Clutch slipping

[Supercharger_Mark]

I need some advice; the diaphragm clutch on my bandit 96 is slipping.
I could just put a new set of clutch plates in and that might make a difference.
Is their an aftermarket heavy duty clutch kit available?
I believe you can fit another diaphragm in but it makes the clutch leaver very heavy and I prefer not to do that, and the other option is to put a coil spring clutch in, and if so will it fit straight onto the shaft? And are the 750s the same as the 1100s?

[Deano]

put a coil spring clutch from a slabby in it mate. junk the complete bandit clutch system. get a gsxr diaphram clutch basket (1127 throught to the end of 1074 watercooled are all the same)
get a slabby coil spring drive hub springs and pressure plate, put the bandit alt and oil pump drive gear on (staight swap fit) all gsxr1100 clutch plates and steels are the same, make up a small spacer (about 8mm) to space out the clutch nut from the drive hub, put a 11-11.5mm steel ball up the guts of the clutch shaft to space out the clutch push rod.

i have just put a coils spring set up on my turbo bike, it is a 2004 bandit motor and it was as easy as it sounds.

750 is a alloy clutch basket - no good they destroy themselves at just a hint of torque and they make a great mess of the inside of you motor. cast alloy everywhere

im not really advanced just yet but man .. i though I.T was hard to understand .. what Deano just said was like reading a blank piece of paper...

soz OT

^^^what he said! I never really new how much i didn't know about bike till i got in here. Now i realise I am a complete novice. :(

Cheers for that deano,I have a couple of Q's, you said, (get a gsxr diaphram clutch basket).If I get a complete coil spring clutch from a slabby, wont that basket fit? And I assume that the Bandit diaphram basket must be differant to the gsxr one.

[Deano]

Mark the slabby basket has either 1 tooth more or less than the diaphram clutch basket, because of the differnt cranks in the 1052 versus the 1127. you will need the same clutch gear tooth count as you are taking out of the bandit motor. the bandit basket is a completely differt design, it has smaller plates and drive off the square teeth on the outside.

this is a complete slabby clutch that i brought, basically you will use everthing in the pic except the basket as it has 1 tooth less that the bandit/gsxr basket.

[Deano]

this is a pic of the bandit and gsxr clutch baskets. the bandit one on the right is smaller and completely different design

this is a bandit clutch plate sitting on top of a gsxr clutch plate.

the bandi on has a lot less friction material on it. note the differet ways of driving the basket on the outiside of the plate. the bandit plate is alloy and the gsxr is steel

the spacer that i mentioned is to space out the hub nut that hold the clutch on the shaft. the width of the splined hub on the slabby is about 10mm narrower so that spacer is needed as you run out of thread on the gearbox shaft,

the oil pump and alt drive gear on the back of the basket will come off with the use of a screwdriver either side, you will need to use the bandit gear on your gsxr diaphram clutch basket, the needle bearings and sleeve are interchangable between bandit and gsxr, not sure about the slabby bearings as i just used the bandit ones as they were only 4000km old

[Supercharger_Mark]

Thanks heaps for that info Deano, You've saved me a lot of time and probably money too.
Cheers
Mark.

Nice comparo Deano. I never realised the Bandit unit was so different to the Gixer.

[Deano]

no worries mark.

gix - bandit cluches are not much chop compared to the gixxa version.

[APE Dustin]

Ok, I got to ask. What is a Slabby? I can't say I have ever heard of it before. BTW this is some really good info to know.

[sickboy]

early model gixer,because of its 'slab'shaped sidecoves.

Just to jump on this.... what's the difference between a slabby and a slingy? Photos please.

In streetfighter terms, the slabby has a more angular frame Like Mark's

And the Slingy has a rounder frame

as large said, and the slabby is 1052cc and the slingy 1127cc

Top post Deano. Well done.[8D]
Can we put this, or a version of it, into the HOW TO section?
Im sure its come up before?

There is a HOW TO in one of the SF mag's if I can find it,
it mentions using the different size ball bareing to fine tune it
and gives the spec for the spacer.

I had problems with my B12 clutch,
Ended up using one stock clutch spring and one heavy duty.
Made the lever heavy and was only just about OK.
Ended up doing "home-made" progressive NOS because even an extra
+60hp would make the moddied clutch slip if it came in to hard.


Again...
Good Post...[8D]

The diaphram springs can be beefed up with spacers too, about 1/2 the difference of adding another diaphram for adding a similar thickness washer inside and out.
Diaphram springs test at ~100psi each preloaded to nearly flat.

Found gsxr1k valve springs are a good upgrade on coil spring conversions on my srad gsxr750
std springs read about 50 psi on a valve spring tester at 30mm installed height, 1k valve springs read 55 but if you add a 1mm spacer the std springs stay fairly much the same and the valve springs gain nearly 10 psi, with about 3mm available till coil binding would be a prob on releasing the clutch.

Cheers for that guys. This is now a page in the HOW TO Section: http://www.streetfighters.com.au/ASF_howto.asp
