Guys,
Ron has perfected the conversion process for the stem swap and spacer. He goes far beond of what your local machinist will do and for a much better price making it an unbelievable value.

Don't even think about it... just do it.

Has any one asked him about the wheel spacers to use a kdx front wheel? http://kdxrider.net/forums/viewtopic.php?t=9504

Ron is a member here...RBD ... you can also contact him through his website. Ron is a fantastic machinist and I am sure he would look into what you want done and quote you a price.

+1 on Ron's work. Did a great job on my KDX stuff, carb head and stem swap for the KX forks. He also machined the head on my KTM 300 to. Just a great guy to work with.

Well, the axle mod has been completed by RB. The parts fit great. All work is top notch. The 2000 kx forks that I have now accept a KDX wheel like it was meant to be there.

anyone know how tight the stem needs to be in the tripple clamp to require knurling? my cr125 tripple and kdx are exactly 30.17mm. it fits tight but do i need extra?

If you can tap it in with ease then it is probably too loose. If there is a slight press fit then you should be good. I don't belive that the tolerance is that critical. When the stem is in the lower clamp the snap ring will keep it from being pulled up thru the lower clamp and the preload will keep the stem tight in the clamps. The press fit of the lower bearing against the lower clamp is going to keep things in place as well. The forks will hold everything in place once the assembly is installed on the bike. To me a snug fit is good enough. a serious press fit would be nice but I don't think that it is that critical. As long as the stem isn't loose in the lower clamp then I would think that you should be good to go.

alright that what i was thinking. i sent rb an email about the spacer for the upper clamp and if knurling was needed. now all i got to do is find a lower bearing.
