I have a 2008 m109r. Recently, the aftermarket clutch cable broke. I replaced it with a new oem one. When accelerating, with rpm exceeding 4000, the rpm goes up but there is very little gain in speed. It feels like the clutch is slipping. I did notice the same issue with the old aftermarket clutch but not to this extent. Now, it is hard to ride the bike. Did anybody have the same issue? Thx in advance.
