhen it finally combusts it is going to have so much force being pushed on the piston that you will blow holes straight through the top and about the spark plug go to a hotter plug.

Compression doesn't alter the stroke and therefore how much the piston travels. As for the force bit - that is more or less what the aim of the whole exercise is, to create as much push on the top of the piston as possible. Unless the piston is faulty it is never going to push a hole in the top. Once you start making horsepower and running hard the motor will need a colder plug. I ran a "9" series plug. On the kart tracks I ran an "8" a few times. It made no difference to how long it lasted and looked a bit hot for comfort. I also ran an "8" on a faster track once (accidentally) and I got a little fuzzy edged crater in the middle of the piston.

Getting back to compression, my current aircooled motor runs 15.3:1. The new watercooled motor runs less as supposedly (and hopefully) with all the trick porting and pipe there will be more gas jammed into the combustion chamber and the compression ratio had to be reduced to compensate.

Pic 1 before
Pic 2 After

I had it running yesterday as well but had a problem with it the timing was out 1 tooth to much carb blow back but it runs and I found out the CT barrel has a hair line split in it and when the oil pressure builds up it forces its way out must have dropped a cam chain at some stage and blown a hole in it O well I am going to throw the XL125 Barrel in which runs a high comp piston as well as running the ported 200 head with shiny valves:clap:

I am running it in at the momment as well on 2 stroke premix lol lubes the valves and bore seems to be working its ELF 2 stroke which is sticky as shit as well so by today I will have a high compression 4 stroke bucket I wanna see if I can get access to a dyno somewere once it is tuned properly to see my horse power and tune it for low to midrange power.
Anyone else got any mds to perform to the 4 strokes might get my cam reground

I have to put the muffler on now because all the oil andgrease spat out over the back wheel and woulfd cause you to crash I just need to wait and let all the smoke clear which could be ages cause theres so much grease I should take a pic while it is running to show you guys what I mean:lol:

Ivan

7th April 2006, 10:20

Ivan I can see that you are enthusiastic but PLEASE get friendly with someone who knows what they are doing.

Just two examples of "iffy" things you've said or done - putting the exhaust on to stop the valves dropping and putting oil on the bore, even if it was 2-stroke oil, when you assembled the motor. At the most you could put maybe one little drop of oil on the skirt when assembling.

I'm hoping you used new piston circlips when you assembled the motor. I make it a point to destroy old clips when I take them out just in case I get tempted to reuse them. Buy a packet of them, they are cheap, and then there is no excuse. Go get a couple of bottles of different grade Loctite as well, and one of the best buys you could make is a "good" dual signal torque wrench or a "break-back" type. You will never regret it.

I may not be the flashest at this stuff but I do know if you dont have an exhaust header it causes the valves to drop after awile I was told this by a fewgood mechanics

And I know that alot of guys dont care but when you dont have any money to spend on ya bucket engine you are gonna do everything and the most damage is caused in the initial start up whilst everything is dry think about a dry piston anda dry bore for that first few seconds whilst its dry is gonna start damaging stuff

Re the exhausts and valves - If you are stupid enough to run without an exhaust then you would probably be stupid enough to do (or not do) something that would cause a valve to drop. Running without an exhaust system will not by itself cause a valve to drop. Drag race cars only have short pipes to get the gases to somewhere where they won't set fire to things. Aero engines in light planes typically have exhaust manifolds that get the gas outside the cowling and that's all. A typical fast bucket Honda single motor will occassionally drop valves even with an exhaust system due to the cam required and the revs they have to run at. Things break because of the hammering they get at revs, not because there isn't a bit of pipe bolted on somewhere.

There are lots of theories about assembling motors and how much lubricant to use on assembly. If it's a new piston in a fresh bore on a 4-stroke all the fast guys I know use a drop (or two) of oil on the skirt only of the piston. This includes everything from 125cc Hondas to 8.2L blown methanol motors. By fast I mean current or past NZ champions. I've assembled 4-stroke engines with stock cast pistons through to forged JE pistons and have always done the one drop of oil thing. I have never had anything that even looked like a problem caused by lack of lubrication. Note that this is what I've done, NOT what someone else has told me they think is a good idea.

I think Ivan is OK, afterall he does have an RS125 which is pretty good, and he seems pretty keen if a little misguided. It's all good youthful enthusiastic stuff. It's taken me 20 years of racing/fiddling to fully comprehend that others know more about getting stuff going fast than me. He'll get there. In the meantime it would be nice if everyone was a bit less critical of his efforts and a little more supportive. We'll just need to be a bit more tolerant of his "youthfulness", me included.

An example from my youth which is fairly relevant was an old XL100 which I ported. It was way slower than a standard one, which was lucky considering the brakes and handling. The muffler was suspended by a bit of lockwire to the frame.It's a kinda similar picture to what we have here except that this bike is making lots of power. (oops!)

Hey guys I have to do the ports on my TF100 but that isnt going to be hard have the Dremel kit to get in there and do it just wondering while I have the motor in 2 halvesof there are any other mods that I can do to it in the bottom end I will also make a chamber to suit am looking at an internal roter flywheel real small but like to produce the power real fast the same asthe one on my RS

I have read that if you have a large flywheel on a peaky motor helps smooth down the sudden rush and also produces off the line torque more
and a smaller flywheel allows the power just to kick in straight away

Hey Ivan, before you grind anything, have you got a plan. "Failing to plan is planning to fail" goes the old saying. What are you going to do? Raise the exhaust port ? widen it? how wide? how high? Are you going to do anything to the transfers? Have you got an old barrel to practise on? After all why bugger a good barrel practising. What sort of cutters have you got for the dremel. Will the dremel be able to get where you want to be?

