I went to fire up my 02 Rev3 270 and had no spark. Just for background the bike has run great. Ran it a week ago and turn it off. About 2 months ago I put in a new stator because I buggered it up taking off the flywheel.

So here's what I've done so far.

No spark a the spark plug.

No spark from sparkplug wire. no power out of coil

Checked the red wire coming out of the store. Power coming out of there.

Checked the wires that plug into the coil. Just barely a reading on the volt meter.

I called Beta USA and they said it might be the black box as they hardly ever seen a coil go bad.

I disconected the kill switch to see if it was maybe stuck and grounding it out but it didn't make a differance.

Anyone have any other ideas for me to check out before I put out the $$ for a black box?

Thanks Guys and Gals,

Greg

Had the same sort of problem with my sons Beta, spoke to Beta UK (John lampkin)they sold me a CDI unit (black box) with the proviso that if it did not fix the problem I could return it no problem. Maybe Beta USA might do the same. By the way it did fix the problem.
