I know these are prone to go out and mine has I cannot find a replacement any where and i was wondering if a cdi of a dirtbike would work and what model it would be or a cdi off something else that would work? please help!

 

you can still buy them from Kawasaki (canada) $465.00 US +/-
1987 bayou 300 uses the same unit as the KLT 200 250 series machines, bike bandit has them as well
