2007 Yamaha YFZ 450 Backfire


Quad man34

Recommended Posts

I got a 2007 YFZ 450 I can get it to start off the starter it turns over by won’t fire and I have to push start it then it runs good but back fires when you let off the gas and then I let off the gas completely it shuts it’s self off so you think that I need new valves or adjust the valves

      This is something I'm extremely curious about. Has anyone ever attempted to buy a quad (or any other vehicle) from an impound lot? I've always wondered if this could be a bargain, or a waste of time. Google searches do turn up some helpful results. Looks like the state of NJ holds auctions online which I'd be a bit hesitant about.
       
      My online searches haven't really turned up any results of anyone buying an ATV this way. I'd be really curious if anyone tried this, or knows someone who has. I've actually found a couple pages with online auctions for my state, but none had ATVs.

      2022 Sector 550, 414 miles on it and the gas gauge reads empty.  I topped off the gas and it didn't change.
      There is no fuse that I could find.  No access at the gauge cluster.
      Wiring on the top of the tank looks good, properly connected.
      Could the sending unit in the tank be stuck or broken?
      Has anybody removed the tank lid?  Any tricks?  
      Any other ideas?
      Thanks for any help,
      Clyde

      Hello there
      I'm having a problem finding a quality carburetor for a 1993 Suzuki Quad Runner lt-f 250 2x4. I find a lot that have 3-4 star ratings. And all so far don't have the right throttle Cable inlet at the top. The last one I got 4 star on Amazon has a threaded cable sheath rest that could be partially drilled to work. I would prefer to get one I don't have to modify. Any recommendations are greatly appreciated!

      I just bought two 2002 Suzuki LT80K. Do I need to mix the gas or use straight unleaded?
