any have any probs with the 4WD and diff lock on the grizz 660? mine would engage 4WD then the diff lock but then the diff lock would not disengage until i took it out of 4WD totally even then it made a funny noise not like the usual noise u here. Also when i lock up the rear break over 10 mph there is a loud clanking sound, front brake doesnt do it though and all the pads are fine only 400 miles. Am so fed up with this quad thiese are just the next problems ive had, broken axel(complete snap in the hub) dealer said it was because i have 26" titan 589's. also belt slips constantly in 6"s of water. and had clutch plates "explode due to cold water hitting hot clutch" so i was told by the dealer. had to buy extended warranty because i'm just waiting for something else to happen, i'm afraid of going on long trips because odds are i'll end up being toed back. JUST DONT KNOW WHAT TO DO.

 

grizzkiller, the clanking noise you hear when you lock up your rear brake is normal.....my 03 grizzly does it too, it's just driveline chatter......annoying but perfectly normal.....i've heard of others having the same thing happen too, so don't worry about it. As far as the 4wd problem, I don't know. Sometimes my diff lock doesn't dissengage until I go forward or backwards a little after I've pushed the button to dissengage it, same with the normal 4wd button. Without seeing it happen on yours it's a little difficult to speculate whether it's normal or not.....I'd take it to the dealer just to be safe. Concerning your clutch belt getting wet and slipping in 6" of water, check the drain plug at the bottom of the tranny housing to make sure it's sealing properly. 6" of water should not be enough to get anything in there wet. I've had my grizz buried in water up to the seat and when I pulled the drain plug on the tranny housing not one drop of water came out. Also check the gasket that seals the tranny housing cover. May also be a good idea to check the play in the belt. If the belt is too loose it will slip. Trust me when I tell you that you made the right decision when you bought your grizz. I had a prairie 650 for a week before I bought my grizz and it had more problems than I could count.......biggest piece of junk I've ever bought. Yamaha is simply a better built machine. Hope this helps.

 

with mine i have to slow down to about 5 mph and the dif lock goes off. i have not had any problems with mine.

 

Do all grizzs have alot of problems?i.e. Driveline, belt slipage, overheating, gasboil/vaporlock.... I'm considering either a Grizz or a Prarie, I would prefer the Grizz but, the last thing I want is a new bike with a bunch of BS problems.

 

Sounds like you need to find a new dealer with a better service department. The only time the four-wheel drive and lock stays "in", is if there is a load difference between the front and rear diffs. Put a tape measure around the circumference of your tires and make sure they are the same. I've noticed this before I had a flat tire and it was going low on air pressure. The belt cover is sealed, and air vent is up around the seat height before water will go in, and if water enters the belt cover, pull the plug to drain, and move on. No offense, but it does sound like your name fits! [img]i/expressions/face-icon-small-smile.gif[/img] I can trace almost all mechanical failures of my toys to abuse. I once have the cases explode on a 600 Grizz, that a buddy and I were jumping, with 27" mudders on. Took the teeth right off the output of the engine. That was ugly.

 

btw, the brake noise is normal, it's because the brake is located on the driveshaft, to keep it out of the mud, and that's a good thing. You'll only notice a noise under hard braking, and after a while, you won't think twice about it.

 

no offense taken, its not my grizz, I own a rubicon, its my friends i just wrote like it was mine because he wanted me to ask the questions for him. not that i think it is junk, all machines have their probs i was just curious about all of these problems because i own a rubicon and had no problems other than a bad spring in the choke. and you are right alot of things happen to abuse and my friend does ride the grizz pretty hard. I understand the brake and diff lock , all normal no problem, but the constant water in the belt housing is bad, had the belt housing changed once checked the seal, no leaks, still gets water inside. Question! is the belt intake right under the front fender? and belt exhaust opposite side of muffler under the fender? If i am correct than i must say BAD DESIGN!! my opinion (which is worth nothing) is that it has all the good qualties of a great utility quad and more, BUT poorly designed or executed. then again it maybe a lemon, but thank all of you for your help!

 

That black thing that you might call the hood under the front rack, thats where the transmission vent is. If you put that underwater, you are going to get water in there. I haven't really had any problems at all out of my grizzly in almost 2 years now. I'm not defending them either though, cause seems like some here have had a lot. Some because of yamaha, and others cause they just could tear up an anvil with a rubber mallet in a sandbox, but thats beside the point.

How are your brakes on you Rubi? My buddy has a Rubi with absolutely crap for brakes, but we just put the highlifter wilwood disc system on the front of it and its unfreakin believable what a difference it makes. Highlifter needs to come up with a solution for the rears now. Also found that the HMF exhaust will really wake up a Rubicon too. Worth every dollar.

 

i have 1339 miles on the rubicon and the brakes feel like the day i got , they work good , i have had no problems with them at all, i ride alot of deep mud and water as well. actually when it was real cold and deep snow my brother and his friend have praire 650's and they had a little problem with the front discs not grabbing too well. i will change my drum pads soon just for regular maintenance but yeah they work great, the engine breaking is so good though you rarely need them. i thought about a pipe for the rubi but i'm not one to rejet. dont think it is too good for the machines reliability. put the K&N filter, ramsey 2500 remote winch, and a nice set of gators and i'm good to go!!!!!

 

His Rubi is night and day with the jet kit, filter and HMF pipe. Absolutely smokes a stock Rubicon. Also raced my cousin's 454 AC and ran off and left him (plus he had a passenger with him while he did it). Of course its a lot louder now too, and I guess some people are bothered by that. He rides a lot of mud and cleans out his drums a lot, but it just was a losing battle. Those fronts were shot, and the rear needs a new cable. The Wilwoods didn't impress me as much as I thought at first, but after about 20 miles they were awesome. I guess the pads burnished or something finally.
