Slipper clutch dragging

[jock mcsporran]

Was moving one of the bikes the other day and popped it into 1st to walk it up the trailer ramp but with clutch pulled in it started walking up itself before stalling once the back wheel hit the ramp.
I’m not up on how slipper clutches work but it doesn’t seem normal and not noticed it before. Cable doesn’t have any freeplay although there’s not much adjustment left on it so will probably change it anyway. Anything else to look for or is it a case of open up the clutch and take a look at the pressure/friction plates?
CBR600RR in case it makes a difference. Can’t remember what slipper clutch is in it, previous owner fitted it.

Nothing to do with slipper clutch. The slipper bit only works when you're off the throttle and slowing down.

What you described is probably more likely due to cold oil and chain drag. You notice it if you start a bike on a paddock stand in neutral. The rear wheel turns until the bike warms up then it stops

Strange, never noticed it before. Even with the engine off and clutch pulled in it was hard to wheel the bike around. I'm sure it wasn't like that before.

I would be very surprised if the cold oil alone causes that much drag (unless you are using treacle!), sounds more like a worn basket and the friction plates sticking a little, which the cold oil will then exacerbate.

i might be wrong and you have a worn clutch or some other issue, but it wont be anything to do with it being a slipper clutch vs a non slipper clutch. That only works on deceleration

Check the cable.

Just figured I'd mention it was a slipper in case there was anything different about them.
I'll open up the clutch and take a look when I drop the oil next week.
