Today I just ordered about $60 (would be more like $75 retail) from www.bikebandit.com, they give some decent discounts and have no minimum spending amount. ;)
The Ron Ayers site, you have to have the part numbers and then enter them in the search. They come up. It is about 10-20% cheaper than the honda-kawasaki site.
Jeezus...I just checked prices with bikebandit vs ronayers, the left power valve at RA was almost $10 cheaper!!! I'm gonna go cancel my order now...thanks matt, didn't even see the part search. :) :) :)
Hey check out Frpoffroad.com. Its a fairly new site but its Jeff Fredettes company and you can get anything for your kdx that you need. He ships parts really fast too.
