It's still backfiring out of the 1 throttle body, just 1 backfire when I give it a fast twist from idle I think, haven't tried to reproduce it on the road, I'm leaning towards what I think atomsplitter said in the beginning, crankshaft position sensor, but it's not throwing any codes, I'm thinking ignition timing is just misfiring once in a while before the valve gets completely closed, I've looked in the parts dialog online and don't see a camshaft position sensor? Is there one? can someone please tell me how or what sensors are involved in ignition timing on a 2008 Triumph R3T. Thanks much appreciated, it's not all the time, just annoying when it does (popping) hoping it doesn't mess something else up, I'm gonna take the cam sensor out and clean it and the connections up like atom suggests, and maybe check the coil primary connections, again, did it about 10k miles ago. Doing all this cause I wanted to check everything out and hoping it's not a burnt valve or something wrong with the rings ie: broken, stuck, scored cylinder. Not burning oil, but a little low compression in one cylinder has got me worried, I have to ask the mechanic that had it if he did a leak down test, he found the low compression, next he should have done a leak down test would tell us a lot, I'll text him see if he can do it, definitely I'll do it before I start buying more sensors. Could be a head gasket. But I see no signs anywhere, outside is dry, nothing coming out the cooling overflow, no steam, no sign on plugs, nothing coming out the exhaust steam or smoke white or black, clear as the air going in. P.S. My new RamAir filter was shipped without oil, they do require oil right? I ordered some and cleaner the other day.
