310R popping & hard start

I'll give a few quick answers: TPS at full throttle should be in the 3900ohm neighborhood (so look hard here; also make sure you measure the correct 2 wires), 700 ohms is good for closed throttle. Injector resistance is 10 or 11 ohms... I think you're okay with 9ohms. Coil primary resistance sounds fine; also there are not many reports of the stick coil failing. Speaking of coils, the pick-up coil can go intermittent on our bikes and are not available separate from the stator (sometimes you can find them aftermarket though)- and they do cause a lot of weird voodoo.

hot idle should be 2000+ rpms. Adjust as necessary

This thread is kinda old now, and you never really answered any questions about the history or solutions.... why don't you start a new thread with a description of your current problems.

good luck.
