The extra length on intake is so carb can be mounted at all, steep seat tube short frame, throws throttle cable into top tube, no air filter fits. Is what it is. I beat up on it till I had it right, there is no leaking now. But it may have leaked before I redid it with a clamshell coupler.The extra length on the intake isn't going to affect any of that. Mount your carb directly to the black intake and eliminate the hose and clamps. All that stuff just makes it easier the get an air leak.
I was more curious with exhaust length at this point. But there is some science to intake runner length too, longer for low rpm shorter for high.
Anyways...will that pipe overheat head if I get it puking rich, and work backwards to tune it while doing breakin?
