shifting issues

[Harmony 44]

At a guess, I'd say that you are probably worrying about something that's just the nature of the beast!! Still, there are some things that could (might?) be an issue - I've never encountered one of these without already knowing it's there, so I really can't relate to the riding feel/symptoms from a 'not knowing' diagnosis point of view; but from what you describe & what I've felt when test riding a belt drive bike with this issue, I really think that it might just be worth your while to (carefully & tooth by tooth) check the teeth of the drive belt for damage or loss.

For what it's worth, that 'bump' in first at slow speeds &/or as you start to move off is one of the symptoms you get warned to watch out for on bikes running damaged but not broken belt drives; & the way you describe it certainly does sound like you might have some tooth damage or even possibly a couple or a few teeth missing! And if you do happen to have a couple of teeth missing from the drive belt, one of the symptoms to watch for there is the drive 'lurching' immediately after changing gears or as releasing the clutch.... could that be your 'clunk'? Also, if you're minus a couple/few teeth in one spot on the drive belt, backing off & then reapplying the power will generally tend to give you the feeling of 'a bit of slack' in the driveline as the drive belt skips over the gap in the teeth & then catches up with drive delivery - sound like a familiar feeling?? The noise, got nothing really on that; & considering that I'm definitely not saying this is a cut & dried answer to all your problems, but it does sound suspiciously like the things we are warned to watch for & what I've experienced when test riding bikes with a couple/few teeth missing from the drive belt.... :shocked:

Just sayin'

I too can't speak to Tim's specific issues other than the shift quality is much like mine. My issue was picked up at the dealer when they performed the first service and road tested it. I just thought it was normal because it was like that from day one, but the tech said it was "DEFINITELY NOT NORMAL", BRP said to replace the part per the DTC (P0810). Hopefully I'll know more this weekend.

Picked it up Friday afternoon and rode it 300 miles today, I would say it is normal now. It slips into gear very smoothly at 2700 rpm and a slight pause over 3000. Hard acceleration leads to abrupt shifts, but noting like it was before. As far as driveline backlash, yes it is noticeable now that I am paying attention, but only if I abruptly chop the throttle and then accelerate hard.
