Buell blast is backfiring. Sat for 2 years so, cleaned fuel tank and cleaned carb. It will start now but is backfiring and will die of I try to idle. Thanks
If you did not completely disassemble the carb and remove all jets/emulsion tubes/needle valves then you did not clean the carb adequately. You could try adding either Seafoam, the Yamaha CARB-CL-EAN-ER, or Techron fuel system cleaner in an auxiliary gas tank and running the engine for a short while to ensure the mix gets into all the nooks and crannies. Let it sit for a couple hours to do the work, then drain out the float bowl, hook up the bike's gas tank and see what happens. Otherwise you need to remove, strip, clean, reassemble, and reinstall the carb.
