Hi, I had a question regarding my old mans sled which is a 1993 trail deluxe 440cc. I know how to do this adjustment on my Ski-doo but I could not see a logical means to adjust the belt on the 93 trail. The problem is that at idle it will squeal a little, but as soon as he revs it (i.e. to take off) it starts to squeal quite badly. Once, he's going maybe 5mph (guessing) it goes away. My thought was that the belt is too tight but I couldnt see where too adjust this. Does anyone know how to render this problem? Be it belt to tight, clutch problem, etc. Any help is greatly appreciated. Thanks.
