ok, so first.... DONT .. i repeat DO NOT get the motocross poopoo pipe.
it is HORRIBLE! i had one, put it on... lost all tourqe, and top speed. And the back pressure blew out both seals. its only MAYBE 1/2" hose all the way thru.
to lap the head and jug top...
and watch the length of the spark plug. especially if your running a 40mm stroke engine. dont wanna smash the head off on first start
