I have an 1982 it465, I'm looking for more power / harder hit as in YZ 465. This bikes runs good, starts 3rd kick. I replaced the stock plastic with DC plastic (81 YZ) . The seat and tank are off a 82 YZ490. DG pipe and silencer. What mods should I do to this bike ? Or should I sell and look for a YZ465 ? If sold what would it be worth ? Thanks, Jay

The cylinder makes a huge difference but you have to change the timming to go with it. Also, a lighter YZ465 flywheel will give it more snap.

P.S. proper jetting is key to having a fast IT.

Isn't a wide ratio IT trans the same as a WR500? If I remember right the WR series stood for wide ratio. I planned on 2 more teeth on the rear sprocket. Jay

The only way to get the YZ(partially) is the close ratio gear box the YZ has, the spacing between gears makes alot of difference. The cylinder(ie port timing) will change power delivery but without the correct gearing power delivery will not be as strong due to the gap between gears.

Regarding the WR, yes it is a wide ratio like the IT.

You might consider buying a motor on evilbay(sorry, for some bizarre reason you can't say @bay!)

Not many open class bikes or parts around here. I'll probably find a YZ bottom end and build up a motor. The frame is a piece of cake to modify. The rear shock appears to be rebuilt already.

If you are interested i have a cylinder, head, right side case, tranny, and crank for it. As far as the cylinder goes i would try letting Eric gorr do some work on it along with the head.

What are you asking for your parts?
