Raise needle, richer pilot) and I have already tried brand new spare plug but no change. EDIT: one thing i noticed is...

    @Larry's Shee Might this all be caused by air leak at the exhaust flange ? I installed brand new fmf fatty with silencer but I was surprised that there is no O ring on the exhaust flange slip on part. There is unburnt oil all around the flange. Im thinking on just welding the flange onto the pipe

    Im still struggling with the auto ignition the harder You ride it the higher the idle gets and eventually starts dieseling. I have done leakdown test again and it shows no leakage from seals or gaskets anywhere. Only thing i havent tested for air leaks is top cap on carb... Will try that next.

    I have dismantled top end and currently redoing hemi to about 20cc's to drop down the comp. The squish part was cut at 11 degrees and confirmed its all pretty much the same towards the center(measured with solder at the side of the piston). Havent done a plug chop but will do it when I put it...

    Hello Larry! Please read bottom part carefully - I mentioned all those things. As for the 18cc head thats what i basically came up to when I cut the dome and after reading about head rechambering I shouls be ok with 98 gasoline at 160 psi comp. And yes leakdown test was done and retorque too...

    Help needed: Am I running too lean ?

    Hello, basically I did the 18cc hemi head mod, porting from KOR videos, airbox lid off, 1mm exhaust port raise mod on an otherwise stock blaster. I installed 260 main and did the break in but after opening throttle I think I can hear loud pinging on higher rpm's and on top of that after I come...
