Bike runs great but when I pull clutch lever and put into first gear it kills the bike have tested side stand switch and clutch lever switch and all seems to be working fine currently chain is of bike waiting for replacement to arrive.When I engage 1st gear front sprocket turns abit before stalling I’m guessing bike would lurch forward if chain was on before stalling any ideas thanks
Bought my first bike not that long ago and the bike started having problems a few weeks ago, it would randomly stall when taking off and then after stalling it would have great difficulty starting again. It started with a sudden surge drop in power for a few seconds then gained power again as I was a few meters from my driveway and then the next day it stalled on the main road and kept stalling when putting it in gear. I ended taking it to a mechanic around perth who had a diagnostic tool. They had a look at it and replaced the spark plugs, fixed a couple serrated wires at the back, did an oil change, adjusted the throttle cable and reset the ecu. I bought it back home and ended up installing a new after market fuel pump after still having trouble with it starting. That seemed to fix the problem and it idles perfectly now at a cold startup. But now after taking off and revving it a bit, it stalls basically whenever I let go of the throttle at a stop or holding the clutch to downshift. Even at idle I can rev it up a bit at a cold start and it will idle back down fine without stalling but as soon as it runs for a bit it stalls when I let go of the throttle. I had a look at the TPS (Throttle positioning sensor) and it read 3 and half volts or something when it was cold and it read 1.31v right after running it hot.
Here’s a couple videos of it running and stalling
Just wondering if anybody has any idea as to what the problem could be?
