clutch adjustment?

I been having trouble with my clutch. Is the only clutch adjustment on the clutch lever? When I take off from start the cluch engages like the last 1/4 of the way every so often I will stall it. I think I need a new clutch.

For starters you should check your clutch fluid's quality. Are they fresh?
Once the clutch's plates are worn out the clutch master cylinder adds the extra required fluid from the bottle when you let the lever go.
If your lever is in 2nd or 3rd click's position and you still engage on the last quarter of it's way, then you should take your master and slave cylinders for seals renewal.
I would definitely start from those.

How many miles are on it? Has anything ever been opened up?




I'm always right.

When you say take-off meaning as in race/drag start or normal riding, as the gearing and set-up of this bike is not for quick starts.
In reverse logic of braking systems when the hydraulics become less effective the clutch engages and does not disengage easily, which to me describes your condition as a worn set of plates or inappropriate lubrication or both.

Race bikes only slam-drop the clutch with this gearing once in the race. In street conditions if you do this too often you burn-up your clutch and cause severe stress on the transmission (from primary gear to cush-drive)

To answer your first question...there is no adjustment as the clutch is hydraulically actuated, it is the actuation on cable clutches that is adjusted the hydraulic ones are self adjusting.

You may need a new clutch, the proper way to check is to disassemble, measure and inspect.

Download the manual or take it to a shop if you are not qualified to do your own work...

These clutches do engage a bit later compared to other bikes as well, takes a bit getting used too. is it new to you?

I'm new to the rc51 my bike is a 2000 with little over 15k on it not sure how many owners but i know at least 3 including me. I'm sure all the fluids are old i know the bike sat for a few years before i got it. When i mean take off from start i mean from any stop. I don't race this bike it is all normal street riding.

honestly i'd say change out the fluid and see if that helps a bit. But like i said, the clutch engagement is a bit late compared to other bikes, and can be tricky to new riders to this bike.
