2021 250r wouldnt start yesterday. We unplugged the killswitch/mapping switch and it started and ran fine. Is there any way to fix the current switch or do i just need to buy a new one. Also is this a common problem, or something i can avoid some way?

Welcome to the site !!

I am guessing you washed the bike and got the switch wet and it shorted out ... usually the cause ... and yes that is a common issue ...

Only solution is to replace it as it is internally shorted , most likely if water was the cause ...

Avoid ..... washing the kill switch , I usually wrap a 1 gallon Zip-Lok bag over the end of the grip/bar , to cover it and use a long garbage bag tie to seal it off , then wash away , ... I also just wash everything else and leave that part and wash it by hand with a toothbrush and some cleaner , and I ALWAYS blow the switches off with air before attempting to start the bike , as that is when it will short out , is when you crank it and the circuit board is wet ... but yea , a dirt bike you can't get wet ..... all the electronics make the bike better , but make everything else worse ...like washing the bike ..

thanls, i figured, the weird part was that i didnt crash that day and had already done one moto before that. thought it was a fouled plug at first but it ended up being th4e killswitch, ordered a new one, and ill just stall it for this weekend

Yea , Like I mentioned , all the electronics make the bikes nicer , but also makes for a pain when something goes wrong ...

Hopefully the new switch fixes it ...
