Will 99 Cdi work on 89 motor?
Sharky74:
May buy an 88 Cdi and throw it in, as its all i need to make it run. The manual I have is showing 88 different from 89. Is this correct?
Foxx4Beaver:
you should just suck it up and contact alward25 and go this route!

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?

has the 89 got big or small flwheel?
on the manual it looks like 89 W/G white/green is the same as B/Y black yellow 90on
Sharky74:
It has the small flywheel, or so than the 99 one

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.

yes... :-)
and its only the crank weight. cases are the same ´89-2004 ..there are a few ways to change crank weight without modifying to the cases.. the added crank weight is caused on the fact that the big kx was used more for offroad then motocross since the early 90´s.
here is a hrc honda rc500 works-crank that was used in worlchampionchip
