Well you posted this in the wrong section, and secondly how do you know it's clean?

What's the plug look like? Wierd that it would screw up in the mid range & not the top.

if it in the mid range .. most time it the needle not set right

plug is good but still replaced it with a new one.....now last weekend I blew a fuse, replaced it and now it won't start....got spark and fuel going in....wondering if it would be the timing or something else.....

Will it bump start?

haven't tried that was alone...I'll try tonight....what if it doesn't?? any idea what it could be??

Something electrical, starter, solenoid, the control module.

 

[pens3529]

is there any way of testing those so that I know what I need???

 

[pens3529]

found the trouble....it was te needle in my carb that was worn out so it would let to much fuel in at half throttle..but still need another carb for my bike to really work good
