runninn Posted May 12, 2016 Share Posted May 12, 2016 Bike sat 2months due to travel. What is the easiest bleed method to restore clutch firmness?i already tried the traditional bleed method and am thinking back-bleed next. Suggestions? thanks Quote Link to comment Share on other sites More sharing options...
Chewtoy Posted May 12, 2016 Share Posted May 12, 2016 The clutch bleed should be easy. But if you are having problems, and the lines and connections are not leaking, try getting a cheap vacuum bleeder from harbor freight to do it. Quote Link to comment Share on other sites More sharing options...
Zero Knievel Posted May 12, 2016 Share Posted May 12, 2016 For as little fluid as is in the system, I'd just drain the reservoir, put in fresh fluid, and flush it out. Quote Link to comment Share on other sites More sharing options...
redxxrdr Posted May 12, 2016 Share Posted May 12, 2016 Do you happen to have another bike with a cable operated clutch? A few years back, I was repairing a GSXR then jumped on the XX. I was sure my XX clutch was busted. It was fine, my expectations had changed. I have never had a problem bleeding the clutch, but it will never get firm like brakes. And yes, I spent a long time one day bleeding the clutch before remembering that. 🤔😡😡 But if you are sure that you have air,. A myTvac from Harbor Freight will really help. i usually have to put Teflon tape On the bleed screw threads to prevent from sucking air into the bleeder.

superhawk996 Posted May 13, 2016 Share Posted May 13, 2016 Having the bike sit shouldn't introduce air, something else is going on. Quote Link to comment Share on other sites More sharing options...
Redbird Posted May 13, 2016 Share Posted May 13, 2016 Does the clutch fully engage/disengage? If so, it probably doesn't need bleeding. Chasing clutch "feel" on a hydraulic clutch is usually a frustrating experience. Quote Link to comment Share on other sites More sharing options...
rc46 Posted May 13, 2016 Share Posted May 13, 2016 +1 A hydraulic clutch will never feel like a cable one. Big bikes usually go to hydraulic clutches to lessen the clutch lever pressure. Quote Link to comment Share on other sites More sharing options...
superhawk996 Posted May 13, 2016 Share Posted May 13, 2016 The only hydraulic circuit on a bike I've seen "make air" from sitting is the rear brake on SV 650s, seen it happen on two of them. Other models may do this as well. I believe the heating and cooling cycles every day manages to suck air past the piston seal in the caliper. The clutch and front brake having their masters on the handle bar and the slaves a couple feet lower keeps fluid pressure against the slave seals. YEAY GRAVITY!
