Question to the Stunters..

normanrc51 · 08-23-2010, 05:53 PM

So i just picked up a 2001 F4i for stunting and it doesn't have a rear hand brake on it. I was wondering, why wouldn't a clutch master cyclinder from like a RC51, TL1000r or something like those work? I have read about people using front brake master cyclinders and turning them upside down, but i am not sure if i want to go that route. Any input would be great thanks!

Thats what I have going on. Works fine for me man. I say go for it for now until you do something else?

The clutch master cylinder will work. They both are basically the same thing you will probably just have less force with the clutch master cylinder. I would assume the clutch is a bigger bore master cylinder. I won't go into all the details but basically how a master cylinder works is the bigger the bore the less force i puts on the brake's and just the oppasite for a small one.

I was noticing that clutch master cyclinders are usually 14mm bore and brake master cyclinders are 19mm bore.... so I am guessing that the bigger the bore the more feel/stiffer lever?

You will get more feel and travel from a 14mm master cylinder. A 19mm master will be stiffer. Its all gonna be personal pref. I am running a nissin off a 07 cbr1000rr and it feels pretty good. Not as stiff a the brembos, but not as much lever travel as the maguras. It's a happy medium. imo

Ming,
Are you running the clutch master or the brake master from the 1000rr?

Thanks

Ok the thing is when you run a clutch master the hand brake has to be on the top and clutch below it. with the radial master you can run the clutch on top and have a better feel. like ming just stated is sorta true. It all depends on your rear brake setup as well. I have had two types with four different masters. with the a single setup I used an r6 side radial master and it was a 16mm was very stiff, then swapped out to an 07 r1 radial master and it became very soft, now I run a dual rear brake setup with a 16mm master and it's like butter.. but the moral of all this is personna; prefferance But I can almost tell you now you will not like a clutch master on there if you are serious about it.

I'm running a clutch master for my handbrake and my clutch is on top.

I think the idea here is keeping it cheap. Yes, a dual caliper setup is ideal but pretty spendy. Same goes for radial masters. Running a clutch master can be done for very cheap and will work for learning. It can be upgraded later when money permits.

Ok so what is the difference between the GSXR front master, 929rr front master, and an R6, newer years of course.

Thanks again.
