Ok i found an ad for a 1989 kawasaki kss 250A four wheeler racing bike. it has a DOCH engine.
does any one know what it is

 

It might be a typo. I would call and ask your Kawasaki dealer but I have never heard of or seen anything that would match up with that model. If it is a DOHC motor and it is 250cc my guess would be that it is a ksf-250a AKA Mojave.

 

I agree with you TeamGreen with DOHC an abbreviation for Dual Over-Head Cam quite possibly.

 

Well Bud,

I can almost promise you that what you have is a typo. It has to be a ksf mojave 250A. I own one just like it. Same year model and everything. Not a bad bike.

01 Raptor on the way.

 

thank you all for clearing that up
