Ok thanks guys will have a look at jets and see what can be done , also will dig sparkplug wire out and replace mine is glued on tight! hope i don't damage cdi, but got to be done .
Thanks for your help
Can't remember where I got it. I'm sure it was the cheapest POS chinese carp I could find. BUT, like I said, In almost six years and only God knows how many engine kits (60? 80?) I've only seen it twice.

Cool that is just like the one 'CDI' on my bike Al. i shall dig it!
just been reading on forum about '4 stroking' and taking in what you have all wrote taken carb off again , now I've taken more notice, looking down the inlet port, I turned crank to tdc shock!! theres alot of piston still showing! covering about 30%+ of the port!
Could i be suffering too rich mix' as this piston will not let the engine breathe fully? If only say 70% of air can get in and i have carb WOT sending 100% lots of fuel in 'richmix" that it can't burn?
Do you guys think this is most likely to be causing my trouble? and I should 'trim' file my piston first before any other adjustment ?
Thankyou for your help
Ok Jaguar thanks, i shall reduce the main jet size your link is great! i've read it more than once. My down pipe is now 6" longer and I have modded my stock muffler as in your diag'm, if i end up raising piston skirt 1.2mm i will also chamfer crown on transfer port areas 0.8 at 40deg. Yes i would like your cdi but can't afford it yet,
Thanks
