TPS. The throttle position sensor. TPS has an adjustment procedure.
Earlier models like the 650 have the sensor. Mine does this just a little bit so I know what your referring to. At some slower engine rpm and mph it will try to buck a little. like a lean or possibly rich mixture. My bike has been jetted.
It had stock jetting in it with cobra pipes. It did not buck at all.
but it ran so hot it would blister your leg on the rear pipe in a second.
Way overly hot. I did the RAK mod to the stock bagel, K&N filter,
117.5 main jets, Stock pilot jets and bumped the PMS screws out to 3.5 turns. It runs fine. but still does just a little bit of what your talking about. At around 20 mph. So the jetting could still be tweaked
a bit more to fine tune but does not bother me. when I get on it it flys like the wind. Highway speeds it's awesome.
