Re: Clutch drags when hot
Thanks! I'm trying to keep it standard apart from upgrades such as Avon Roadrider tyres, braided brake lines, EBC HH pads, new aftermarket coils, HT leads, igniters, fork brace etc. It really does run well, and revs out / handles well
I did measure the EBC spring height...although thicker, they were the same height as the standard springs spec.
The standard springs I took out were well within the Honda recommended service limit too, so putting them back in may be a good option, as well as checking the damper plate rivets as previously suggested.
Re adjustment, unless this settles down, the lower cable adjuster has to be set at zero play at cold to allow enough lever adjustment to get enough play when hot to fully release the clutch....and even this is not enough to stop the dragging as it gets used.
Should I make the adjustments when everything is hot and has been dragging?
This would of course mean everything is really tight with no free paly when cold and setting off.

My FSM says 5/8 inch free play at the lower lever. I don't know because I've never owned an 1100.robin1731 wrote:Is that the way the manual says to adjust it?purgeraptor wrote:snip................ the lower cable adjuster has to be set at zero play at cold .

Re: Clutch drags when hot
I don't think the EBC clutch springs are a cause if the heights are the same as the Honda ones and I think there is possibly something else going on there. The correct adjustment of each section of the cable/clutch mechanism is definitely where you should begin to rule those out as a possible cause of the problem. The 5/8" freeplay is correct per the FSM for the bottom of the cable adjustment where it enters the lower case. I just don't see how you can see how much free play there is in the cable connector once everything is buttoned up.
There is also an adjustment in the very back of the rear clutch case for the push rod/pressure plate mechanism and the FSM specifies loosening the lock nut under the access cover plug and turning the set screw clockwise until you feel it start to tighten up slightly. Then to back the screw out one full turn and lock the nut back down on the set screw. This only adjusts the free play on the push rod assembly that pushes against the pressure plate. This area again seems not too user friendly once the motor and swing arm are installed in the frame.

Re: Clutch drags when hot
All that should be looked over. Probably said in an earlier post about going back and resetting everything from the start.

This was part of a post on the first page, which negates some of the adjustment procedure above... just saying.

Re: Clutch drags when hot
I see that now, so then the only adjustment is the cable which if when adjusted correctly doesn't fix the issue means that there is something else going on internally. That will require removing the engine to recheck the assembly and plates and scavenger pump for issues.

Re: Clutch drags when hot
Quick update.....fixed the problem
Changed the EBC stiffer springs to a good second-hand set of standard springs.
All perfect now.
Comparing the EBCs to standard springs, they are same length, but EBCs are wider in coil diameter.
This means the EBC springs do not sit in the recesses in the clutch housing at the base of the spring towers, therefor have a greater installed height.
Not sure why this makes a difference when the clutch plates heat up with EBC spring fitted, but it's certainly fixed now with the standard springs!

Re: Clutch drags when hot
Glad you worked it out. Hope I'm as lucky getting to grips with my starter problems, followed my the problem with the neutral light! Got some ideas to try particularly with the starter!
