Title: Dry Clutch-a-doodles
Post by: He Man on March 16, 2009, 04:16:03 PM
My dry clutch is dead at 9700 miles. :( all the city driving and burnouts didnt help i guess. The only plates i can find are made by barnett. do i have any other options?

any reason you dont like/want barnett? 

Chris at cacycleworks has the barnett clutch for $150.

Just for the record, my Vespa GTS (pimp'd with Brembo brakes and LeoVinci pipe) can go 80+mph.  [roll]

Is 9700 miles normal wear time for a dry clutch or is it a bit premature?

intercooled rotary GTR limited edition? :o

Premature depends on what you base it on. Im slipping the clutch in one day more than you would in month because i ride in NYC. my friends wet clutch also died around 14k'ish or something. so.... its all relative.

i have close to 12k on mine, and its doing great.
little to no city riding though.

again, preamture is all relative to what you compare it to.

What are you basing premature on?
How many miles do most people get out of a clutch when riding strictly urban bumper to bumper traffic?

If you aren't seriously doing the rough stuff you said earlier, wouldn't stiffer springs alleviate some of the clutch life issues?  Admittedly by forcing you to go fully engaged more often, but hey, dry clutch bikes aren't meant for a lot of that.

it would, but they only go so far. i already have speedymoto stainless steel springs that are stiffer then stock. looks like the cheapst option are barnetts, hopefully these will last more than 10k miles :(

I remember a guy that switched to aluminum basket/ plates and he mixed brands and got nearly a perfect fit (after filing them because the tangs/ openings in the basket weren't the same size  [roll]). It reduced chatter to almost nothing but I don't remember if it increased the life span of his plates. Anyone remember?  This reminds me that I'm due for a new clutch pack very soon. I keep forgetting when I last replaced it. I don't keep very good records.  [roll]

i think the correct term for these things are clutch packs. im ordering the barnett ones, cheapest i could find.

It depends on how worn your basket and hub are and how you ride.

Wait till you get to 30k, like I did with mine.
It sounded like an automatic weapon.

I can think of one New Yorker who has about 36K on his dry clutch, basket and plates are notched badly, but it doesn't slip yet.  59K on my wet clutch.

maybe i should just stop holding in the clutch at lights and doing burn outs. :P

I ride my S4 like a dirtbike, clutching the front up, lots of slipping when making u-turns, and turning around in town, and generally not babying it a bit.  There's 12k on the bike, just bought it, I'll post up on any problems I have with it.

Title: Re: Dry Clutch-a-doodles
Post by: He Man on March 19, 2009, 12:22:50 PM
i will defend myself only by saying, i am doing burn outs because im trying to kill my tire. i didnt realize doing a 3-4 second burn out for a total of maybe 10 times would take its toll on my clutch. :(

i h ave a brand new tire sitting ontop of my closet waiting to be installed.  :)


anyway, i got the new barnett ones, it has a orange like pad on it. took out the old plates installed the new ones. bike starts up and cycles through all the gears without grabbing the tire, so it looks good, gonna have to wait until the rain settles to ride it though. the old plates were toasted. all the plates pretty much looked the same. friction material was completely gone.
Title: Re: Dry Clutch-a-doodles
Post by: erkishhorde on March 19, 2009, 12:39:39 PM
Nice to hear that they went in well. There's something about my clutch that's funny and I can never put the recommended plates in. I always have to finesse the stack height by swapping out steels. What model/yr bike do you have?
Title: Re: Dry Clutch-a-doodles
Post by: He Man on March 19, 2009, 12:51:42 PM
i have a 2006 S2R1000. i coudlnt figure out what the deal was with that curved plate. it just looks like a regular steel plate with a slight..uumm curve on it. lol its suppose to be in the middle of the pack, but i coudlnt find it on my OEM plates. it might been banged up straight though.

ive read some reviews on the barnetts and stated that the friction material does not like water. so no more hosing the clutch plate.

I can never figure out the curved plate either. I know which one it is, but can't tell which way it goes. I'm not sure it really matters as I've had my clutch out several times and it always works well when I put it back together. There's NO WAY I did it right every time!  [laugh]
Title: Re: Dry Clutch-a-doodles
Post by: erkishhorde on March 19, 2009, 04:12:12 PM
The curved plate is just meant to help the pack separate AFAIK. Over time it gets flattened out so it's hard to pick out of an old stack.
Title: Re: Dry Clutch-a-doodles
Post by: He Man on March 19, 2009, 07:32:31 PM
eh. i just threw it in there. lol

went for a ride today and oh my, i stalled the bike for the first time in a while  :-[ the clutch grabs the momment you ease of the clutch, but the front end comes up in a jiffy.

I've got 16k on mine, no issues and really, it could be LOUDER for my tastes. Heh.

Another option for anyone stumbling across this thread would be the 48t baskets/plates. I believe it is supposed to have a longer wear-life, but I have no FHE. Also supposed to be quieter, and I suppose it depends on who you are, whether that is a good or bad thing.

QuoteI can never figure out the curved plate either.

Me neither.  Maybe the spring action is supposed to make the clutch action a little smoother.  But there's already plenty of springs in there.

Post by: Howie on March 23, 2009, 08:57:24 AM
The curved plate acts like the Bellville spring in a car clutch disc, making application a little more gradual. 
Title: Re: Dry Clutch-a-doodles
Post by: erkishhorde on March 24, 2009, 10:57:59 AM
Remind me again please...

Mixing steel basket and aluminum plates is bad? If so, why? Does it just hammer the aluminum a lot and wear unevenly/prematurely? Also, if that's the case, there's essentially 3 parts on the clutch: the basket, the clutch pack, and the hub. If you decide to go aluminum, should you change all 3 or can you get away with just 2 (pack/basket)?
Title: Re: Dry Clutch-a-doodles
Post by: junior varsity on March 24, 2009, 11:05:00 AM
I don't think most people change the hub when they are replacing parts. It doesn't show anywhere close to the wear that the basket does from the plates getting slammed to-and-fro.

Besides, its another 2-300 bucks, at that point you can nearly buy a complete slipper and drop it in (if you were doing basket, plates, and hub)
Title: Re: Dry Clutch-a-doodles
Post by: erkishhorde on March 24, 2009, 11:11:39 AM
OK, so I'm gonna leave the clutch hub stock then. How about the basket? I've got an old stock basket that I replaced a year or two ago (can't remember). If I switch to the aluminum Barnette clutch pack should I also switch to an aluminum basket?
Title: Re: Dry Clutch-a-doodles
Post by: junior varsity on March 24, 2009, 11:38:49 AM
I don't know if you "have to". If you've got the money, its lighter and spins up easier because of the reduced weight. Also looks purty if you've got an open cover.

But as far as "have-to"? I have no idea.
Title: Re: Dry Clutch-a-doodles
Post by: erkishhorde on March 24, 2009, 12:38:53 PM
And what are the benefits of light clutch pack? Faster response to throttle changes?

You don't have to if the basket isn't too grooved, but Aluminum plates will wear out faster with a steel basket. The whole softer metal banging on harder metal thing.

As I understand it, the benefits of Aluminum are quieter clutch and less rotational weight (quicker throttle response). The downside is that Aluminum wears out faster.
Title: Re: Dry Clutch-a-doodles
Post by: junior varsity on March 24, 2009, 01:59:03 PM
yes, plus rotational weight removed makes the bike feel lighter just about everywhere. like removing mass from wheels, flywheel, etc.
