After some serious porting on the intake I put a Walbro PZ carb on a 110 Kazuma engine and OH MAN! The performance is just outstanding! What I am looking for is an intake manifold that might have a straighter runner in it than the stock 110cc intake does. I can only open up the enterance to this intake. Its almost kind of "question mark:" shaped and I need something along the lines of a "L" shaped intake. Anyone know what applicaton I might be able to use for this?