You could match the transfers to the crankcase , check that the base gasket dosent poke into the transfers. Or you could just put it back together standard and live in the knowledge that it wont blow up for a year or two provided you give it a nutritous diet high in vitamin TTS

Stanko is exactly right. You MUST have a plan about exactly what you want the motor to do and everything you do is to achieve that. Have it all planned before you start. If you go making the ports real big on these motors you will need to feed pistons to it as they will crack all the time. Are you going to raise the whole barrel by fitting a 1mm spacer with a base gasket each side? This gets the transfer ports to more or less where they need to be, depending on a whole lot of other things. There is gains to be made by raising the transfers even more but you need to get the angles right as well, both up into the chamber and across the top of the piston. You will want to drop the bottom of the intake piston ports. Like I said previously I went way down and ended up with 200 degrees of port open time. The exhaust port I raised until it was open for a total of 200 degrees of crank rotation as well but looking back I think it was a bit much, though it did work well. Whatever you do you MUST NOT remove the bridge in the intake port. It provides critical support for the piston. When you drop the intake port down reduce the width of the parts you extend down. This has a couple of advantages - more support for the piston and doesn't increase the cross-section of the port and more than neccessary. You have to plan and measure everything you do. Remember that if you raise the exhaust port too far and drop the barrel to fix it you will be extending the intake timing which could be another problem if you have already got that all ported. Devcon can be used in the intake of course to fix stuffups. There are so many variables you could write a book. You'll need a protractor to put on the end of the crank so you can measure crank angles when the ports open and close. Don't tune for more than 11,000rpm on the TS engine and get some C3 main bearings. I think the best pistons are the RG400 rear cylinder ones, they have thinner rings and are just a nicer piston. As an experiment you can file a bit off the bottom of the piston on the intake side to extend port timing. If it doesn't work a new piston fixes the problem. The chamber will need to be machined as well, and the top of the barrel. Like I said you will need a plan BEFORE you start. You need to measure everything BEFORE you start to make the plan.

A few more things - I used to polish the edges of the cutaway under the gudgeon pin on the piston to reduce stress raisers to try and reduce cracking, it seemed to work. I also filed all the little bumps off the top of the piston and then polished it with wet and dry till it was nearly a mirror finish. I had a theory about that and it seemed to work. Once you start taking the squish clearance down to where it should be you will need to dowel the head to the barrel so that the chamber lines up with the bore. It's quite tricky getting it all clocked up for machining but it's got to be done. I think Pete Sales actually made a tool that allowed him to cut the squish with the head bolted to the barrel so it was perfect. Don't make the exhaust port much wider than it already is and don't raise it too much. it'll kill the motor.

Sweet,

I am using a copy of Berts barrel

So tired cant eventhink of anything to right

sorry I have to go back and play Moto GP 4 I'm addicted

Great post Speedpro, that's the info that all of us TF builders need.

Ivan, I'm sure that Barrel was done by PS.
it was off one of Ray Wilsons toys, that was a rocket. so I hope it all go's well.
Don't forget the base spacer. I've got one up here if you need it to copy. or if i find some time over easter I might do it for you.
and
well if you stuff it up, you would have learnt something.
STOP PLAYING COMPUTER GAMES !!!!!!! read a book.

Ray Wilson - yeah his bucket went OK, had about 16-17hp I think. Mine made 19.9hp with a big FAT powerband. Just for info!! Not showing of or nothin'.

hey first time back on kiwibiker since I am now 125 GP and 250 GP world champion:Punk:, sweet I need to get the right kind ok card to map the barrel you gave me thenstick it in to myne tape it there and feep taking metal off the barrel until they match,

How did you get 19.5 hp

Not quite sure what this means but i figure that you are working on your new barrel ? :thud:

build a good zorst, that suits the porting and power range that you want.

VERY carefully and over a few years, by feeding pistons to it and working on the crank. Like I said - You have to have a target and a plan that will get you there. EVERYthing must be to achieve that target. I think I had over 140 dyno runs on that motor.

Don't try copying a barrel using tape to transfer the port dimensions, it isn't accurate enough and only takes into account heights, when angles are critical as well. You have to assemble your motor and measure what you have and then mark the height of the ports where you want to take them with all the base gaskets/spacers in place. You rotate the crank to the right place, lock it and then scribe across the top edge of the piston onto the barrel over the ports. Make sure you measure using the piston type you are going to build the motor with as there are minor differences in heights. The only way to do the intake port is trial and error. Take some alloy out, assemble it, measure it, disassemble it, do it over till it's right. You are not going to do a good job in a weekend. It takes me a whole day just to get the combustion chamber shape and the compression right.

The whole exhaust port, because it curves, is going to take a lot of careful work with the dremel and finishing with coarse W&D paper.

A real good thing to do is rebalance the crank as they vibrate real bad. Either side of the big end pin hole in the crank webs is a hole. Press a slug of aluminium into the big hole only on both webs. The differance is amazing. While you have the crank apart put a rod kit in or at least a fresh bigend bearing and thrust washers. The good thing is that all the TS rod kit parts have been superseded by RM parts.

My current MB100 made 22.5rwhp when it was fresh. Again with a BIG FAT powerband, and reliable as anything. Nigel Duff's RG100 makes 27.5rwhp and it's got a HUGE FAT powerband but that has had mega hours spent on it and is very very trick inside.

es I am mapping the ports in your cylinder and then basically transfering them over to my cylinder and do some angles for the ports and then I am done:2thumbsup

[/QUOTE] build a good zorst, that suits the porting and power range that you want.[/QUOTE]

Yeah I would want quite a Snappy power band like my RS125 so I need to ride the thing alot harder.
