1990 skidoo safari clutch problems??
Hey guys, I recently came across a 90 safari 470 liquid cooled and I need some advice (besides jumping off it just before that hole in the ice, lol). Before you give me heck, I read the how to clutch cleaning article and thoroughly cleaned with brake cleaner and used some scotch brite to clean off oxidation. I cleaned and blew out both clutches (I brake cleaned the snot out of the primary several times but not much came out). I noticed some rubber stuck to the primary about halfway up the sheave. Cleaned that off and replaced the belt. With the sled on a jackstand I open the throttle and watch the clutch engagement which it does fine but the belt only comes about halfway up the drive clutch while the driven seems to operate just fine. Also when I drive it, it takes off like mad but just isnt shifting up. I have checked for broken motor mounts (had that happen before) motor runs great, 150psi both sides.
So my questions are: Are there any telltale signs of internal clutch failure such as noise or anything?
If the clutch as to come off, is there a safe way to do it without a special tool?
I noticed while revving the engine up while on the stand that rpms topped out around 6500. Is that normal for this engine?
I can't seem to find much info on the single carb 462 but its gotta be around 65-70hp?? I feel this sled should be good for 130-140km/h on hardpack??
I know I'm asking alot of questions here, any help you can give me is greatly appreciated.
