Hi all. I have recently acquired a set of 78-79 carburetors and installed on my 71 XS1B. I want to replace my old original holders with a new K&L set. Can I use the stock 71-73 style or do I need to change to the later 74-77 angled style. The carburetors seem to fit into the stock original holders and the bike runs, but when the engine got warm, the idle started to oscillate up and down, so I am thinking its an air leak once warm.
