Clutch replacement advice - PowerDubs_imp - 06-09-2022
Like any other clutch- it slips a bit on high load / hard accel. But unlike a car that has 1 friction disk in a dry hot environment- the is a stack of numerous layers of disks lubricated by the engine oil.

Your basket fingers could be worn. I don’t envision you to be hard on the clutch so doubt the metal disks are overheated and warped.

Ah, so when you refer to slipping youre talking about what feels like a dip in pulling power under hard accelleration.

You won’t notice a dip in accel- you will hear the revs go faster than normal in relation to your rate of accel.
Think of driving in snow- accelerate smoothly and all is well. Then put your foot in it a bit too much and the tires loose grip, spin faster than they should and the revs climb. Back out of the throttle a bit and they regain traction. Clutch slip is pretty much exactly the same.
My wife’s car is well known to have a clutch that is ‘just enough’ for a stock car. That being said- I’ve upped the boost pressure on her turbo because she doesn’t drive hard at all. No launches, no shifts during hard accel- so for her it’s fine:
if I drive it and roll into the throttle at highway speed to overtake, say about 3,000 rpm and half throttle or more- the clutch will slip, revs climb and I remember to back out of the gas, clutch grabs, and I continue at less throttle trying to remember not to do that.

Welcome to the Forum mattmcuomo1.

I have been aggressive on some past [Yamaha] clutches to get them past 65000 kms before noticing some excessive slippage. That is the "early indicator" Dubs is likely referring to. You will have plenty of opportunity to replace the subassembly and be on your way again Mr. P.

That’s good miles. How many times have you changed the clutch fluid and bled the slave cylinder?

Well at least all that info helps me to understand what to look out for. That sounds like a pretty odd feeling that would be hard to miss. Cant say ive ever felt a bike do that. Even a properly ancient one.
RE: Clutch replacement advice - GoldOxide_imp - 06-09-2022
In terms of excessive clutch "grab", I have experienced that, but not due to clutch plate wear, but because of an overheated clutch/hydraulic system - due to engine overheating. The Honda engine was air-cooled and just wasn't getting what it needed on a still-air, profuse humid summer evening in Toronto during a Caribbean Carnival. Once the engine had a chance to cool down (~30 minutes), the clutch resumed normal behaviour.
To be honest, in this particular case the "early warning" was quick - in terms of minutes.

Funny story- in my youth my friend had an old well used and abused dirt bike from the 70’s.
He had it out on the road, and was dropping the clutch to break the rear tire loose for burning rubber. Then I see / hear him doing it over and over again- then looking at the bike like something was wrong. I walked over- thinking he smoked the clutch- nope- the front sprocket teeth were completely worn away and the chain was just spinning on the remains.

lol - on an ADV forum I have seen a few "proud" images of that.
They seem to pride themselves replacing sprockets often (front and rear).
