Hello, first Yamaha quad and I have looked on U-Tube for this info and couldn't find it.

I just bought two Wolverine 350 4x4's and one of them is bogging out @ full throttle.
Not sure if it is the carb or the emergency brake rpm cut out.
Replaced the plug and the problem has not gone away.
Running Premium gas since they have sat for a year.
Cranks up on the second pull w/the choke pulled out (need a battery).

Here are some videos, one a question the other to show how it is cutting out.


Thanks for the help,
Jim

 

Did you ever figure this out?

 

I'd imagine its the carb since its cutting out at full throttle and not all the time. You could always bypass that e-brake switch to double check before tearing into the carb to be sure though.

 

Sounds like fuel starvation...if it cuts out every time you give full throttle (regardless of gear/speed) then it's a carb/air issue.


Put the rear up on a milk crate and run it without load...does it still cut out at full throttle?
