Clutch replacement question

So I noticed the other day my clutch is slipping in 6th gear. Every other gear pulls fine except 6th. The bike has 35,300 miles on what I believe is still the original clutch.

Can I just replace the friction plates or do I need to replace the clutch plates and springs too?

The bike has done a handful of trackdays but isn't abused or ridden hard. I suck at wheelies too, haha.

The clutch plates can be visually inspected.
If they show signs of overheating (bluish sort of color) then it is better to replace them.

Springs can be measured if they meet the service manual's standards...if not, then renew them.

I recently replaced my clutch. I priced out OEM discs, and found out I could get a whole Barnett kit for less. The kit has plates, friction discs, and springs. It was a dramatic improvement after the old clutch slipping.

Is the Barnett kit any good?

I had a talk with a friend who uses Barnett's springs on track days and had the best of impressions on them but he told me that under stress, the Barnett friction plates were toasted so he went back to OEM but he kept the springs which are better than the OEM.

So.....are the plates any good and reliable?

Personally I have had nothing but bad luck with aftermarket clutch plates EBC and Barnett to name a couple.

The EBC's just plain wore out too quick and the Banett started chattering on hard launches, took the clutch apart and found large sections missing off of the friction plates.
Found the pieces laying in the sump and a piece in the oil pickup...I won't use anything but stock anymore.

Is that so.....good to know. Thank you nobody for sharing!

I hope you know that the friction plates need to be bathed in engine oil before you install them and a 30-50 mile breaking in after the installation without abusing them. Same procedure like the brake pads.

Would you consider the above a possibility on why the Barnett broke apart?

I am not asking about the EBC cause a know they are shit!

Nope proper pre installation procedures were used, plates soaked in fresh oil for a few hours in both cases of the clutch plates falling apart.

The first bike was a 300hp FZR1000 drag bike the Barnett chattered hard so I knew it would not last.
I was dumb enough to try the clutch plates again on my 929 thinking it was because of the high horsepower drag bike. No same result friction material falling off in large sections.

I will stick to OEM.

I have under 10,000 miles on mine. It's been fine so far. I noticed that I would get some chatter when down shifting in the last days of my OEM discs. That has gone away and stayed away with the Barnett. Seems to perform as I expect it to.

OEM on the left, Barnett on the right.
OEM uses 6 discs and 7 friction plates, where Barnett uses 7 discs and 8 friction plates.


Barnett springs on the left, OEM's on the right.

Yeah, I was quoted $120 for the full Barnett's kit with springs, not including the judder spring or judder seat of course. I went ahead and ordered all the clutch plates, friction discs and the judder stuff from Hondaeasttoledo for $146 shipped. The springs were all in spec, so I did not order those.

The bike is going for sale in the next week or two and I'd rather the new owner get the oem stuff that I know will work.
