Ok, so I have been having issues with what seems like a fuel problem but am curious to whether it could electrical. What would happen was that the bike on choke at any position would not run well and I would have to ride for 10mins after initial warm up to get rid of a backfire/popping off idle. I've had everything done to the carb just this last weekend(rebuilding for the third time,jetting, new intake gaskets). The bike ran great for only 3 days and now the same problems I had are now back. With the exception of replacing the carb there's nothing left on the fuel side so my question is could this be electrical? Even before going through the carb it would have days where it would run great but always no longer than a couple at best. The bike has a factory reman 80 with nothing special by way of exhaust, air cleaner, ignition.
