Hello everybody I have to say this is a great site I havent rode on the dirt for a few years now and i cant take it anymore i need to ride. My question is does anyone know of were i can find a motor for a 89 xr600 or what motors will fit i just cant give up on this bike i rode it for about 12 years until my dumb ass brother managed to blow the motor and crack the block i have looked everywhere no one has one.thanks

Look on E-bay. They are on there from time to time. There was an xr650L engine on there a little while ago with a buy it now of like $450.00 which would fit with some mods and give you E-start. Complete xr600 engines are a little more rare but I am sure you could find one.

Remember that any year XR600 or any year XR650L motor should be able to mount up to your frame.

If the cases are cracked you may be better off just buying them (rather than a whole new engine) on ebay and putting your gears back into the new case.
