Check compression yet?

 

Pretty easy to take them out and clean them. On my wife's 04 600ho, they were gummed in place.
As for knowing if they are working, there's a write up on modifying the cap to see when they open, but I'd say if you take them out, you'll know right away if they were working or not.

 

If you determine the engine is healthy, clutches are next stop. Take them apart, make sure everything moves smoothly.
I changed a few springs for a slightly higher engagement rpm and different backshifting.
Is the track and suspension in good shape.?
Gotta get the power to the snow.

 

Thanks for the responses Fellas.

No, I haven't checked compression yet. Thought about it and it runs good, just more or less wondering if it's supposed to have a noticeable powerband. Probably should though.

Thanks, I'll have to look into that write up, but will probably clean them up. Trying to avoid buying that sealing gasket if I disassemble it.

I adjusted the secondary after putting a new belt on. It seems to put it down well, it just won't hang with the kids Indy. It's also 12yrs newer.

Track is great with 96 studs. Suspension definitely needs adjustment. It's to soft for me as I'm 6'3" And 300lbs. The guy I bought it from was a much smaller man. It will need risers though, the hand guards hit my knees.

 

Welcome to DooTalk first of all
I was intimidated by them until I took them out for inspection & there's not much to em...I don't remember having to change gaskets, just be careful pulling them out

 

Thank you for the Welcome. I believe it's called "Driebond", it's a sealant of some sort. I guess if I don't actually pull the valve apart I'll be ok.

 

There's a gasket between the block and rave housing, be careful and that one can be reused. I usually do not take the bellows off, the rave can unscrew with it in place.
And as said, clutches should get a good cleaning and maybe new bushings.

 

With the track in the air you can look through the window of the rave valves and see if they move. I believe they should engage around 6300 rpm. Keep in mind the motor unloaded will engage them differently than when riding. You adjust them by the red cap. If you run out of adjustment stretch the springs. Max rpm should be around 8200

 

I'll look into the valves, thanks. As far as the clutches, I'll have to hit the ole YouTube. I don't have any experience with them.

 

I was a clutch newb too. Lots of info on making some clutch spring compression tools. Easy with parts from hardware stores or premise here on dootalk.
There is a slightly stiffer spring from skidoo that raises the rpm engagement a few hundred. Hits a bit harder at take off.
Numerous you tube videos. Really helps.

 

I'll have to see what I can do. Gotta try to keep up with the kid....I figured between those valves and the reeds it would've had a significant change in the powerband. But it pulls nicely as it is.

 

Here is part 1 of 4 from Dynamo Joe on full tear down and reassembly of primary and secondary. Should be 95% the same as yours.

How many miles on the sled again? Could maybe use some new springs in both the primary and secondary. Check the primary ramps for any ridging.

Does the belt look old? Couldn't hurt to get a new one, break it in, and see what she does then. At least it's a starting point for that. For myself, I don't mind replacing wear items even if they look new. I have a ground zero so to speak.

Thanks..I watched those, I'll have to look into purchasing some tools.

2800 miles

I just replaced the belt and adjusted the secondary.

 

Well your belt needs 40 or 50 miles of break in, wont pull good until some miles are on it.

2300 miles? Do you know if the engine was ever opened? In 03 skidoo had issues with rings on the 600. Delamination caused some compression loss. I think they had a recall on it??
Maybe yours was never updated.

 

Love the video!!! lol

Yea i'll have to put some miles on it and see how it is.

Thanks for the link, I should probably order some.

2800 miles and I have no idea. I doubt it actually. Guess i'll have to run a compression test. If I called the dealer, would they know if it has been updated? Are all the dealers tied in on a network or would I hae to find the actual dealer that did the work?

Thanks a lot fellas!!!

The dealer should be able to run the vin and see if the recall was done.

So long as a dealer did the work. If you check and there's no record of it, that isn't a guarantee that it was never done. But further inspection would be needed.
If you pull the raves, you can look in at the piston and rings. Same on other side by pulling reeds.

 

When I changed the reeds, I looked the piston over from what I could see they didn't look to bad.

 

"how can I tell if the RAVE valves are working?"

insert a switch to each RAVE and wire a pilot light for each
