Weird thing happened to my Raptor last Saturday.
We were dune'n along and found a sweet jump.....kind of a step up dune. Anyway I came up short one time cased it and got kinda stuck.
I was clutch'n the crap out of it to rock my loose. All of the sudden my clutch just kinda gave out. The lever got real spongy and it wouldn't start in gear with the clutch pulled in.
I checked my cables and all that everything was good. Sat around for about ten minutes to let things cool down and after that everything was fine....clutch worked good as new!
Anybody else experience this or know what caused it?

Thanks Shane

As you abuse your clutch, the heat causes fading. That is part of the purpose behind all the fast bike racers havin an on the fly adjuster by their lever. Stay on top of your oil changes, and it should be fine...and stop abusin that poor Raptor like that! Haz

Thanks for your reply.
I understand fading, wear and tear and all that stuff. But what gets me is it went from a good working clutch to a non working clutch and back to working again with no adjustments (just a 10 minute cool down).
I've been "abusing" clutches for 20 years and have never seen this happen.

Are you using the correct oil in your crank?

It has to be the non friction modified Yamalube, 20w 40w.

If you use regular automotive oil, or any of the crackpot no name oils, the clutch will go south like you describe.

If it doesn't say "Non Friction Modified" on the container, don't use it. No matter what the person selling it says.

Only thing I can think of.

My '02 has spent the past 2 seasons running hard at Dumonts wall and Big Moe, and no signs of any problems at all.

Thanks for the input!

The oil that is in there is from the factory. So I'm asuming it is the proper kind.
I'm taking it in for service this Tuesday. I'll ask the tech there and see what he says.
It's an 03' on it's second trip to the dunes. I gave it a good break in before the dune trips.....I think everything will be fine. Just wondering if anybody else had seen this.
Thanks again
