PW 50 Doesn’t Like to Get Wet

Every time my son's PW gets wet it won’t run past an idle. I am not sure what is getting wet or where I should start looking.

Thanks for your help. The little guy sure has a long face when his bike doesn’t run.

It is likely that the run/start switch wiring is wet. They are notorious for it. There is a flat white plug near the front number plate on the right side that has 4 wires, unplug it and it should run fine. The only issue will be that the bike will run and go in either the run or start position. The kill switch (off) will still work as designed.

The wires should dry out after a day or so and then you can plug the switch back in.

We disconnected the white wire on ours also.

Keep a check on the sparkplug cap. Riding through a puddle will soak the cap. Remove cap and dry by compressed air and you should be good to go.

Thanks for the pro-tips. Last time this happened we were stranded out on a trail and the boy was totally bummed. Would it be a problem to leave the white wire disconected all the time?

all the yamaha pw's were known for the spark plug cap being the culprit, one splash and they start missing, or quit. Replace it with an automotive style cap or wrap it in black tape. Should solve the problem.

for $8 at the local shop you can get a universal plug cap that actually has rubber on it and seals well. much better than the stock.

BTW, the dealer wants $24 for the stock one. No thanks
