I am once again having idle issues and would like to seek advice here as I have little confidence in the dealer sorting this out.
Bike will run great for hours and then out of nowhere lose its ability to idle when I engage the clutch and am downshifting to stop. Typically I can downshift to 1st gear and near my stop when the rpms drop below 700 and then dies. I can restart the bike easily and it will immediately go back to running fine until some random stop where the same pattern repeats itself with the idle dropping and the bike dying. Very annoying when attempting a slow rolling turn when the bike dies mid-turn.
Yesterday I hooked up my computer to the OBD connector and observed everything through the software I have (Dealer Tools, company from the UK that provides ODB connector and software for the Rocket). The Primary TPS was at .614 volts (new primary tps installed last summer) however the secondary TPS was at .483 volts and fluctuating slightly while the bike was running at idle. Bike idled nicely at 800 rpms for about 6 minutes and then exhibited the idle problem and stalled out. While going through stall out process both TPS voltage values fluctuated quite a bit with the secondary TPS dropping to .241 volts. I will add that the battery voltage was fluctuating between 11.2 volts and 14.3 volts through all of this (is this normal for an idling bike?) So with all of that said, can anyone point me at what they believe the problem is and how best to troubleshoot further? I am thinking either secondary TPS is bad or bad electrical connections causing voltage fluctuation. I have several after market items hooked up to an Eastern Beaver PC8 (GPS, Cell Phone mount and charger, Stiebel air horn and lights) Any assistance would be appreciated.
Bike is a 2005 Standard with triple K&Ns, secondaries removed, Predator pipes, PCIII mapped for the bike setup, O2 sensor removed.
