2005 Grizzly 660 Backfiring and Incorrect Speed

Recommended Posts

Hi,

Have a 2005 grizzly 660. Just recently started backfiring and showing incorrect speed. Lifted seat and messed with wire going to starter relay, it stops for a bit but seems to come back.

I ended up pulling all the pins out of the connector for the relay and added new pin/connectors for all 4 wires. fixed it for a little bit but came back shortly after. This was a new starter relay i installed a few months ago. Anyone know if a bad starter relay would do this?

Hi @cliffyh I moved this out of the Yamaha Grizzly club forums to the main Yamaha ATV forums so more people would see it. Sounds like an electrical issue, is anything grounding out?

      I have a DS 650x available.  Garage kept for its entire life and runs well.  OMF beadlocked wheels.  Located in San Antonio Texas area.  I’m motivated to sell and work with shipping options but serious inquiries only interested in a large sport ATV that won’t come around again.
      Here’s a photo from a few weeks ago.  I can send over more photos, videos, or we can have a FaceTime session to take a look remotely.  Let me know.

      Let's just say there was a little fire on the old Griz and the carburetor didn't do too well. Is there an aftermarket carb on the market or do I have to go Yamaha to get this?
      Thanks in advance

      Got my Yamaha Grizzly buttoned up finally and went for a quick 2 hour ride in the power lines with my neighbor, who has a Yamaha Kodiak. We have access from his yard, which is nice. Was a beautiful day today to get out and will try to go more often. Ran into two other quad riders with a sportsman and I think grizzly. Also ran into a dirt bike rider. 😎

      Disconnected the plow yesterday on my 2004 Yamaha Grizzly 660 and am getting ready to do some riding yesterday and the battery went weak, Starter cranked a few times but week. Put my trickle charger on that I bought and went to the garage today to start it up, but the starter is just spinning and not engaging. The solenoid is clicking. The pull start sucks and is hard to pull (never use it and need to look into that). Quick video of the starter spinning. Could it be the starter or  the starter clutch one-way bearing? I guess I need to take the cover off to see what's going on.
