Bah! Too kind! It was a fun morning. You take great care of your machine. I'm happy that we didn't have to drop the trans but that day will eventually come.

Glad it was a quick fix. So you just got a new belt from a local parts store?

It's a bit weird. The current accessory belt is nearly new but in addition to the cold start squeak, the tensioner swings like mad. I've never seen that IRL. People write here about it but I've never seen a video clip capture it. The new belt is flimsier than my original. More rubbery. We'll see.

When you "cocked" the tensioner to get the belt on, how much force did it take? As you know, it takes almost 1 full unit of ugga-dugga to move the tensioner far enough to get the belt on. Less than 1 unit may mean a failing tensioner. US vs CAN ugga dugga units may require different calibration.

I looked at that carefully. We compared ugga duggas with my tensioner. Equal and smoothly operating. Did not replace the belt. Just diagnosis. @Sur will get a belt from the dealer and test.
