There is a down and dirty way to get a MM bike to run better by “ear” tuning the TP sensor.
While it definitely is NOT an authorized way to recalibrate EFI, it IS what we did to get the first MM bikes to run decently before there was any tuning devices available.
After the engine is completely warmed set the twist grip right off idle (lean sneezing) and adjust to TP sensor a bit each way until the engine speed smooths out.
It will be rich and lean in other locations but hopefully much better than it is now.
Note: Mark the sensor to the throttle body so, if you get way off base somehow, you can simply return to original setting.

Other than that, a proper tune with a Power Commander is the best resolve.

Thanks for the advice, I really appreciate all the input. I am going to try the tips reset soon and I am looking at the power commander v to try and cure the rest. I am missing riding, so I'll be doing this soon.
thanks for y'all share the wisdom.

Are the canned tunes good? Would I be better of getting a professional tune? After some research, I found a canned tune on the pc-v site for my setup?
thanks in advance.

If you put a map in and it doesn’t run like you feel it should you can take it to a qualified tuner in your area to get it done right.

Thanks Bob, there are not any dynos in the area. I would have to travel several hours to get that done. It is an option for sure.
I'm about to order a power commander from fuelmoto .soon as I can get the time, I'll make the suggested changes and keep my fingers crossed .
