  1. Grizzly Engine & Transmission

  2. Grizzly Engine & Transmission
    My 07 grizzly 700 dies at random times while riding. Used to happen only after riding awhile when it was hot but now it happens whenever. It will start to lose power like you shut the key off and start backfiring and usually start to come back to life and run fine for awhile then start again...

    Hey gang. New user here. I'm having a new problem with my 2002 Grizzly 660 where it will start and run great cold, then when it is warmed up and idling, it will sputter and die. Then it will be very difficult to restart. I have read about the vapor lock/fuel boiling issue now and did a...
