I bought a new to me bike last week – a 2006 Sportsman 800 X2. It has 26-inch tires on the front and back. Went for a nice trip in Southern Alberta last weekend and everything worked fine (light snow, mud / rocks). When we got home, I washed it down. Took a ton of mud and rock off the bike. Weird thing is – when I started my bike to put it away, it went into any gear, but didn’t move very fast at all (like the clutch was slipping). I shut it off and let it sit for a minute and started it again. It did the same thing until I revved it up to 5k, then it sped up. Now it seems to work normally again. Thoughts?
