A friend has a 99 kawi 400 and wants to know what needles and jets he should have and what spring he should use in his clutch?

 

alba's jets for bikes w/ pipe and intake mods is around 20$

 

Go to the EPI website for spring info. The right springs will give a good gain. If your friend has no other mods he probably is okay with the stock jets. BTW - I know a guy down here that has a Supertrapp pipe and a jet kit for sale that fits the KVF 400 auto. $300

 

 

Thanks for the info i will see if hes interested in the pipe, and let you know.
