I was running the engine on my Uforce 800 and the exhaust started running deeper in sound than normal. When I looked at the muffler it was cherry red. As I pulled it into the garage I noticed low power as well. What could be the issue.

I have a 2015 UForce 800 and I replaced the front drive shaft because the collar broke on it. Now it won't come out of 4x4 and the drive shaft is hitting the sway bar. Do I have a front differential issue? I am looking for ideas please.

I've seen a lot of good things on this forum and it seems very friendly not cut throat like other forums I see. It convinced me CF Moto was the way to go, I guess you could say this forum finalized my decision. I just bought a 2015 Uforce 800 left over, the previous CF Moto dealer went out of business in Anchorage Alaska and another dealer picked up the product line in Fairbanks Alaska. Looking forward to good times in comfort.
