What do you think this Testing out the MPG-38 engine with 17mm carburetor video?
Fred from CR Machine takes the trail bike into the snowy, wet woods during spring thaw. Testing out the performance of the “Hammer Junior” intake manifold and 17mm PHBG carburetor. The engine is restricted by the unmodified stock exhaust muffler. Performance seemed slightly better than the stock intake/carb setup.
