Hey guys, I put new fluid for the clutch in, and mityvac it to bleed. Clutch engages close to the handlebars now with no lever change, whereas before i bled it it engaged almost towards the end of travel. Curious to see if this is normal with new fluid, or if i have air in the line, or it originally had air in the line before the change. It fully disengages when the lever is all the way, but the slightest release and it takes right off. Thanks for the input!
If by "lever in all the way" you mean lever pulled to the bar, then you've got air in the system.

Ahh ok. I guess keep bleeding then. I'm going to try "back bleeding". When using the mityvac , there are no air bubbles. Hard to beiieve this little line is giving me so much trouble haha.
You probably have an air bubble up at the master.
Have you bled the lever as well as the clutch?

I havent. I didnt realize that you could. I'm going to look up how to do it on youtube. So far i've bled almost 32oz through the system haha. I'm a noob.
Ok so....I tried 2 methods of bleeding the master. I tried priming it (holding my thumb over the banjo bolt and pumping the lever) i felt pressure and did it until there was quite a bit of suction, then re-attached the hose and bled. 2 i pumped the lever with the cap off and watched for bubbles. Didnt see any bubbles, although it squirted at me if i press the lever too quickly. both times i adjusted the bars so it was at the highest point, and even took the master off and had a helper hold it up off the bars and to be sure it didnt drain fluid. I am at a loss. Only thing i havent tried is reverse bleeding, however maybe between handlebar switches the master went bad?
Tie the lever against the bar overnight

On but loose to keep dirt out

So I checked it when i got out of work. It is improved from what it was but still close to the bar engaging. Do you recommend I leave it like that for another day or try bleeding the system again? Thanks for the help! [thumbsup]
I had to bleed two full cup fullls
Well I ended up doing a reverse bleed. $5 of 3/16 hose and free syringes from rite aid did what a $70 mityvac tool couldnt. I'm sure a case with no severe airlock, the mityvac is super easy.

I find the mighty vac good for changing the fluid, not so good for bleeding.

Yep.
I slurp the old fluid out of the reservoir with the Mityvac and it's canister, then hook the canister to the bleed nipple.
Fill the reservoir with new fluid.
Then bleed the normal way.
