    04 xb12r sputtering at idle

    I bought this 04 buell xb12r the guy put an aftermarket exhaust on it which does not have the exhaust valve actuator, im not sure if all i need to do it take it to a shop and get the bike tuned. i put new plugs and a battery in the bike, just wondering if anyone else has had this issue. it only does it at idle and when im trying to maintain a speed.

    Whenever you put a new exhaust on, you need the corresponding map installed to get it to run properly. What exhaust is it?

    There is a sticky about this...

    You can:
    Buy an ECM from EBR or IDSpeed that has the correct program on it for $300

    Or PM AZMidget on here and he can install the correct program on your ECM for $100

    Or go to Buelltooth.com and see if they have it for free and do it yourself.

    Does your bike show a CEL?
    If not the ECM might have been programmed or you may already have a race ECM.
    You'll have to remove your front fairing to access the ECM. It will say "for race use only" if it's not the oem ECM.
    Also, I would check that you don't have an inake leak. It's a good idea to make sure your the bike is absolutely mechanically sound before you start tuning. Otherwise you'll be chasing your tail.
    Good luck

    okay got new intake gaskets installed, new spark plugs, and reset the TPS, but if the Rpm's are lower than 3000 it sputters and idles and still runs rich and backfires,how ever it is still a whole lot better. Also i have a new WISECO fuel tuner but i wanted to make sure it was running better.
