  • problems with Backfires

    Hey guys well I ride a 99 kat 600cc everything on it is stock atm.. only thing aftermarket is a freeway blaster.. Anyway when i hit about 70-80mph my Tac sometimes will drop down too 0 and BOOM backfire and the tac shoots back up...now at first I thought it could be the Spark plugs but..then why would the tac drop..so im stuck wondering possible ignitation module? at lower speeds its fine..ive never had a backfire at 0-65 but as soon as i hit about 70-80 it pops sometimes.....mabye lose wire? any help would be appreicated.

      With or without religion, you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion.

          I haven't looked at the schematic but it sounds like the common denominator is the signal generator...
