My revs used to hang above idle before I cleaned my carbs. As for the "knock" when shutting down, the engine is spinning down and things are moving slower, inertia, spring forces, compression, etc. can cause a little backlash of parts. Mine makes a nice little noise when I hit the kill switch as it dies, not sure how to describe it, but engine shutdown noises don't need to be worried about. If it's knocking while running of course that's an issue to investigate, but otherwise ride on.

Pickup coil mod is good, I like it. I can usually grab a little bitty blip of throttle on hot starts that helps fire it up, with the coil mod it's even better and gives it a little extra oompf. I run 89 octane ethanol-free to keep the carbs clean and it runs well

Could be the throttle cables getting stretched when you turn the bars to the left, mine does that. I noticed yours slowed down when the bars went right.

I bought the bike in sept last year so this summer has been my first experience with this bike with real summer heat, I’m sure things are expanding even more. Thankfully no knock while riding, and I couldn’t reproduce it but I’m going to try again. The knock sounded similar to when you pull away and don’t quite give it enough gas right before it stalls, that’s the best way I can describe it. It caught me by surprise. After the stator I don’t want to deal with any more major repairs, something else major goes I’ll be looking for bike number two! Hopefully don’t need to go that route anytime soon though.

Definitely interested in doing the pickup mod when the weather cools, just don’t feel like roasting outside, if you watched the short vid I posted that’s essentially my work space lol. No shade till late in the day this time of year.

Will be checking this as well, KM threw that out there earlier. Feels like I’m chasing a few separate small issues all at once,
