115 Yamaha running rough

[sidelock]

I mentioned in my original post that the technition at Bass Pro pulled the carbs disassembled and cleaned them last fall. Having said that while visiting Harkers IslandI last fall I brought up the issue with a Yamaha dealer while buying Yamalube and he stated that the holes in the small jets are so tiny, sometimes cleaning them just won't cut it and they may need replacing.

You may be able to unplug them with small wires. I once had a car with a 2 barrel Holley, and the idle air bleeds on top of the carb were so small that about every 6 weeks I had to spray the top of the carb with Gumout to get it to idle smoothly! Finally changed manifold and installed a 4 barrel Carter Thermoquad and eliminated the problem while also improving gas mileage and power! The racers love Holleys but I've found them to be pretty temperamental for daily street use.
