Help with Grizzly 660

Recommended Posts

Hey Guys

I've got an 05 Grizzly 660 it's got a jet kit and k&n air filter installed it also had a hmf exhaust but i took it out cause it was just to loud it runs great untill it's under heavy load

when it's under heavy load it sputters like the limiter kicks in

if I hammer on all the brakes and then push on the throttle till it's full out then it starts to sputter going up hill and in mud

it does it in HI and in LOW gear

what could be the issue

thanks in advance for your help

It was already installed with the HMF and yes it ran awesome so maybe it is getting to much fuel there is a dj160 main jet and needle is set to middle clip

      Hey I have a 97 bayou 300 2x4 (klf300b) that i bought for 1000 last June and sunk another 1000 into it already.  When i went to look at it, the seller had warmed it up before hand (he was riding it when I got there).  it ran good so i bought it and took it home that evening... next morning it wouldn't hardly start.  I discovered the carb was clogged, there was chunks of rust in the fuel valve, the choke lever was missing and other things.  I have since cleaned the carb and replaced the fuel valve and gas lines and cleaned out the gas tank and cap.  
      Enough background on it, the problem is this:  It floods if i push it past half throttle in 4th and 5th gear even going downhill and shifting correctly.  It also has to idle and warm up when you first start it which is really annoying now that its cold...  It also smokes blue smoke for about 15 seconds when started cold-  does not smoke at all once warm but the exhaust still smells like burnt metal.  A friend told me that it didn't have enough compression.  I also found out that the valves are a common cause for low compression on Kawasakis..  I have never adjusted valves before-  the most I've ever got into a engine was a head gasket on a riding mower so I'm new to this.  My goal is to get this bike running and starting cold like a top-  should i tear down and rebuild the top end?  What should i try first?  I tore the carb apart and rebuilt it and fiddled with the air screw and nothing changed.  I also ordered a compression test kit that should be coming in soon.

      Ive also considered just selling it for like $500 and taking the hit-  Id rather not sink too much more into this machine..  lol

      got 7 atvs off CL recently for a good price.  one of which is a yamaha warrior.  anyone know where the vin is printed on this bike?  Haha good place to start as I do not know year or size yet.  The former owner says needs exhaust ans and clutch work.  he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears.  things I see:  clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box.  I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first.  also, battery (looks brand new, what a shame) is dead, 0 volts.  Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last).  any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
      the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like.  lol I'm spoiled on my automatic polaris

      Hey guys, figure you guys would have some helpful direction or answers.
      So, 05 Sportsman 700 carb, new carb, fuel pump, new plugs, new air filter, new everything I can think of that is usually the running issues. Starts up fine, seems to run fine, but if under load, two people, or even one person, up a hill, or pulling a drag chain for the driveway, it starts to cut out and sputters and loses all power, until I back off on the throttle and just barely try to let itself catch itself and then I can take off again.
      I am going crazy trying to figure this thing out. Other than that, the quad runs great. Parents bought bran new, just used around the property, 5000 miles on it. Any ideas???

      I have a 2018 Sportsman 450 HO and from time-to-time I hear what sounds like exhaust noise through the cowl near the gas tank.  Could it be an exhaust leak or am I hearing something vibrating?

      This is more of an informational fix I wanted to share..
      My Grizzly has been getting harder and harder to shift this winter and today was completely stuck and I needed to plow the few inches that came down this morning. First thought...oh no, tranny...but it’s winter and maybe it’s iced up. I pulled off the plastic to see what was going on and indeed I did find the drain tube iced up. 
      I took the blow dryer out and de-iced it. Quick fix, I never really thought about the shifter drain tube icing up before, shifts like new!

      Can anyone give me guidance on my issue. I have a 02 Grizzly 660 and replaced the wet clutch, primary shaft, one way bearing.  Today I was riding since I tested and was driving about 20-25 mph and all of a sudden the tires locked up, heard a screeching sound, and engine died.  Didn’t have a clue what was going on, decided to try and restart, engine turned over normal but engine hesitated slightly, started and had to assist with the throttle.  It seemed to do this for a minute then seemed to straighten out.  Got home, pull clutch cover and test drove to witness clutch operation and everything looks and sounds perfect.  Could not duplicate.  Please help.
