175 main, 68S Pilot and B53E needle - They sell the intake boot for the carb and you are going to want to drill out the baffle. That would be a good start.

Yeah thats close. You need to make sure that you get that new intake manifold. Basically it is the rubber boot between the carb and the engine. The HRC boot is wide open and the stock has a small hole and is very restrictive. There are also two boots on the airbox that need removed. You should really check out http://www.xr650r.us/
