hey i have an '88 230 quadsport (clutch, kickstart) and i was wondering how the hi po carb and manifold from vince's cycle perform and if anyone has any other suggestions for a good carb and manifold. also vince's cycle sells a hi po exhaust (headpipe and muffler) and was wondering if anyone knew anything about that. and if anyone had any suggestions for a head pipe on my bike. thanx.
