Hi everyone, I’m new here and new to 4 wheelers. Just got a Yamaha bear tracker 250 and joined here to see if I could get some help.
The motor runs and it drives if it up on jackstands but if you get on and try to ride it, it starts to drive but then quits after a foot or two and dies out and won’t drive. The guy I got it from said he was running and using it shifting through all the gears great and he started it up the next day and it started this.
He told me he thought it was the U joint on the driveshaft. He said it was probably worn and needed to be replaced.
I just finished pulling the swing arm and rear end assembly to check out the U joint and there’s no play in it. It’s tight and not nearly enough play to be loose enough to not catch and go.
Any ideas on what it could actually be?
Thanks
Timothy
