When I first bought my new Grizz it would not pull the front wheels off the ground either in High range, but now with 53 miles on it it is a different story. I weigh 280lbs and it will lift the tires off the ground now, that is from a dead stop and hitting the gas. The more miles I get on it the more impressed I get. In 4 wheel drive the torque is very impressive, in high or low range. I grant you my 660 Grizz will turn over the big mud tires in the mud, with no problem.
Very impressive power. These guys that say their utility bikes will smoke this bike might have to eat their words one day. I am talking stock bike to stock bike.

 

thenewfiebullet,
I am only using my short little test ride on both the new Grizz and the new twin Kawi as a guide,and from what I felt on my test ride,I beleived I would certainly SMOKE either of these quads.

Now,after I have read these Forum posts further,I see that the Grizz is indeed a PIG off the line when brand new and not broken in,however,after it gets a few miles on it,it really starts to show its power.I have no reason to disbeleive you guys,and im hoping all this ''break in'' stuff is true,because I am SERIOUSLY thinking about buying the new Grizz myself.I liked EVERYTHING about it on my test ride EXCEPT for the power.I am going to test ride a new Grizz that is allready broken in,and if it has indeed gained in power after this,I'll allmost certainly buy one.

I am keeping my eye on the new big bore Sportsman for 2002 also.Rumors have this quad at 700cc,however,it also is rumored that this PIG weighs 740lbs.If so,I will CERTAINLY buy the new,lighter Grizz.

Thanks to all for the great posts,

Bill

 

Hollywood,
My 2002 Grizzly has 23 hours on it now and it will wheelie without any assistance above 15 mph on a moments notice (in either 2 or 4 wheel drive). I believe that Yamaha intentionally built in the flat spot down low so one could drive it in the slow, technical stuff without getting killed. As far as automatic slippage, I've driven dirt bikes all my life and this thing has NO slippage in high gear. I believe that the new Griz in low range would have the power to turn over any ATV tire currently made by any any manufacturer in any mudhole any sane person might enter. I've also ridden the Kawi 650 for a half hour or so off road and was impressed with the sound and smoothness, but I'd buy the Griz again without ever looking at the Kawi again.

 

I got my Grizzly last week and rode maybe 4-5 hours so my time on it is limited but I can honestly say this...when you nail the gas you better hang on because after the so-called "flat spot" this thing comes on strong.

 

The new Griz obviously has the power. I'm considering swapping bikes but I don't like the comments about it sputtering and coughing in mud and water. My Kodiak did this at first till I put some Dialectric grease on the spark plug. Has anyone encountered this and is it a simple fix or a design flaw??

 

As a long time snowmobile clutch tuner I can tell you getting that flat spot out is not a problem.
First thing to check is belt deflection, the easiest way to do this is to take the belt gaurd off and see if you can spin the belt thru the clutches, if you can remove washers in the secondary untill the belt is as tight as possible. make sure the machine will not move when idling, make sure to give the belt time to thourally warm up, drive the machine around for awhile. Other things to do such as increasing primary spiring pressure, engagement notches, ect., will solve the problem. Remember a drag bike and a all around bike need differant clutch set ups.

Yo Hollywood heres the deal apparently when the pinion bearing was pressed into the case the outer portion of the bearing cracked and the ball bearings started to fall out. Yamaha overnighted an entire new differential to the dealer and they are going to install it tommorow. No charge, cant beat that. It is the right thing to do connsidering the quad has only 10 hours on it. No one questioned my operation of the vehicle or weather it was abussed. They damn sure would not have wanted too neither. Or I would have been a Bear with a much soarer *** than I allready was. But my dealer is handeling things very much to my satisfaction. I still love my new Grizzly despite this glitch. I have never ridden a utility quad that handels as nice as this thing does. The i.r.s. setup is similar to the system Jaguar uses on there cars. Unlike the setup Suzuki uses on there quads the tires stay flat on the ground they do not fold under when cornering hard.

 

HEY WOODWARRIOR! Whats your problem dude? Man i was just joking around making a conversation and here you go getting all smart with me for no reason now that was uncalled for.Im sure everyone else feels the same way.Now I see your point,but that has nothing to do with atving i think u should apologize.Im not trying to dis firestone or put the blame on them or whatever you presumed but u need to take a chill pill man. jus sayin , not tryin to start anything, jus wanted to clear things up. take it easy dude, cya

 

Hey Hambone,
Thanks for responding, and I do agree, them mailing you out a new diff was pretty cool, and very professional in my opinion. Thanks to everyone else who has responded also. From what you guys say, it really is powerful after its broke in, I'll remember this when I go for my test drive on it tomorrow. I'll let everyone know what I think.

 

Hambone you should post an update in the thread you started. People that read it will wonder what happend.
