ZX12R clutch pedal pressure

Good morning lads. My ZX12R engine swap is almost done now but i require a few suggestions to this.

Ive fitted heavier clutch springs to the engine and fitted a custom cable to operate the clutch. I modified the bike engines clutch arm that pops out of the gearbox casing. I cut the arm off and rewelded it 90 degrees out so my cable route was straight from the pedal. i kept the arm the same length to not alter the ratio or movement from the pedal to clutch arm.

Well now i have sat in the car and used my foot on the pedal (instead of hand when building it) i cant get over how light the pedal is. I dont like it either. Is there anyway to make the clutch pedal heavier without loading up the cable (dont want to add extra pressure to the cable nipples)?

I thought about getting a clock spring and fitting it to the pedal pivot, is this a good idea?

Any comments welcome.

Andy

after a few hours stuck in rush hour traffic you'll be glad its so light. My landys and the SAAB were so heavy I could hardly walk afterwards. Within no time at all you will get use to it, try it on the road first before making up your mind.

As above. You really need to try it on the road first. My R1 clutch is very light also but I would rather it be light than heavy. You will soon get use to it.

Somewhat off at a tangent, but has anyone with a BEC tried using a lever for the clutch like on the bike installation? I was thinking that you could mount the original clutch lever on the gear stick, then you could do clutch and gearchange in one go.

Good idea?
Stupid?
Thoughts?

(thinking about it, there might be SVA issues, but it was really to see if it was technically a feasible solution)

No reason at all you could not do this but I think it would mean your hand was off the wheel for far longer (due to the clutch having to be depressed, then the gearshift move, then releasing and feeding in the clutch), for me when driving my foot is pressing the pedal up and down for much longer than the time it takes to move the shifter.
