My son and I finished with the clutch kit . We followed the directions to the tee. (thank you whoever said that).There is a big difference in the ride. Thank you for all the suggestions and the encouragement. The bearings were right. I do have another question. My head gasket is leaking. The dealer said that is does not happen often. He told me that I could retorque the head. Does this make sence? And if it does, what is the torque?

Is this machine under warranty yet? If so, have them change the gasket outright. I would not settle for just retorquing the head.

Like Sanny said, if the machine is still under warranty I would be taking it back to the dealer for service! :thumbsup:

retorqueing is a option but like was mentioned if warrenty available take advantage of that, if not still might want to take off head to inspect, the gasket is leaking due to a couple of reasons or a combination:
head bolts loose
broken head gasket (or partial blown out)
warped head so not fitting right to gasket, case.

heads on a machine are torqued from the factory and if they start leaking i would definatly look into why it is not just try to re-tighten and hope for the best.

The machine is not under warrenty. Can the gasket be change at home? I might want to retorque and see what happens.The leak is not in one area. It seems to be along the front of the motor. I am not sure of the what to torque it at.

You can try retorquing the head, but personally I would remove the head, clean it and install a new one. Takes some time, but it's time well spent IMO. Then again, I'm kind of anal about stuff like that, so take my thoughts for what they are worth. :)

I went to the dealer and ask about what torque. I showed him were the leak is. He said it was not the head(sorry boys) .He told me it was the cap. It is the very top of the motor. I started to take out the screws , but put them back with the 8lb of torque he told me. He said I could take it off, clean it , put a light coat of gasket seal on it. All I did for know is retorqued it. Does this have anything to do with compression?

Are you talking about the head or the valve cover? If it's the head gasket it needs to be replaced, if its the valve cover it should be replaced or removed and replaced with silicone.

Ditto, but it is such a trivial amount of oil, I have not given it much thought. One "easy cure" (I think) would be to go to a heavier oil. As this seems to (only?) happen with the 0w synthetic stuff. I think a 10-40 dino oil might/could solve this problem.

This is all speculation...

I do use the 0 20 synthedic oil. I know that the bolts follow the head. Are the bolts in the middle need to come off too? There are 4 or 6 I can not remember. Would it be better mark the bolts, being they are different length?

Does this take away any compression or horsepower?

^^^

Before you tear the top of the engine off, I would try some 10-40 dino (Arctic Cat sells a version). 0-20 oil is pretty thin and could be getting by you seals.

Using a "heavier" oil will not cause you any noticeable loss in power or compression. If fact (according to my owner's manual), A/C recommends it.

This could be an easy solution to your problem. Good luck...

I take it that a dino is a synthetic? Can I also use 10-30 synthetic? What is dino oil? I should clean the cover after I put in different oil to make sure it isn't anything else. What can I use to clean off the oil on the cover?
