High idle and slight backfire when hot

PostAuthor: Shawnkva » Sun Jun 02, 2019 9:04 pm

1995 XV1100. I just cleaned the carbs and set the floats. Installed new carb boots too because it ran like it had a vacuum leak last season. Replaced a few questionable vacuum lines, new air filter, oil filter and fresh oil. Starts right up with a half choke and I can take it off choke in just a few seconds. It runs great and pulls hard until it gets hot. After a few miles, it wants to idle high and backfires on occasion while sitting at a light. The PO put some after market pipes on it. No idea what brand. It has stock jets in the carbs. Could this be the issue? I would rather find some stock pipes than to pull the carbs again if that's the case.

My first thought would be a vacuum leak. Backfiring is a sign of running lean.

Have you looked at the plugs? Usually this will give you a good idea of what's going on. Sounds lean to me.
