So I've got a pulsar running 360bhp. It has a very heavy clutch pedal. I don't know what clutch is in it. Due to health issues I'm really struggling with the current clutch. Does anyone have any recommendations of a clutch that can handle the power but really need a light pedal. The car is only ever used on the road and rarely has hard launches
Any advice will be greatly appreciated

How heavy is the pedal? Why did you not fit it?

Not that heavy, exedy clutches are heavier I bent clutch fork and release bearing with exedy

Just bought it to fit my black car and swap out exedy but head gasket has gone so now that cars parked up in the shed, the helix clutches have a long waiting list, I had to wait 16 weeks for the first clutch which is in my white car, and about 12 weeks for this spare clutch for sale

Funnily enough I have thought of selling it because of the clutch. And my other car is an automatic! 😂

I would consider a CC segmented 8pad sprung centre friction plate and match it to a quality light cover plate, which probably be the Helix cover.

I'm sure when I did a search on here that people have had issues with cc clutches. Someone has suggested a smaller bore master cylinder so I'm going to try that first and see if that works

I've not had issues with CC clutches yet, they not bad and I have used most options over the decades .
You get people complaining about most brands with clutches and lot of times it bad fitting and not resurfacing flywheels .
You could try change hydraulic ratio, pedal travel stroke will increase fair bit, I made a custom slave for a evo race clutch that made clutch lighter and improved bite control .
generally easier enlarge slave piston diameter if master got surplus stroke cope with it.

How did you make a custom slave? I would need to know the existing bore size and presumably find another model that has a bigger bore

+1 for getting flywheel re skimmed before fitting clutch

sorry for late reply but my part of the world been a bit crazy .
In my case I machined it from billet as it a custom hydraulic release bearing .
On the GTiR options could be finding something bigger or machining bore bit bigger and making a piston or completely machining new slave as they pretty basic .
your limitation is on the master fluid displacement so some checks/maths need be done see what bore increase is achievable off standard master .
You can also look at moving pivot point on pedal slightly as way gain leverage .
simplest route is quality cover mixed with pretty grabby friction disc and flywheel A1 finished .
