The easiest and quickest fix is to swap the bits over from a crashed SP I would think. Or buy a new barrel from Honda and swap that.

So I can fit SP barrel on mine? SP's are rare in Vietnam. Mostly RR's. Can Tyga give me a quote on SP barrel plus the neccessary parts to make the conversion? Is there a big bore conversion for the RR?

The SP parts are the way to go... they are so bloody cheap in SE Asia anyway!

I've got a quote $200USD for the SP barrel. How much is it in Thailand? I really want to beat the SP club that laughed at my RR. Will someone in Thailand help me out?
