Will 99 Cdi work on 89 motor?

(1/3) > >>

Sharky74:
I bought an 89 motor to replace the one in my 99. Didn't come with a Cdi and I have my old Cdi. Will it work? Has the white/ green wire that is different, but didn't know if it was maybe just a ground.

My stator is toast so I can't just change it all out. Also, if it will not work, will one from an 88 (on my 89)work?

motopunk:
the 86-89 cdi´s will all work with the 89-stator.
 but why you dont use your complete 99 ignition system?  the only big difference between the engines is the heavier crank-weight that came in 92 that gives more torque ..

Motopunt I am still trying to figure out how the 92on had a heavier crank weight without modifing the cases, Any pictures of the heavier crank?

I think he is referring to the early years hole in the crank webs, vs the newer solid ones.

My stator on my 99 is toast. Crank bearing went out and vibrated out the stator mounting screws, ruining it. I have tried to find one ( stator alone) in the states but no luck so far.

I don't really want to upgrade to the $500+ one ,but may be a wise choice?
