The dry clutch on my 750 F1 is not completely dis-engaging. I have bled the hydraulics, with no improvement. Where should I look next?

I bled the hydraulics bottom upwards and top downwards with no improvement. The lever is adjusted for max piston travel. Is this a master cylinder problem or a clutch problem?

SOURCE: Long clutch pull/engagment on 696?

I recently installed CRG levers on our 696. No boot to fiddle with on this model. You can see the Allen key on the back of the lever perch from the outside or bar end. Simply adjust the Allen screw in/out with an Allen socket and ratchet to a range of positions then check clutch engagement and drag via a few test starts. Too far one direction and the clutch hangs up while too far the other way can give you an off/off switch lacking in full engagement that is hard on the gearbox.
Conservatively set after 15 minutes of adjusting and testing resulted in an incredible reduction in the distance that my wife had to reach her tiny hands. She was extremely pleased as this completely addressed her only real complaint and made it much easier to ride.
I did take the more expensive route with the Termi cans, getting a bit of a break from my local dealer at about $1250. The upside I found was that there really is no need for the dealer to install the cans because re-mapping wasn't necessary as it was with my 1098. If you are capable of unbolting your gas tank (a gazillion Allen screws on the tank covers and three bolts on the tank) and have a spare set of hands available to hold it so you don't have to undo fuel lines it is fairly simple. It's a good idea to take the tank covers off so you can see where everything is hiding. While you are under there with the battery disconnected I recommend installing a battery charger pigtail so you can easily plug in a trickle charger for the off-season. I spent maybe two hours - less time than on the fender eliminator.
Again as I found putting Termi cans on my1098 the 696 loses the irritating leanness, starts much easier (fast idle no longer necessary) and runs much cooler. Plus it's all covered under warranty. With the removable sound deadener inserts you have a much nicer sound in your choice of "mellow" and "heavy metal". In my mind it now sounds like a Duc is supposed to sound.
One trick on the install: the new CPU caused my dash to switch to EU (km instead of miles). There is an excellent detailed thread on this site that shows how to change back to US settings. Takes about two minutes.

SOURCE: Clutch pedal won't come back after fully engaged

You will need to rebuild or replace both the master & slave cylinders. Then bleed like a brake system.

SOURCE: Have overhauled the front master cylinder and

turn the handle-bar to the left and set the mastercylinder under pressure by holding the lever with a rubber strap to the grip
and leave the bike over night in the garage - next morning remove the strap and sure there will be a good pressure.

97 750 suzuki katana clutch engages but bike stalls out when shifting to first

In which case the clutch is not properly dis-engaging. Adjust the clutch cable properly, if this still doesn't fix it you will need to replace the clutch friction plates at the very least.

94 Chevy 2500 Clutch Engagement?

You probably have a hydraulic clutch. A hydraulic clutch has both a master and a slave cylinder. The slave cylinder engages/disengages the clutch plate. You might be low on clutch fluid in the master cylinder, or the system may need to bled similar to bleeding brakes. Worst case is you need a new clutch, pressure plate, and throwout bearing. They should all be replaced when doing a clutch job.

Does the clutch not engage( ie it slips & wont pull away) or does it not dis-engage (ie always in gear)
Was the clutch dismantled or disturbed when top-end was replaced

My clutch lever had a normal operating range, but now, after a 550 mile trip, I have to hold the lever completely down and only can release it about 1 cm before it re-engages. It basically wants to move...

If I recall correctly, this model is equipped with a hydraulically actuated clutch (it has a clutch fluid reservoir on the handlebars instead of a clutch cable).
If your hydraulic clutch is not building enough pressure to release the clutch, it might just need to have the fluid flushed out, and the system bled. If that does not remedy the situation, the master cylinder, slave cylinder and hydraulic lines would need to be inspected.

Clutch fails to dis-engage clutch. 1986 F250 3/4ton 7.5 2wd

Make sure the slave cylinder body is attached firmly, then bleed the air out of the hydraulics--similar to bleeding brake lines. Watch the clutch mechanics while someone operates the clutch, (engine off) you should see definite movement. If you get movement and no clutch action, you may have to reappraise your clutch installation. Hope this helps!
