Don't know. I doubt it's been done as the RD engine wasn't the best out there. I've heard quite a few stories of the unreliability and awful fuel consumtion from the RD500. I should think the engine is way too wide to be honest, and the carbs are mounted on the sides too.

Doesn't stop me wanting one mind...

Why not get a TYGA 300cc kit instead?
