I just bought my youngest a really clean 2003 Kawasaki KFX50 2 stroke. I have performed some routine maintenance and removed the oil injection in favor of premix. Now I wish to change the gear oil and need to know what type gear lube Kawasaki/Suzuki calls for. I do not have the owners manual and am hoping someone can provide that information for me.
Thanks

 

I'm sure that a 80 weight gear oil would be fine.
FYI: you have yourself a Kymco and it's a fine machine.

 

LT80,
Thanks for the information; was going to use 80 weight Hypoid gear oil but thought I read somewhere they recommended 10W30 engine oil.
Do you have any suggestions on where to get a larger main jet for this quad?

 

I've used 10-40 for years but I may change it more often.
Most all will say a hypoid is better and they are correct.
Most any dealer/bike shop has jets but you would need to take your current jet/carb in to get the correct one.
Talk to a guy called " Airmobile101" He knows alot about this machine.

 

Cool, thanks for the information.
