Cdi issues

3 posts in this topic

I have an 08' yz 450. The bike would only run when cold and die when hot and would not start up until it cooled off. Then it got to where it had no spark period. So I bought a "good used" cdi box off ebay for $65 the bike now has a spark but dies when it gets hot again. Any suggestions before I dump $300 on a new OEM cdi?

Coil and stator is good hot and cold checked with multi meter

Carb is cleaned

New plug

That's kind of a classic set of symptoms for a bad stator, actually.  I suggest testing it while it's hot and refusing to start.
