Yamaha unveils the new YFZ450X
38MM Cast SmartCarb. Purchased a couple years ago for a yz250. Don't have the bike anymore, and it has been sitting around for about a year. Used, but in fine working condition. You can also purchase a different needle for different bikes, as well as rebuild kits from their website.
Asking $250 shipped to continental United States. I can arrange other shipping options at the buyers expense.
I got all of this stuff to make a second engine with electric start for my 2002 WR250F. Including complete electrical system.
The only things that are missing is the left side case, and a battery.
Included is a complete new valve train, and Hotcams. The valve seats were cut by my brother's shop, on a Newen machine, which is state of the art. I lapped the head on a granite surface plate - it's perfect.

If you're interested, we can get into detail about it. I'm a serious mechanic, and I was totally going to do this, but I got a big bonus, and bought a KTM EXC 350 instead. Check my posts and history on Thumper Talk.
