slipper clutch

[Ozmoto]

Well I finally got my slipper today, Hinson... looks neat, just waiting on new plates & discs & should be good to go.
Anyone had any experience with this brand ?
Comes with 3 different spring rates as such ( actually a washer )...
What do the different tensions do in relation to the thing slipping ?

[Muzzard]

The washers if you have more than 1 usually are like tightening the clutch hub in effect.
The thicker the washer the tighter the hold on the clutch pack, the thinner the washer the less the tension on the plates.
This is my basic laymans understanding of what I believe is a bit of a crutch in motard stakes.
You should practice to the point it makes no difference where/what you are riding, the left hand can pick up the 'feel' needed to make the clutch operate just like a slipper but with more control ;)

Slippers go under your bed mate :lol:

[Ozmoto]

Yeah but you know what you are doing, I dont have a clue,hahaha.
when I back it in, I can get the ass out, down a few gears, everything is going good to this stage, then I let the clutch out, get massive amounts of hop, and its difficult for me to control it. I know you are meant to feather it but there is so much going on I can never get it to stay smooth.Looks all a bit gumby, grip,slide,grip,slide... anyway I thought it might make it a bit easier to control....and as for this supporting the local industry ????
I could have got this setup cheaper from the states as a punter than what it cost me buying here, and I work in a bike store... go figure....
And Muzz (Grumpa), you can have all your slippers lined up beside your bed, dressing gown draped over the foot of the bed & your pipe on the bedside table... :lol: ;)
My slipper is going in my bike... :P

Mate, can't believe you want to skimp on brakes, but buy a slipper. :?

They are nice though.

[devo]

Oh, and extra preload (thicker washers) on the secondary springs will increase the engine braking.

[Ozmoto]

Skimp on brakes ?????
Wot the ???
I had very little to go on when I got my brakes, Maguira (spelling) were just too dear, could have got a 4 pot brembo but with a solid disc ???
When I looked up what people were using , Motomaster actually got great revues, most of the major teams were or had used them.
Only thing I am short of is a radial master.
Anyway, everyone is entitled to an opinion.

Devo this is the setup I am using & a flame rear...
Are they pretty ordinary are they ?

Adam Altham swears be his slipper clutch as do a lot of top guys, but then some other pro riders don't like them. Really is personal preference and riding style I suppose. I've ridden Adam's bike off road and quite liked it but the clicking on the lever when it's pulled in is weird until you get used to it. If I had the money I'd probably get one cause it's one less thing I have to worry about, especially at the end of the day when my poor wittle hands and fingers are tired :roll: .

[albonator316]

looks like a good set up to me oz :D
whats a slipper clutch for a yamaha cost these days?

[Ozmoto]

STM's are a bit cheaper but after talking to a few guys (sponsors & racers)
they convinced me the Hinson was the way to go.
$1600 retail.... :shock:
I got mine a few hundred cheaper.
Could get one from the states landed for bit over a grand....
we are all smarter in hindsight....
Hopefully goes in this weekend, then I will be testing the abrasive qualities of my new leathers.... :lol: :lol: :lol:

I was under the impression you had settled on running your MX caliper. My bad.

That clicking is an STM thing Woolf.

[Flash]

I'd love to try one in MX

[Ozmoto]

hey devo tell me this, if I use the thinnest washer will I be in effect reducing my engine braking by how much ? I love 4t's but I do miss the feel of a 2t when backing off.
would the middle washer be the same feel as standard type clutch or the thickest one ?
I have no idea about any of this. because I am going to try to race this year I need all of the help I can get to try to get around without falling off.
Hence a slipper, my backing in technique is a little wild... you will know what I am talking about in late April....
You know the old saying "the older I get the faster I was " :lol:

[Flash]

Don't worry about backing it in, it will happen when you start going fast!

"STM"? :?

STM is a brand of slipper clutch Dean.

What Markee Mark said. Others might do it too, but I think most don't.

As you increase preload (or spring rate) of the secondary springs in your slipper, the amount of back torque before the clutch starts slipping increases. But your slipper can't give you MORE engine braking than a standard clutch, only less or the same. A thin washer (less preload) will allow your clutch to slip more easily, giving you that 2 stroke feeling. Even the thickest washer will likely still allow some slip.

Try 'em out and see what you like, then later on, see which gives you the best lap times.

+1 on forgetting about backing it in for now.

Took the old girl for a spin yesterday, just a short burn around the block
Dont have any ADR stuff on it anymore & covered in numbers so the local constabulary would love to see me out & about....
But I liked what it did, I now understand wot its all about & it feels good.
But the biggest difference I can see is the stress it will be taking off my
motor & tranny...plus it feels smoother when you let the clutch out.
1 happy customer....
Obviously with it slipping more will it shorten the life of my plates ?
Any ideas by how much ?

[albonator316]

yes the longevity of the plates are reduced, which would also depend on the amount of slip. Also depends if you use the clutch, if you bang it down gears with not clutch then the slipper is doing it whats its suppose to but more friction etc. never had a slipper clutch so can't tell you an exact amount.

[Flash]

Like Nick said it will shorted the life but ti will depend on the use/abuse it gets!

The idea behind its use in SM application is to be able to setup the clutch to suit the track and the gearset you have chosen to run with.
If you have very tight tracks that have 1st gear corners you would set the bike up 'light' to roll in under 3 down changes without chattering.
To be able to shift the gears and then just release the clutch as you load up the front will make the bike slide by slowing the wheel speed only enough for the clutch action to take place and allow engine RPM to match as the bike decelerates.
An open track would see the clutch tightened up so as to allow for better engine braking as you roll off rather than brake into corner entries ..
Comprehendo?

Yes it will shorten the life of the plates.
How long is a piece of string? ;)

As a goal for your clutch plates?
Nearly 100000Km and 4 years in mine using the left hand,
Slippers go under yer bed,
All together now,
'Your slippers go under yer bed'..
OK :lol:

[Ozmoto]

Thongs buddy... and I'm not talking about the G string types either... :lol:
I have to join the Townsville club so I can get my competition license.
Even though i have held an MA license before I have been told I have to
do a "competancy"test before they will let me join...
Pay for a day license & entry fee & joining fee so I can come home & apply & pay for my MA license....
Wot the ???
Is this the norm for you guys down there ?

[Muzzard]

Yeah sort of JD :?
I suggested fellas here join the Harley Club of Victoria for the best advantage to some licencing and cheap dirt track racing on a motard (which is not that far from a good setup) because of the expediency with the admin.
Some Clubs are sticklers for the 'rules' and part of that also says if you hold a road licence you do not need to do the riding skills part.
You will still need to do the MA licence tick and flick test and return it by mail.
