have read numerous threads on efi tuners.. ied's, tfi and pcv as just a few examples but no one mentions if running one with a stock exhaust will cause a short life span for the cat. since it's running richer wouldn't it soot up and clog the cat?
wouldn't more fuel stop a lean mix which makes bike run hot? wasn't concerned about the temp as i would think it should actually drop at the expense of creating soot. hmmmm.... am i way off?
No Cat is short for catalyst other wise known as the third part ( ingredient). The material in the CAT reacts with the unburnt fuel ,exhaust and air to burn off unwanted emission. It works ok as long as it does not become clodded with soot or to much unburn fuel it that happens it begin to run hotter and hotter until fails. Of it plugs up and restricts exhaust flow causing other engine parts to fail.
Of course this is the short version but covers it pretty much.
thanks... that explains a lot... reacts with fuel to help burn it off. makes sense.. so in short if i want my bike to run cooler and pretty much stay stock i still have to remove the cat and get a tfi.
