My yamaha r1 keeps knocking its self off when i put it in gear and sometimes when i go over a bump i?

Question

i just put an undertray on it and prob moved a wire or loosend one i just dont know what one it is that keeps doin it

Answer 1

Sounds like the kickstand switch, you didn't have to relocate the spring on the stand when you put the undertail on did you? Either way, that is what it sounds like, simple test, locate the switch, it will be near the top base of the kickstand, it will have two wires running from it, and in and and out wire...cut them and splice them together so that it is by-passing the switch, see if that solves the problem.

Now, if it does solve the problem, REPLACE the switch and fix it right, don't ride it around spliced like that, a rider forgetting to put his kick stand up before taking off has seriously injured, and even killed quite a few riders, thats why all modern bikes have that switch.

Good luck!!!

Answer 2

If you mean turning itself off then you probably need to check your kickstand sensor.

Answer 3

kickstand sensor

Answer 4

For future reference, always give year, make, engine size and model # when asking questions. We need all of that info to give an informed answer.

Sometimes the year can make a difference.

Check the side stand switch.
