I took my '02 out last night and got it pretty deep, nothing too serious, mainly water and not so much mud. It got it pretty deep, only stuck for a sec before pulling itself out, but then it stalled. Once it started, it idled fine, but when I put it in drive, the rpms shot up and the bike only rolled foward. Same thing in reverse. I would tap the breaks and I would hear a grinding, I almost wanted to throw up. I was pretty deep back in the woods, so I had to get it out of there. I flipped it up and let it drain, then dropped it back down and it seemed to be alright, it would get up to about 10 mph then the rpms would climb and the bike would jsut roll. I took my time with it going very slow, and it slowly got better. I got it out on the main trail and slowly got it up to about 40, then ran it steady at about 35 for about a mile. After a good 30 mins of riding, being very careful and a few times the belt felt like it slipped, i power washed it as best I could, and it seems to be running fine. I took it out in my 5 acre field and just road it around hoping to dry out what ever it was, now Im worried I could have made it worse. Should I take the tranny apart and clean it out, or is there something more complicated wrong with it. Im kind of worried, Ive only had it now for 2 months. Please let me know your advice.

 

I am not sure what is wrong but you should take you centrifical clutch assembly apart and look for something wrong. Since you said you cleaned it I don't know what is wrong. Mud was my first guess, just check it out and if worse comes to worse, take it to Yamaha, you do have a 6 month warranty,

Its seems to be running perfectly fine right now, but could I be making whatever it is worse by riding it?

 

you probly got the belt and clutch wet and now it has dryed out and is working ok again.

 

Sounds like to me you got the belt wet... Might want to consider a tranny snorkle if you are going to use the thing as a sub. [img]i/expressions/face-icon-small-smile.gif[/img]

 

speaking from experiance, i can tell ya to tear into it and clean out rthe clutch. unless you have filters on your intake and exhaust snorkle, you probibally have crap in there. i have yet to come across water so clean that if i swamped the belt nothing else got in there. take off the side cover, and clean and grease is all up. sand, mud, durt can reak havoc on the clutch!!!
if you have not done it before, email me. when i get back on i can tell ya how its done, and wwhat tools are needed.
good luck, i have done mine about 8 times now, lol.

 

what exactly does a slipping belt sound like? sometimes when i first get on the gas from a complete stop, it revs a little then it jerks into gear, is this a belt or a clutch problem?

 

Mich 660 is right.I had to take my buddies 660 clutch apart after a swamping.What happens is mud and dirt............even dust after a while gets into the primary clutch assy.You have to take if off and disassemble it.There are plastic rollers in there that need cleaned and lubed.Even in dusty conditions they get a build up on them.It's not a real bad job if you are mechanically inclined even a little.I had a Kodiak and it is the same way.

Electricshift it sounds like a clutch problem, for the time it takes I would clean an regrease the sheaves, mic the belt and inspect the clutch while you are there. If you haven't done this yet it is a good excuse to do so.

 

LlyodXmas, If you had enough water in your belt case it has entered your primary sheave. Once water is in your primary sheave it will not drain out by itself. The water will then mix with the Grizzly grease to make Grizzly funky grease that will not be good for protection/ lubrication. Cleaning the sheaves is an easy job if you have a manual and some tools/ general mechanical knowledge. You don't say but I assume that this is a used ATV and if that's the case it is well worth the time to inspect and mic the belt. While there clean and regrease the primary and secondary sheaves, remove crankcase covers two and three as there may be trapped water behind them. Better safe then sorry and it isn't expensive if you possess general mechanical skills. Reply back if you need any assistance.
