Post by bert4246 »

Hi all just purchased 98 firestorm and seem to be getting a misfire when holding revs bike pulls well but when holding constant revs it seems to misfire and I can feel it through the tank changed plugs and filter balanced and cleaned carbs but problem persists could this be a problem with coils and leads thanks in advance bert

Sounds like Carb Fart, they all do it to a certain extent, basicaly a backfire through the carbs into the airbox.

Check your TPS setting with a meter & try to get it adjusted to as close to 500 omh's as poss.
