Big bore for XR250?

Recommended Posts

Yeah, yeah, aside from an XR400 engine is there a cylinder/piston kit over 284ccs for the XR250? Right now I'm at 277cc and really need more but dont' want to sell my bike.

There are a few combinations with a stroker crank too.

To get in that 300cc range you're either going to be getting a new sleeve and case work, or you will be getting into the bottom end for crank work, or possibly both.

The TR 320 kit is high compression (13:1) and that complicates things for gas availability (100 octane).

The thumper racing 300cc kit can be done and the reliability of the motor is left intact. Can't say that for the other options mentioned.
