Do you not have one ? or are thinking yours is bad. Open it and show me a pic, I'll show you what may be bad, and what you test and swap out. I've fixed a few ignitors in my time.

BTW people put GM ignitors in xs and kz's. These things aren't rocket science. You may be able to use any other ignitor off a different single bike or parts off a car that uses 1 per cyl.

Cool.

Turns over but no start may just be far simpler - fuel. Try with starting fluid.
Igniters control spark advance mainly.
In any case, the savage igniter is likely the simplest one on the planet. Its got a transistor that's gone to heaven, if it is even the igniter. Match the functions of the wires from donor to this one and you're good to use any ignitor literally. In fact I wont even hesitate to use 1/2 the ignitor off a 2 or a 4 cyl. Some 2 cyl's only have a single circuit one, they use wasted spark. As in at TDC both plugs fire, one at the top of the exhaust stroke and one at TDC in the compression making power.

Cool.
