I'm in the middle of my drag bike build... And I tried to throw an engine (Briggs 5hp flatty) together with some aftermarket and it just isn't working. I plan on running a mikuni 22mm 94ss cam, 1.4 springs and a billet rod with a stock raptor flywheel.. Does this sound like a good combo? Should I be running a pump?!? help me out here guys. Thanks a bunch
