I have a 2000 748 that is running great except ...
When riding at a constant speed, the bike starts "surging" almost like I'm giving the throttle a quick twist and then letting it go. This does not seem to happen when I'm accelerating; acceleration seems quite smooth.
I can feel the same (or at least similar) when I'm in gear and coasting to a stop (but still with enough rpms to not stall the bike). I do not feel this at all in neutral or when I pull the clutch. It *seems* to be tied to the engine/drive.
I first noticed it very slightly a couple of years ago, towards the end of last year it got a bit worse, and this year I'm growing rather concerned (and annoyed).
I have checked the chain against the manual and it seems to be the correct tightness/looseness. I don't see any physical wear on the sprockets.
Any help would be appreciated, thank you.
