Maurice, I think you are onto something... As a side note, I've noticed that when the bike was new, engaging 1st from neutral while standing still was smooth (you could only hear and feel a tick engaging)... Today it generally bangs into gear... I'm wondering if the clutch is in a bind and having a hard time engaging and disengaging from the flywheel? Would explain the engine stalling while slowing down... I can recall our Dodge Challenger had that problem which resulted in grinding gears when clutch was depressed going into 1st through 3rd... The eventual fix was adding tolerance between the rotating assembly and input shaft, fixed the grinding gears... Apparently the tolerances were too tight... Furthermore, the rear LSD (limited slip differential) was very clunky while driving at low speeds. Fix was adding a friction modifier to (the differential box) allowing the clutch packs to engage and disengage more smoothly (less chatttery)... Is it possible that as our oil heats up, coefficient of friction for the oil doesn’t play well with our clutch material? Chemists design the oil to become more viscous as its heated. Generally this is achieved by making the molecule longer as it heats up… This longer molecule is more resistant to movement (aka higher viscosity) because it doesn’t slide against other molecules like itself as easily... The trick is, keeping the rheologic behavior (flowability) consistent...Assuming that the clutch material is created with a specific coefficient of friction while in a bath of oil, perhaps the oil or friction material are incompatible at operating temperatures.. Maybe this only affects those of us that have a combination of oil or friction material that isn’t center of their respective specs.
