Hi all, i want to know a little bit more about the runner's rear wheel system. Now i'm thinking to make my Gilera stalker a real stunt toy, i have got already the engine, it's 150cc air cooled from Aprilia SR but the latest model with clutch's nut outside the variator case, i'll put my old Malossi 172 cylinder, multivar and delta clutch and here we go

but the only thing that's bothering me is the rear drum brake, the engine is "prepared" for the disk brake by the manifacture, there is the two little holes (sorry but i don't know the word) on the case and all i need is the wheel with support and disk from runner and the brake calipper. I have one old runner engine here with all this stuff but it's 50cc model, can you tell me can i put the wheel with calipper etc etc to the SR's engine or not ? 10x in advance
