The fsm tells you how to adjust the clutch pedal. And to make it a bit stiffer take off the bias valve down by the trans. If that's already gone then get a clutch.

 

there is some room to adjust the pedal to your liking but if you go too far you will be riding with a partially engaged clutch the entire time and that's no good. As far as stiffness goes ZIGGATRON is dead on, assuming you don't have any leaks( internal or external) in the hydraulic clutch system.

 

Not meaning to thread jack, but, how can u make that annoying Squeak from the clutch pedal stop ? WD lube her ?

 

The clutch travel adjustment doesn't do too much and you have to be careful that you dont set it too little so that you are constantly riding the clutch. Otherwise, clutch travel can be determined by the kind of clutch/pressure plate you decide to run. Some PP can give you shorter travel than others depending on the design.

Lube doesnt help. Best bet is to purchase a replacement bushing for the clutch pedal thing. Google "clutch pedal squeak" and youll find the part number for the bushing.

Mine tends to squeak a LOT when temps go above 45* ambient. Below that, its silent.

 

Thanks unreal-
Gonna try a quick fix for now till I actually get some free time to do it.

 

To OP, I found a thread from Nico forums that may be useful to you. ( Dont worry about the title, If you open the link and scroll down, You'll find an adjustment pic probably from the FSM.
I was gonna upload, but it said the pics dimensions won't work here.
