today i check the ignition coil, that is fine...
so i try to start up the engine. i kick start the bike, i saw there some gas fly out from the top cylinder air intake.(i left the gas tank and air intake off the bike.)
when the rpm get around 3000rpm and up, it firing sometime.
is it mean the gas too rich in the top cylinder??
if yes, how can i adjust the carburetor??


i find out what cause the error from my mc28
i forgot to plug in the throttle position sensor..
problem come again.
it start up, but when i try to start up the bike later time, i can't kick start it again.
so i try to push start it, it crank but not starting.
when i kick start the bike, i feel no compression on some of the kicks.
so i think, i need to have a compression test for it.
is there anything i have to check beside the compression??

by the way,what role is Woodruff Key?
i saw it in the tyga performance web page, it is high performance parts.
how i determinate which offset degree is good for my bike?
i know i have too many question, but please help.
thanks
