Manifold

[cape tod]

I have a bike a stock manifold will not fit .I have one Zig zag. It faced down leaked fuel.I chopped it and now is even with a small down pitch coming in sideways. It runs better but will not hold consistent idle.can it be too long.

more likely an air leak - but if motor has not run in yet, it may smooth out later
