I dont mind stiff, the magura helps that bigtime anyway. Im only looking for the plates / steels / springs anyway.
I just dont want the bastard slipping anymore

Great OEM feel............ Don't care about the feel
Low spring pressure........ Don't care if its ultra hard to pull
Wears like Iron..... Big plus
Its a winner..... Hopefully!
If it dont slip and lasts more than a year I'll be a happy camper

DeWayne puts more power out in his bike than anyone, he told me to stay away from aftermarket fibers and steel plates. he said the trick was always stock fibers and I forget what they are called, but its like a hard anodized aluminum plate, I think hindson makes them. I personally run ebc with stiffer springs, I intentionally used my '86 springs to get more preload, the pull is harder, but it gets more clamping force. DeWayne showed me a trick on my 125, then told me never to do it because its the wrong way, but he just stretched out my springs a little to hold off on needing a whole new clutch. The spring preload is a HUGE factor on clutch grab issues, maybe try stretching out your springs a little and see if it helps.

Im pretty sure I cooked it already, the last time I pulled it the steels were already blued, I changed the oil last night and it smelt horrific

Dwayne Jones claims he puts out more power than anybody but i do not think so. Last time i talked to him he was still using a FMF fatty that he modified and in order to make one of these go as fast as possible you HAVE GOT TO BUILD A NEW PIPE PERIOD!!! and use a minumin of 50mm carb on gas. so Dwayne believes he has the fastest CR 500 a Saber Tooth 500 would mop the floor with his motor. THATS A MOTOR.
Dwayne uses aluminum cryoed and hard anodized. I give him a lot of credit he loves motorcycles and knows alot.
I gave up on after market fibers a long time ago some may be better now.

yeah, so maybe it doesn't put out more than anyones, but it makes some kick ass power, has he shown you any of the vids of him racing? I used to crack up when a few guys would take him through the corners, then he'd take like 5-6 bikes through one strait away, really awesome to watch

Either way, he knows his shit, and that the clutch setup he recommends.

I was running steel cryoed,for somereason when you cryo steel plates they seem to grip better. that was my complaint with steel they did not seem to grip as well as aluminum. Cryoed they work greta but the extra weight is slightly noticable in the motor responce. I have never tried hard anadizing aluminum plates but I gave up on them because I could smoke a new set in a hour.

The carbon is arranged in blocks, not a contineous facing.
As a result, the loading per square inch is higher, and tons of oil flows through for cooling.

Tried 2 different companies over stock but this is in 20 years. In the nineties I tried Barnett and they tore my basket up with notches and then I tried some other I forgot what they were they came in a green box and they would get hot and exspand and my clutch would not disengage so i gave up on after market fibers. I never had a problem with after market steel.

OOOOO someone dissing the barnett clutch, I wonder who wrote this????
"
What the Honda clutch gives up in durability is more than offest in feel and performance"
This is a paraphrase of the common reply to the OEM vs Aftermarket questions.
I feel if you replace the aluminum plates with steel, and keep it adjusted properly the Honda clutch delivers both life, feel, and performance.
If you really need the abuse protection, perhaps your gearing or riding style needs to be addressed.
For those who really trash the clutch, and theres just no way around it, then aftermarket is the way to go. But these clutches often put greater stress on the basket and gears though. Dont be surprized if something else fails. Honda 125's are famous for breaking these parts after an aftermarket clutch was installed. The stock clutch was supposed to slip slightly to cushion the rest of the parts.
Also, countless good plates, springs, etc get tossed at clutch time. If things remain flat, and the springs are good often just a set of friction discs will put you back in business.
The only Barnett clutch I ever had was on a Kawi H-2. It sucked. Grabby and hard pull. Same complaints I hear regarding other applications, including the CR
I searched google for "barnett carbon clutch cr500" and this was the first thing that popped up

Keep reading dickhead.....
I go on to say that the Barnett Carbon is the only Barnett clutch I have used that has the OEM feel.
Dave Cook and I got them at the same time, like 4 years ago, and we still have them.
I hope your new clutch fry's too ....
