rough idle : V-Twin Forum: Harley Davidson Forums

I have a 63 xlch and ever since this spring started I can't seem to get it to run right. When it is idleing it a loud smacking noise like a backfire but not as poppy of a backfire that I am used to. Then it will stall out with a lurch when its in neutral. This is my first bike so I don't know a whole lot, easy fix or should i find some help? Thanks.

I would certainly check for air leaks. There are gaskets and seals in there between the carburetor and manifold and again beween the manifold and the cylinder heads.
