550 K1 : up-shifting issues (mostly low RPMs)
Nurse Julie:
Haha, yes Erny, you will not understand me because I am remembering another bike where the lever touched the casing 🙄🙄🙄 Are you sure there is not a dot there, it may be so small an not even look like a dot but it must be there somewhere. I cannot increase size if your photos to see properly though.
K2-K6:
Your current picture shows the gear lever one or two splines further up than the original position, that will definitely make a difference.
Erny:
Just to be sure, this is how it is now, so you think I should move it even lower?
K2-K6:
I thought the pictures where the other way round.
As long as you set it so that it's as close to your foot as possible but without it being constantly moved, then that's the best you can get it.
It should be able to rest so that you don't drive it with any constant pressure on the lever, but you need the most travel you can get with your foot to complete the gearchange action.
Erny:
After loooong time (yes, more than 3 years!) I'd like to update this thread.
Up-shifting issues is still there, getting a bit worse now.
Meanwhile I was testing and testing.. my findings:
- only pb is in up-shifting (down-shifting seems to be normal to me, w/o any fail)
- issue is present ONLY when using clutch
- while up-shifting w/o clutch (short trottle release and quick lever moving up), it works perfect, smooth, even in lower RPMs
- when starting up from zero (for example when standing on traffic lights), while fluently releasing clutch as normal, bike starts to pull, but when clutch becomes fully engaged bike "kicks" (not sure how to describe it better, as English is not my native language...). This was present since I got the bike but I attributed it to hardened rubbers in rear wheel sproket carrier. Now having those rubbers new, I know it is something in engine/clutch.
Considering all above, I suspect it is clutch responsible for those issues, so I need to check it (winter project)
I tried to search quickly forum, did not find similar problem described - do you have some idea what is wrong?
Or, at least, recommend what I should be prepared prior opening engine (clutch cover)? I already have new gasket ready...
Thanks
