By reading the bulletins posted it appears that many of you guys are very experienced with snowmobile clutches. Last season, before riding season went into full swing, I took my clutch off, disassembled it and cleaned it. But to tell you the truth, I really didn't know what I was doing. Also it wasn't very dirty, because the previous owner took really good care of the machine. After cleaning it, I put everything back together, and didn't really think about it much after that.
This year (400 miles later) I'd like to take it apart and clean it again. I'd like to know the procedure. Which areas should I really focus on? What should I inspect? Any special cleaning solutions that work really good?
Also, I'd like to bump the engagement RPM up from 4000 to something closer to 5000 for a better "off the line jump". Would a change to a stiffer spring accomplish this or is there more to it?
I'd appreciate any help.
