OK guys, I can't resist this one.  Buddy of mine finally upgraded from two 1987 Ski-Doo Stratos' for him and his wife.  He ended up getting a 98 ZL500 for his wife, nice sled, and a 99 ZR 600 carb for himself.... He said the sled is stock except for the clutch.  The one good thing is the dealer that I got my sled from is where the previous owner bought it and I know the kind of work they do (Good work).  However, I was sort of concerned when he said the clutch engages fairly low in the RPM's (2500-2750).  Is this setup OK or is there something that could be broken to have the clutch engage so low? I'm pretty sure stock 600's engage around 4 or so, so thats why I'm a little concerned.  I would hate to see him have any problems with his first Ditch Pickle.

Thanks

Steve

I have a 98 zr 600 carb with the opposite problem.  Clutch engages at 5800 rpm at tops at 83-8500.  I have been told to check the specs on the springs and weights.  Mine has a yellow/white primary, 49.5 g weights and a yellow secondary.  Not sure about helix angle or hole location of secondary.  Hoping someone out there has advice that can help us both.  I don't mind it, but it eats the gas up and bogs in the straight-aways.  A little ski lift out of the hole is cool though.  Haven't had a chance to race anyone yet.  We finally got some snow here in IL, Chain-o-lakes area!!    Good luck.

Well, your spring is stock, accordng to the microfiche online.... have you had any work done to the clutch at all?

If not, I would definitely bring it to someone for service...

sometimes when your engagemant is real low like that you have a broken primary spring .  and since you are going into it you may as well check the washers on the cam wieghts  (you never said how many miles ) that would be a good place to start

I would take the clutch apart and check it out.  More than likely you will have to rebuild it.  You will need new weights, pivot bolts, and washers.

rookee,

Thanks for the advice. I took a good look at the spring and sure enough it was broken. Luckly a buddy of mine knows an ex-arctic cat master mechanic and he changed the spring and check the clutch over for me. Thanks again! She is purring now. Cheap fix, well sort of! Now I owe my buddy a new hood and windshield. Had to take it out for a test ride on the icy golf course behind his house. Then we switched sleds, I'm following him, he locks the brakes up trying to slow down to cross a small bridge over a ditch, I can't stop on the ice, go to make a turn to avoid the ditch, sled slides out from under me, studs and carbides catch, then the sled rolls over, and over, and over, I go flying, boot comes off in the track, sled land upside down. Ouch! For the sled I mean, I'm just bruised up but the sled has about $800 worth of damage. There goes my tax return. Time to slow down, at least when it's icy! Thanks again!

Anyone know where to find reasonably priced cat hoods for a 1999 ZL 500?
