  1. Have you tightened your cam-chain? If it has slop in it, it might be throwing off your timming just a hair. Also check the fitting from your air box to carb. and spark plug gap.
  2. Any idea what causes back-firing and popping during engine braking? Also, my bike is hard to start when cold, I usually have to crack the throttle half way (then I let go) before kicking and it will take upwards of six kicks. Without the throttle blip, it will absolutely not start even with a hundred kicks. I installed a slip on Yoshi TRC silencer and after runnung it a bit the pipe was still a golden color indicating a rich setting, so I dropped the main down 5 mm and leaned the needle jet one notch. I've also tried the fuel air mixture at various settings and that doesn't seem to help. any thoughts or idea's would be appreciated.

    cam chain adjustment

    I went thru the owners manual a hundred times and could not find how to adjust the cam chain, only how to inspect it and disassemble it. Any help would be appreciated. I've heard it was easy and I know where the adjuster is - just don't know how to go about it. love the bike! love the power! best handling bike I've ever ridden!!

    not wanting to start

    I have an 05 and put a Yoshi pipe on it, changed the main jet from 165 (stock) to a 170 and now it's not starting worth a #$@*! it will eventually start with about fifteen kicks and about half throttle after afew backfires, any suggestions? I haven't checked the chain tension but figured that would not be it. any help would be appreciated p.s. it has always backfired when engine braking, even when it was running and starting good is this because the air/fuel is to rich?

    Need help.... LeoVince Pipe

    sorry your having problems, i read an article on the Leo pipe last year and it did say it was a bitch to install. they went on to say that you need to read the instructions very carefully and follow them to a tee even if you are an experienced mechanic---hope that helps! if not call LEo!
