ARgh.. lost what i typed out.

Thanks again everyone.

You are right Dave, bigger bike is better value. Its on the cards at some stage- I have had faster previously and my dream bike is probably an RS250 :-D

The guys I ride with all have very small capacity bikes- It would actually be less fun having something that got from a-b without a screaming panic. At this stage its quicker than a px200 vespa and a few a100's (and similar yamaha thing)

but those bikes are always getting faster.

Actually used one of your old posts (in another thread) to choose spark plugs earlier today, Dave.

Who's your crew? Should jump on my wifes GN250 (if I ever get it running right) and join yas for a blat.

Look I used to ride a lot of ks on an RG50 despite an 1100 in the garage.
I did 6 cold kiwis on one. Small bikes are cool.

And there's a fair few spare MB parts in case of a racing return.
But,

i have no idea why its referred to as a 115cc kit by my maths it would be over 125cc

Malcom bought one. Not sure if he used it but wasn't super happy with it, at least for a racing bassis. From memory the transfers were a little thin.

Remember I will send yo one for free Dude cheaper........
As for the pipe make one yourself.
20 Gauge mild steel.
go into mico metals and get some 75mm or 100mm thin wall irrigation pipe for the slenncer. Or free if you know a market gardener.
I am happy to do a quick and nasty design for a stock cylinder and big carb and reed combo. But mikes will have access to better.
Almost anything will be better than stock.
But as i said Try and convince Speedpro to do a cylinder for you to suit he has vast experience in what works and what doesnt. Its very easy for someone not experienced to make it go slower.
Mikes basic combo would double your power out put to 20 hp or a bit more.
His full house race bike was over 3x stock.

Was it plated Dave?
From what i have seen in the pics i agree with transfer shape and width.
But theres no replacement for displacement as the yanks say.
Also i doubt there is many left in the worldand i cant see anymore getting made but pistons are available and single ring.
So if he wants one i would suggest he buys one now before they all disappear.
Also the durations from what has been written std are incredibly mild i think more cooking than the H100 even.
I have not seen Koba post for ages is he sprogging or something..

KT100 bits go straight in. Pistons start at 52mm and are single ring. You could even have the crank rebuilt using all KT100 bits. Not sure on availability due to changes in karting. The deck height will need adjusting. If you lean on it even a little bit with compression and revs you will need an adjustable ignition. Ignitech is definitely the go and can obviously be transferred to the next bike if required. My Ignitech is now in my 4T scooter. An Ignitech system is a very good investment. Get a 2 channel DC CDI system. I only use one channel but could double them up but haven't seen the need. A built crank should be good for 14,000rpm but 12,000 should be plenty on the street.

Don't think it was plated, wasn't that long ago. He's running wgtn racing now in between being overseas.

Yeah KT piston skim the barrel top as shorter but cheap and great quality.
