Convert 250mxc to 300

Recommended Posts

Hey, i have a 2000 250 mxc and absolutely decimated the top and bottom end, crank needle bearings blow past the piston and sand blasted my piston and jug... Catastrophic failure... So i was wondering if anyone would know if i can buy a 300 jug and/or sleeve and bolt it to my 250 bottom end??? If so which parts would i need??? Love the bike and always love more power...

On your bike the 300 has a different crank. You would need that as well.

Think crank, cylinder, powervalve stuff, head.

If i recall the cases were the same between the 250,300,380 back then.
