Title: Kevlar or carbon fiber clutch discs ?
Post by: Farm boy on August 30, 2019, 09:33:00 PM: I could use some expertise on this. I am sure they both have their place. Bike: '03 se road king 103 - 128 tq / 107 hp. Has stock clutch, not holding when on it two up. It's only slipped a couple of times. I am careful now, when getting on it.
Anyhow, am planning on going with Barnett extra disc set and possibly the coil spring conversion. The extra $200 for the scorpion clutch is not in the budget at the moment.
Which is going to be better for 2up touring ? :nixweiss:
TIA,

I’ve got the extra plate Kevlar with similar power what you have and it still slipped a little BUT I’m using the stock spring, solo riding.
You May be ok with a stiffer spring with 2 up.
Keep us posted on what you decide, I’d be interested.

Post by: Smoketown on August 31, 2019, 09:20:09 AM: How many miles on the clutch?

Is it properly adjusted?

How much friction material is left on the disks? Check your service manual. There is a minimum thickness just like your brakes.

What oil are you using in the primary? Some oils tend to be 'slipperier' than others.

A stock clutch can handle quite a bit of hp and torque. The main replacement parts discussed on most forums involve springs and (for the lack of the proper term,) the outer pressure plate.

Now, if your clutch has reached the end of its useful life, ANY Barnett clutch is a good way to go!

I don't have an 03 RK service manual so, I don't know either ...

I DO know that my 2013 Touring Model Service Manual has instructions for clutch adjustment even though the model that I have come STOCK with a hydraulic clutch.

I had to buy the danged "supplement" to verify that it was "non-adjustable" ... Gotta love the MOCO ... :soapbox:

No adjustment for hydraulic clutch. Instructions for bikes with cable operated clutches don't apply and the adjustment mechanisms (at either end) don't exist on the hydraulic clutch bikes.
