I JUST TOOK MY 2002 GRIZZ TO THE DEALER TO GET THE 20 HOUR SERVICE DONE. WHEN I GOT IT BACK IT KEPT CUTTING OUT AT ABOUT 25 MPH ALL THE WAY TO 37 IT WASN'T DOING THIS BEFORE WHAT COULD BE WRONG???

 

I would take it back to the dealer and say My grizz is cutting out at about 25MPH, and this all started when I picked it up from you after the 20 hour service date. This didn't happen befor I brought it here!
What are you gonna do about it?
Well just refraz that last part!
