seems to be so far when it is first warming up if it was going down a hill without giving gas it will act like it is coming out of gear then if i touch the brakes it kicks back in. it did it a little bit so i greased my clutch. (thanks texmudder for your page). it still does so maybe my belt is wore, it looked good while i was in there. i have a 02 grizzly 660 with 3600 miles.it has been a great bike

Mine started doing this last week right after I got my clutch cleaned. However, it doesn't kick back into gear when I brake...only when I give some throttle

 

[grizzfan]

Anybody knows what could be causing this?

This sounds like either a belt or clutching issue... I know the clutches control the engine braking, but I don't know the Grizzly's clutch design well enough to speculate as to an exact cause.

Its a bad one way bearing in the wet clutch behind your primary pulley.

thanks kodiak 660. this helps a lot, i really like (need) that engine brake.

 

[kodiak660]

Your welcome jim.

If you use automotive oil with friction inhibitors, would that cause it. I guess i don't know much about the Griz clutch either.

 

[kodiak660]

starky it would just make the wet clutch slip....I always use Yamalube 20-40 so thats never an issue. For what little extra I pay for the Yamalube its well worth it to me and my dealer treats me really well so I have no problem supporting him by getting my oil and filters from him.
The one way bearing is about the same as on the shifter quads with the auto clutches.

i have always used the yamaha oil but not there filter. i am just going to change the 1 way bearing. it is a pain in the rear with out my engine brake. i hate using my brakes unless i am going to stop. i found a hole the other day that was way too deep for me. never been that deep. filled my clutch case and even had some in with my sparkplug . now i carry a disposeable camera. i know this goes somewhere else in the forum but i am already here .

I have a similar problem. It seems to only happen when the machine is first driven after it has just warmed up, then after I drive it a while, it doesn't do it anymore. You can hear the engine brake disengage and it free wheels until I tap the throttle. I just had a tune up and valve adjustment done and it started after that, but I can't imagine anything involved in that would have anything to do with the clutch involved in engine braking.

Ill second the wet clutch one way bearing. Mine always did the same thing since I got it, figured it was kind of normal. I was coming down a pretty bill hill hot and heavy one night letting the motor hold me back and all of a sudden the clutch was "locked up" stalled when I came to a stop. After I tore it apart I found the nut on the crank holding the wet clutch on actually backed off and got jammed into the drum. I had already ordered all new stuff but all I needed was the bearing, nut and drum. Now the problem is gone.
