Barrel's away at the moment having a new coating, then a Wiseco piston in going in. I've been talked ito trying a 41mm carb aswell.

seems like your going two different directions with the flywheel weight and big carb! think the 92 kx5 have a pretty heavy flywheel for road racing already, the kx PV motor should have loads of low down power [compared to CR5] due to long stroke and KIPS, make sure you dont have any other issues with motor, ie leaking crankcases or carb problems
nice bike , good luck. i will try and go see u racing some time but most of the track seems to be a long way from LONDON
570mitch:
We have all different kinds of hill climb tracks in the UK, so you need a motor to suit fast tracks and tight twisty tracks. Benny Lindberg (Bempa) has talked of an adjustable kips also in his AF conversion document. It's going to be a year of trying different engine configurations.

I'm not sure about a 92, but my uncle put a 13 oz fww in his 91 and he is all smiles. I have a 11 oz in my 01 250, it defiantly improves traction. The snap is not as violent, and you have less wheel spin. Of course all my experience is on the dirt. Good luck.
570mitch:
Thanks for the info KTMdude, will take note and play around with these ideas. Next event has a flat out uphill finish in 5th, hoping to pull over 100mph with the new pipe. The bike handles much better now than in the old KX5 frame. Much stiffer but steering is really precise.
ktmdude:
I can't see in the pics if you run a steering damper or not. If you don't... you should. They improve your handling, the steering is much more precise. You will really appreciate it at high speed. Scotts are infinitely adjustable so you can play with at different tracks and conditions. I don't like riding without one. Check them out. I'm sure some of the guys on the circuit use them, ask them what they think. I don't know anyone that has ridden with one that didn't like them and what they do.
