1. check the switch contact of the front brake… when you press and release, you should hear a ‘tik tik’ sound.. if not, the switch is broken… replace it.
2. about throttle matter, check cable and where the cable goes into the carb, might be some pin or spring prob, i bet on that.
3.about the turn signals, might be the current, imean its an aftermarket stuff and the electrical components in it is definitely not the same compared to stock.
(the guy above put 3 twice )
4.about bike jurking, ok for downshifting and letting clutch too early BUT, check the bearings where the forks connects to the chassis. you know what i mean ‘coz i can’t explain the area well.
check these and lemme no…
