Ok 3 days ago I bought my first snowmobile. It is a 1985 Yamaha 440 SS. Th previous owner just put in new pistons. He seemed very reliable. There is 4,100 miles on it and looks to have had a pretty easy life. I am just wondering about any thing I could do to it to keep it reliable and cut future maint./repair costs. Any oil injection maint.? What type of oil should I run? Brand, synth. or not? The rear suspension seems to be lazy and low almost has a memory, meening it does not rebound like I think it should. Are there adjustents or maint. with rear suspension? Any links to good aftermarket parts sorces would be great. Thanks for any information.
