Tindy, I don't want to scare you but......
That is the sign that your axles are popping out, it means the Circlip for the CV joint is working loose!!
part numbers for the upgraded replacement clips is 5km-2536e-10
do a search on axie, axle and popping on this site.
This happened to me 4 times and many times to Bonez5 and others!
Yamaha should repair under warranty! they did mine more than 6 months after my warranty was over!!
