Having trouble with spark; plug is new, correct gap; new stator; good coil but my flywheel is very sus so i'm waiting on a replacement one. Any ideas where to start? i'm going to check a few electrical components against values in the book and see if anything is dead; hoping the CDI isn't garbage.

Hi mate,the bike is looking great.Its hard to see in your pictures, after you had the frame painted did you grind off the paint where the coil mounts on the frame?

He would also need to grind off the paint where the engine mounts, or run a wire from the coil to the cylinder...

dang, new coil didnt help any; picked up an OEM stator to replace my aftermarket one, thinking this might be the issue since everybody i talk to has bad experiences with aftermarket stators.

if not, then i guess its the ECU

we'll know in a few days.

Have you checked the kill switch? Sometimes a man can overlook the simple things, me included.

Rode one of the local tracks a couple saturdays ago and bike performed awesome.

Couple adjustments to the controls, but the carb was spot on and suspension was right where i wanted it.

Couldnt ask for more, hoping to get a few more rides in but weather is going shit quick; probably spring time.
