    I have tried my best to troubleshoot here’s what I’ve done so far

    Replaced fuel pump/fuel filter/checked pressure 45psi
    Pulled injector and cleaned
    Replaced intake boot
    Checked valves and shimmed to spec .004-.006 intake and .006-.008 exhaust
    New spark plug

    I’ve looked through the forums and someone with a similar problem mentioned replacing the coolant temperature sensor.

    Has it ever been adjusted with ibeat? Just after I got mine I was dealing with the same thing. I had Dan at motoxotica adjust it and all bogs went away.

    no I’ve never had it adjusted with ibeat. I did the dealer supplied power up and it’s ran fine ever since so I don’t know what could have changed. I’ll look into taking it in for a remap. Is there any way to bench test the coolant temperature sensor?

    I finally got an Ibeat setup and messed around with the co settings and was able to fix the problem. Thanks 268fords for pointing me in that direction.

    Good deal. Glad you were able to get it figured out.

    Hello, I have a similar problem with my 08 te510. I bought the bike without an O2 sensor (it has a black in it), does this mean I will struggle to amend/adjust things in Ibeat? I have the Ibeat software but the TPS and CO settings and greyed out.

    The TPS show 908 ? and the CO are already set at 110, 110 & 100.

    The bike is stock apart from the o2 sensor blank.

    Any help that would be appreciated

    The bike was meant to be ran without the lamda probe(02 sensor). They were sold with the probe to meet federal emissions and after the initial 500 mile brake in period, it was to be removed and the jumper plug was to be installed in the harness to put the bike into race mode. With the lamda probe installed, the echo cut the power in half. The lamda probe doesn’t work like a traditional 02 sensor, in that it’s range of adjusting a/fr is very limited. I have never messed with ibeat personally, but watched my bike get setup about 10 years ago.

    Great thank you, I will see if anyone can give any pointers on using iBeat and give it another go.
