2002 Yamaha Grizzly 660 lock up and stall

Recommended Posts

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.

      Unfortunately I didn't notice some of the rust hitting the undercarriage of my 2004 Yamaha Grizzly 660, but saw it the other day when I was doing some maintenance, oil change, air filter, spark plug, etc. The left side footrest broke and that's causing the plastic to hit the front wheel. It broke right at the welds from too much rust. Looks to me like what I need is (looked this up on yamahapartshouse.com):
      YAMAHA FOOTREST BOARD 5KM-27481-10 Left side (broken)
      YAMAHA FOOTREST BOARD 5KM-27488-10-00 Right side (rusted and will probably break eventually)

       
      Does anyone have a less expensive source? I did see on ebay a couple of listings but it still comes out to @ $50 each,

      Well I will be Off the Trails for awhile...who will be riding ??
      I said awhile ago that we would be done for awhile,and we made it back out,but now I know we are off for at least two weekends,Wife is on Call.
      and I might send mine out for some due repairs,that I do not want to do because of the timing,and that I have not done them before.
      I need new brakes,front and rear!
      and A Chain and Gears.
      Deer Season is Nov.15th thru Nov.29th so no riding during that.
      And we need to clean the Garages to get the daily drivers out of the snow,and cold weather.
      So I hope that others step up and get in some riding while we are down.

      So here's the deal people, I have an old Avenger 350 4X4 Shaft Driven ATV. They only made them in the early 80's their thought of as the first four wheelers from around back when Suzuki made one in 1982. I believe the engine on it is a Kohler as I watched this video https://www.bing.com/videos/search?q=avenger+400+atv&view=detail&mid=1E10E939019CA07770031E10E939019CA0777003&FORM=VIRE but mine is a 350. That's if its original, and it all looks original. I am wondering where I can get parts for this engine, or really what engine is it. I have no way to find the year, unless you guys know where a serial number might be. Every sticker is worn off. IF anyone has any information at all on these old wheelers it would be greatly appreciated. I specifically need the gaskets for the carb, and don't tell me I could build them please I want to restore it as perfectly as I can. I can take pictures of the wheeler/carb if it'll help. Let me know.

      Hi guys I'm in the market for a new ATV.  I narrowed my choices down to King quad 750 Grizzly 700 and Rubicon 520,  I own a 2006 500 Rubicon right now and I like the reliability and power for plowing.  However it is not a capable ATV.  When quading with other guys it falls short with ride quality and ground clearance.   I also have a 500 King Quad 2015 which I like and will keep it for my wife.  It is very strong and reliable also.  However my plan is to sell my Honda Rubicon and replace it with a 2020 of one of the these mentioned above.  Can anyone give me their take on one or all of these machines and why you picked what you picked?

      The small waterline insert for the hose that goes from the water pump cover to the thermostat housing has corroded off. I only need the insert on top and behind the thermostat housing that the hose goes over and can't find just the insert. It looks like it may be pressed in. I've have been told the entire motor housing needs to be replaced. The pic with the red line indicates where the hose and insert would be and the insert looks like the pic of the water pump  Any ideas would be really appreciated.
