The bike starts up great and idles perfectly, it has plenty of power on acceleration but when it is at a constant throttle position it stutters and bucks like its running out of fuel, it also backfires. It is especially noticeable on the street but off road as well.
I read up on this problem extensivly and have disconnected the TPS and it did nothing. I gave up and brought it to a shop and they rebuilt the carb and also found the spark plug to be VERY black, that was replaced and it is still doing the exact same thing. Any other idea's on what is causing this problem? Bad coil or ECU maybe is what the shop is saying but he seems semi clueless? Thanks so much, I bought this bike for its reliability and have not even got to enjoy it yet
