I got the GP Tech handbrake setup last week and tried to install and bleed it. The problem is that after we bled the master cylinder and worked on getting all the air out of the system, it was sucking air from somewhere in the lines, which made it up to the master cyl and then bubbled out into the reservior. I reused the O-ring that was already on there, but there was movement in that valve thing when we were bleeding the line from the lever to the stock foot lever. Should I get a new O-ring or upsize it before starting the process again? Anyone else had a problem like this and fixed it? thanks

 

If the adaptor is held on with that 1 little bolt like on the 01-03 GSXR's it'll never hold the preasure without someother help holding the other side down welded my homemade adaptors on and their perfect

 

dude I own J&J powersports a bike shop in dillon sc and i got the same set up for my 954 and had the same problem never got it fixed they sent me about a thousand of the little valves but still no work my boy just made his own and his works perfect.

 

I was thinking along the lines of a gasket maker or something like that around the mating area.

and yeah, it's held on by that little screw on there.

 

That wont work unless its a cement or something that dries hard like JB weld
That fitting is under alot of presure dude.........if you can dissasemble the master and have the adaptor welded on or go nuts with JB

 

i might just JB weld it or see how we can get something going at the garage. might have to ghetto fab something

 

Ive seen people use a hose clamp and JB to hold it down and keep it sealed but I cant do things like that myself Im a "do it right the first time" kinda guy.........machined up adaptors for my 636 and my buddys GSXR and had them welded on for $20.

 

we have a few months left of riding then dec and jan off because of the weather. I'll probably do it right during the break and something fast and "good enough" for now.

 

i didnt have anything holding mine on but that little screw and on my 636 its just a C clip that holds it in never had a problem with either maybe its your master cyclinder some might be machined a little big dont really know. i would have to take a look at it myself to see what the problem is.

 

Dont know if this will help you any.

here's your fix.... www.fullthrottleinc.net

 

that **** leaked a thousand times worse than any fitting i've seen, sent it back to bill for him to "rebuild" it and it leaks just as much as before

 

+1 thats what I ran on my 900 and my Gsxr and had no problems with either one.

 

I'm gonna try something. I'm not getting a full throttle setup, maybe I should have gotten one from the start, because that's like 500 bucks for a HB setup with the two costs combined and I can't stomach that at all.
