Friend of mine just bought a 97 MM 600 and top speed is very low in my opinion. I drove beside him in my truck and top speed was 90 km/h. Sled hadn’t been running for quite a few years so we pulled the carbs and cleaned them and it fired up fairly quickly. The belt looks new on it and the rollers on the primary clutch are shot so he’s got new ones on order. Just looking for opinions on what would cause the top speed to be this low (I’m assuming it should go faster than that😁) And one more thing, it has a 2 up seat on it so would something be different on this sled (setup for trails?) compared to a normal MM 600.
