My son recently crashed his pw 50... he's ok just had a bruise, however he snapped his on off switch, I went to see my local yamaha dealer to order a new one, it had to be back ordered... they can't give me a solid answer of when it will be in, I want him to be riding now, anyone have any ideas of how i can make this thing work I would greatly appreciate the advise, thanks!
