My mate Peter in Townsville pulled the gearbox on his bike, no mean feat as its part of a pretty impressive sidecar rig, and found this.

Nice catch as it wasn't far off blowing and Peter rides this thing all over Oz's Eastern states often visiting us in Bungendore via the 'Western Route' which includes large stretches of urine drinking territory!

Geez Pete, I thought I was lucky to catch mine before it blew up but that takes the cake. Was he having clutch issues ?

OH MY ! Not gonna do a duct tape and zip tie fix on that :shocked:

Wholly Crap!! :shocked: :shocked:

How many miles was on that?

Is that red dust or faulty heat treat.... :wink:

Jesus wept! Why is that always the first question asked by the paranoid who assume that every bike is going to behave exactly the same!
The twin plate clutch is generally pretty bulletproof. There have been odd batches of poor plates, it's luck of the draw. Also it will depend on how it is used. As I said this one is out of a big, highly developed, sidecar rig. It works a LOT harder than most clutches.

Apologies! that wasn't the intention of the question.
My V7 has 29k (Picked her up at 28k) miles on it and I just got a bit worried since I've been beating on it since I got her.

Do you know what brand clutch plate that is? What were the symptoms?

Totally different clutch assembly on the small-blocks, plate has shock absorbing springs built in, so you needn't worry about this issue.

It looks like what was installed at the factory. Fairly common failure of that type of plate when used hard. Softer engagement normally, but the possibility of failure is the compromise you live with. Normal warning of complete failure is the clutch starts slipping on hard acceleration - this indicates that one plate's center has already fractured and the one that's left is trying to do all of the work. When the second one fractures, you go nowhere of course. :laugh:

Have had 2 clutch plate failures as above on my Calis ( 1996 and 2003). Both bikes had about 40 k miles when it happened. Only one plate was sheared as in the above pics. In both cases the clutch would begin to slip at about 4K RPM. To my recollection they were Surflex plates. Stein Dinse clutch plates were used s as replacement in both cases
-
S'not a good thing to see.

Ok guys, I'm the only one so far big mouthed or ignorant enough to ask. Having never seen one before.... What is the damage so obvious to everyone but me? Seriously! Is it the non uniformity of the heating on the friction material ?

Shows my depth of knowledge, I thought it was a reasonable question..

Peter, the cracks around the rivets that hold the splined centre to the central 'Backing plate' that the friction material is bonded and riveted to. The centre is within a bee's dick of falling out. When that happens the outer part simply rotates in the flywheel while the splined centre sits still on the gearbox input shaft boss and the bits off metal running over each other make a godawful graunching noise and there is a 'Failure to proceed'!

Do they teach you guys these things in school, or is creativeness promoted so they come naturally?
:)

Bugger me ! My crummy eyes thought that was a pressing or some such. Thank you Peter, I'm a tad embarrassed that I needed to be told.
-
I think we need a sticky of roperisms with application examples
"Within a bees dick of failure"<= measureable, minimum service tolerance
-
African, or European bee ?
-
Well if we're going to get picky I suppose it should be a 'Drone's dick' but that too would be inaccurate as being an insect a bee only has a cloaca and no external genitalia. :grin:

This is of course the antipodean derivation. UK English calls this dimension a Gnats Cock - I understand that the US English version is slightly bigger :wink: :wink:

You guys are funny!

It's not very nice to make someone spit up their coffee this early in the morning! :coffee: :grin:

Seemed a reasonable question to me, too, and I don't think I'm paranoid about clutches .... ?

Size wise, my money's on the African one !

dont feel bad Huz I only saw it when I noticed the gap between a couple of the cracks:(

Here in the states I understand that to be the RCH.

When you say "you guys", what particular group are you referring to ? Aussies, Old Farts, AussieOld Farts, Expat Englishmen with rusted on wit and Aussie colloquialisms, or a strange brew of all of the above living in a beautiful backwater of the capital city of the best country in the world ??? The wit displayed by our man is fairly common here, but his example does gave a slightly lower pH reading than most...
-
I was referring to Aussies, but the other choices are interesting too. :) Litmus paper indicates red around him, huh?

That wasn't what I remembered from skool, so I looked it up. Almost sorry I did. :shocked: :shocked:
The flea, it seems, has got the contest won, relative to body size:
Far bigger than 'normal' fleas, a new breed has emerged which has a penis two and a half times the length of its body - the largest genitalia relative to size of any bug on the planet [source: http://www.mirror.co.uk/news/uk-news/billions-super-fleas-giant-penises-8888941 ]
Here's some more that I can't repeat on WG, but the article is interesting:
https://www.wired.com/2015/02/50-shades-wrong-disturbing-insect-sex/
I'm assuming this is all within the rules, since it's not human, IS science, and could possibly expand Pete's imagery, if not vocabulary -- assuming he doesn't explode in midair, as is explained in the article. :cry:
-
I stand corrected, although I'm going to wait until this evening and I've had a drink before I delve into the netherworld of an article that references disproportionately large genitalia and explosive mid-air sex!

It's a page turner. :drool:

Hmmm, maybe some buffer solution would keep him closer to 7.0. (beer?)

I have never used the 'bees dick' measurement, as it is such a large unit, compared to the universally accepted RCH, which is, I'm confident, the finest unit known to man.
-
I agree
When one experience something as close as RCH it usually comes with great fear and almost a near death experience afterward
-
What's RCH?

I don't know either Huzo. Must be a northern hemisphere thing. <shrug>

You can easily find out by using Google to search for "rch meaning". :)

Okaaaaay...... :embarrassed:

.003"

Better check your micrometers. I get.0015
-
Last "RCH" I checked was 0.0017" but it's hard to get a accurate measurement when they are moving
