Clutch Cover

[gary hyp]

Hi, I'm thinking of putting a slotted carbon fiber clutch cover, BUT only if there is a benefit to installing one.
I realize that the only reason would be to keep the clutch cool But is it nessasary???
What does the oem clutch look like in terms of style???? This is why I'm considering a carbon fiber slotted one . It still will vent cool air but not show to much of the oem pressure plate, assuming it's plane jane ( because everybody seems to run colored pressure plates). ????????????????????

I would avoid a carbon cover man, for the simple fact that if the bike happens to go down on the clutch side it will destroy the cover and possibly the internals of the clutch.

Aswell as keepin the clutch cool it also prevents clutch dust build up inside the cover.

If your goin to get a slotted cover id invest in some stainless steel springs and caps, last thing u want is for the oem ones to rust and the oem clutch plate isnt to cosmetically ugly.

Thanks for that, I've been thinking about the same thing.

You also have to deal with the extra noise from the clutch when you run an open cover. That's most likely a plus for most people, but it's too noisey for me.

There is no good logical reason to run an open cover on the street. However I find the bad illogical reasons more than enough for me Style and sound... I wouldn't do the CF, not enough protection for some very expensive parts.

Will stainless steel springs increase clutch pull at the lever or it being hydraulic actuated keep that in check? Do you have a name brand in mind ??

Venting the friction material dust isn't logical? Improved cooling isn't logical?

Only if your clutch parts are worn out or fit poorly.

On my former ST4s I ran an open cover with an MPL Tuning basket which had titanium inserts (to prevent impact concavity) and was machined to very precise tolerances, which fit my friction plates with almost zero margin. It was more quiet than any clutch I've heard, including closed covers.

I will be installing an NCR slipper into the hyper, and reusing the MPL basket. I'm interested to see how quiet that will run.

It's all relative, anyway. People still rolled their windows up near me when stopped at lights.

If spring stiffness is increased the lever pull will be affected, even with the
hydraulic actuator. I believe the SpeedyMoto spring sets are the same stiffness
as stock, but there is at least one commonly available brand that is 10% stiffer
than stock. You can get a lever pull reduction by changing the clutch slave,
though the tradeoff is it takes more travel at the lever to move the clutch
plate the same distance. But in general, any increase in clutch spring stiffness
translates over to the lever pull, whether cable or hydraulic activated.

Not necessary hence not a logical reason to spend the money. Nice benefits but not necessary by any stretch.
