If you already know the part numbers for the parts you need, that will take a lot of work and guessing out of it.
I'd first try Jeff at
Z1 Enterprises
for the parts you need.
If Jeff doesn't have, or is unable to get what you need, then I'd suggest trying with
Cycle-Parts.com
.
They carry a pretty good supply of OEM parts, and are cheaper than what your local Kawi dealership would charge you. Keep in mind that Cycle-Parts.com has $75 minimum order though, so it would be best to figure out all that you need beforehand to see if it will reach the minimum.
There are quite a few other resources out there for parts, you just have to do some searching.
Try the
Parts Link
on this site. It has quite a few listings.
