What to do first?

Okey, I need some help to understand something.

I am currently looking at replacing my clutch master with a new one.
Been looking at several different ones, but the piston size has made me confused again.

I was under the impression that the bigger the bore or piston size, more power or pressure it will give.
Earlier today i did read on a description on a brembo clutch m/c with adjustable pressure, 16 to 18 or something. .

The description stated that setting the pressure to 16 you would gain more power, 18 is prompter but less power. ? Can someone with more technical experience please tell me the difference? I tought the higher the size the bigger the pressure or power is deliverd.

My current M/c has to be pullef all the way in to the handlebar to deliver any pressure to engage the clutch. What i want from the new m/c is minimum leaver movement to engage the clutch. I dont want to be pulling it all the way in everytime.

Cheers

Keep it simple to remember:
Smaller m/c piston = easier pull but a longer stroke needed to get the work done.
Larger m/c piston = harder pull but a shorter stroke to get the work done.

Fork question.

Did change the fork fuel today and stuble uppon a problem when reassbling it.
I followed the heynes manuall and compressed the fork, messured it, pumped it a couple of times to get rid of air, remassured it and top it of eith oil. When putting back the spring and the rod and top cap i was not able to compress it to screw the topcap back on.

I do figure out the rod had to be alligned correctly, which i think it eas. (No spring eas visible)
What am i doing wrong? I did put a lot of strengt into it..

Thanks George

I always like to torque bolts and nuts down to their correct torque setting. When i got the tools for it i might as well do it properly.

I can however inform you that change of fork oil was badly needed. I have never seen oil this black or this thick before!! And the amount of oil that came out suggest that the forks had waaaay to little oil in them. No wonder they did perform as they did.

Arnie i followed your addvice and sat the level to 140mm. Will test drive tomorrow and see how it feels and handles. Until my funds may acquire the fork valve and new springs, this will suffice for now.

With air cooled aluminum cased engines I think the TQ's are important to adhere to. Parts are easy damaged and expensive.  . I am running the stock forks at present and change the oil in them every spring.
