I know this is car talk. But I know many of you guys, and girls, work on motorcycles and snowmobiles. For those of you who do, if you have a good idea let me know.
I have a Ski Doo Mach 1 early 90’s. Just got it this season. It starts ok. Runs great once started. After it warms up, perhaps 3 miles of running about 50 - 60 mph, it starts to lose much power. Almost makes you feel like it is going to die before you get back home. Actually the other day it did die after it was idling and it would not start until I let it sit for 5 minutes.
I am going to try putting new plugs in and getting a can of SeaFoam, half a can. I was told the clutch was changed very recently. I am not sure if clutches that are bad have troubles when warm and not when cold. And it does not feel like a clutch problem. And of course like I said, one time it died at a idle and did not want to start. This would have nothing to do with the clutch. Seems to be in the motor so I am thinking either electrical or fuel. It will just start to dog down and the sound is greatly changed. Sounds like a booooooo noise if that makes any sense. When it is going good it has a higher pitch when the problem starts it is a lower pitch. Anyone have a Ski Doo and have this same problem?
