1999 YZ125 mods

[dkortje]

I have a 1999 YZ125, racing C class motocross. The bike has suspension mods and an extra tooth on the rear sprocket. The rest is stock. Can anyone give me a good idea of what mods would be most beneficial for this bike. Thanks!

Keep fresh rings in it. They tend to wear a slot in them from the exhaust bridge. Boyson pro reeds are good as is a shorty muffler. A Noleen pipe adds a lot. Boy is still racing mine. :thumb:

? Noleen pipe. Have heard of them but don't see them in mags much. How do you get hold of them?

We get them from a local distributor here in Australia. I'm not sure for you in the States. Does Noleen still exist as the pipe is a few years old. Somebody should know.

try a search, i think there are quite a few old thread on how to make this bike rip! i think the V-force is a go idea.

I find the bike has a nice low end stock. My boy has a FMF fatty pipe with the Power Core silencer. I think you will find the stock reeds as good as the Boysens, although ours had the Boysens added. Look into "Crank Stuffers" for the crank.
I can't see needing much for this bike, especially racing C class. Save most of your money for the next ride.
Good Luck!
