Should I use these over EBC or Barnet kits?
« on: August 10, 2011, 04:49:33 PM »
http://cgi.ebay.com/ebaymotors/Honda-Clutch-Disc-CB500-K-F-CB550-K-F-CB-500-550-NOS-/160616321191?pt=Motorcycles_Parts_Accessories&hash=item25657a90a7

I like the style of this friction disc over the square EBC and Barnett style, anyone have any experience or preference in this regard?

No one can see it when it's installed.
Why do you 'like the style'?
 Do you know if 'swirl pattern' works better?

Nope I don't that's why I asked  :)

I have heard from reading posts on here that the EBC and Barnett squared style ones tend to be more of an ON/OFF switch than a smooth transition.  But since I have 0 experience with rebuilding motorcycle clutches I thought I would ask for peoples 1st hand experience.

I have plenty experience putting clutches in cars, and know what the difference between a puck style clutch acts like vs a stock clutch.  I don't want a "puck style" clutch in my bike I want something with a gradual grab.

From HondaMan's FAQ:


Solution: today, the plates are available with square-cut cork faces. Find these and use them. And, replace the steel ones, too. They're warped if you have 10,000 miles on them, believe it. Also, DON'T run Valvoline or Havoline oil. These excellent oils overlube the plates and make them slip. Instead, use Castrol (best) or Torco (next best) oils. Castrol and Honda worked together in the 1970s to get the right blend: trust 'em.

OK, the 'swirl' plates are directional.
Put them in one way and clutch will probably work well for a long time. put them in 'backwards' and it will grab and wear out fast.
If you don't know which way they go, you would be better off with 'standard' plates.
 I like EBC, never had any problems with them.
Barnett tend to be pretty 'grabby' I'm sure they still use 'drag race' friction material.
 Personally, Honda make the best plates, they don't make the best springs to go with them though so I always fit heavy duty (race  ::)) springs
 I usually modify motors, stock clutch spring let clutch slip.
 I have over 106,000 on my '550' with ORIGINAL clutch plates (but I'm heavy on brakes and tyres  ;D)
BTW springs are a whole lot cheaper than a set of plates  ;D

the slanted faces when put in the right direction give you a long flat smooth clutch great if you are trying to teach your girlfriend but slow to lock up as it takes longer for the oil to squeeze out of the clutch
the straight faces give you more of a conventional feel
if you are drag racing and want the clutch to lock up instantly like a spline clutch then put the slanted ones in backwards

if you are learning to use the clutch or don't like to be tossed around or just like it smooth and easy put the slant ones in
the real week link is the springs  ask mark (hondaman) who he recomends for springs heavier springs will take some of the gentleness out of the clutch with slanted faces but it will still be very smooth
the straight cut faces with good springs locks up much quicker better for people looking to go fast that don't care about smooth
the 550 when it came out was touted as the smoothest bike before the gold wing in 75

the barnet corks wear and send abrasive particles through the oil system and has been credited with wearing out the oil pumps on sohc motors

I'm no expert, but I figure I'll add my $0.02 on barnett/EBC.  I built a 400F that was way too powerful for the stock clutch setup.  I heard the barnett springs and clutch plates would hold the power, but that the result might be a grabby clutch.  I ended up going with EBC plates and the barnett springs.  The clutch pull is not noticeably harder, but the clutch is smooth to engage, engages as quickly or slowly as I want, and does not slip at all.  I've even opened up more power with the engine afterwards, and the clutch holds fast.  I plan to use this combination on all future builds.  FYI, the springs cost $10 and the plates were $45 or so.  I bought them through cycle gear.

Thanks everyone just the info I was looking for.  Looks like a clutch rebuild is in my near future.  Just So I am clear it looks like I want EBC friction discs, honda (still available?) plates, and EBC springs?

I would think you'd want to sling oil off the plates so the outboard edge of the groove should trail in the direction of normal rotation. I'll just bet it comes with installation directions ;D

I'll bet it doesn't  ;D

One other critical point when rebuilding a clutch is smoothing out any indents on the clutch fingers. The clutch tabs can wear grooves into the fingers that can limit clutch forces, create false neutrals, make it difficult to find neutral and contribute to clunky clutch operation. I have addressed the issue by filing down the clutch finger faces on a few clutch drums.  I have seen no adverse affects from this operation yet.

Here is a video I took when I pulled my clutch cover off to polish it. 

Cb500 clutch free play

is that play normal? It seems loose as hell to me, but the clutch doesn't really slip if adjusted correctly.

Are you taking about the fingers, on the basket, like where my fingers are in the video?

It's about normal.
I shim them to about 0.010'~0.015", makes it quieter (if it was helical gear it would sound really bad when running)
 It needs clearance for oil flow
