There used to be a good explanation in the Tech section of this web site. I assume it will be back up and running, when Corey launches the new site.
So you only have 14 day, 8 hours, 42 min and 30 sec to wait.(no 29sec, 28sec, 27sec, 26sec) well you get the idea.
Its really not hard to do. Infact I did mine with no instructions.
In simple terms,
1 - pull the plastic cap off
2 - undue two allen screws
3 - watch spring pop out, and chase it across the garage floor (JK - but watch for the spring)
4 - pull off spring or zip tie from rubber boot
5 - pull valve out of cylinder (may be hard, it helps to soften up the carbon with some carb cleaner)
6 - once apart, clean everything up with carb cleaner and a scotch brite pad
7 - reassemble everything (make sure valve is put back in the right way "this side up")
From memory thats basically it. You may need new gaskets depending on the shape of them. Once clean, they should move freely in and out of the cylinder. A rag with cleaner and srewdriver may be necessary to get in the tight areas.
I'm sure I'm forgeting something, its been a while since I have done them. But I'm sure that will be enought to get you throught it.
Yeah, what he said. Also make sure the small hole is not
covered by the gasket. And double check to make sure that
the valve is facing the correct direction. Screw red cap in
all the way if in lower elevations.
Ya, FishHog pretty much said it except why would you pull the spring and rubber boot off? None of that has to come off unless it's an old rave set up. A sharp putty knife on the gaskets will keep them from breaking but be gentle.
On the RAVE valve cleaning instructions mentioned above and on the web site posted... both indicate that the vlave has "TOP" stamped on it. This is not true on my 96 for whatever reason. So, first time I had them out, I took it to a local dealer to confirm the installation (in case the prior owner had them in backwards)... what they told me didnt seem right... so went to another dealer.. they told me the opposite. Not the first time this dealer messed up...now they are no longer a Bombardier dealer. (they keep selling Honda's though.. hmmm).
I run a drill bit by hand down the hole to make sure the passage way is open.
I've made myself a small slide hammer to pull the valve out in case it is stuck. Since I went to the Amsoil, this hasn't been a problem. I'll post a picture of it when I get a chance. The thread is metric.
Yes, Yamalube in a doo! I love my Skidoo's, but, if I have one bad thing to say about Skidoo it's their OIL! I think they recycle it from diesel trucks to tell ya the truth.
An average season for most is under 2000 miles. Mine is a little more and come spring I pull the raves. They really dont need cleaning, but I do it anyway just to be tip top for next season.
