The winter has came, so time to get fingers dirty. I've started getting closer to the timing belt of my ST (I acquired it a month ago with 150.000 km), rode for almost 1.000 km and got into garage. Started opening it up, and got to the the timing belt side cover today.
Question to those who touched/changed the belt yourself - is there any slack, which is assumed normal? You can see in the video - it moves really easily, with no force applied. I was also able to stick a finger and roll the top idle-roll (free-roll?) without issues, it slipped through the belt with ease (actually it had a dark spot on the bottom - i doubt the belt is able to spin it with the tension it has). What I saw on the timing belt videos - it should get really tense when you put a new one on, and release the tensioner for the spring to do its job.
I am almost sure belt was not changed through 150.000 km, so now it is time to open it up and do the maintenance anyways.
There is also a hollow knock when on low RPM (idle and a little bit over it), not sure yet whether it is coming from the engine block, or one of the spinning parts in the timing belt area. Anyways, I'll get to work, just want to understand what parts I need to order (except the belt of course).
A bonus question, if the belt jumps a tooth, would the engine still be able to work? Apologies if question sounds stupid, but I was taught there are no stupid questions (this especially applies to the off-season)
