ST1100 clutch
« on: December 15, 2013, 04:37:02 PM »
Has anybody modified their clutch lever to reduce the travel. I have looked at shortening the rod into the master cylinder and adding a spacer to the stop on the lever. Drilling and tapping a bolt into the stop could acheive this. 5mm on the stop with the same off the operating rod might be enough. Make it easier for short handed people to operate the clutch. Thoughts please.
Ta very much, Sailor Sid.http://ozstoc.com/Smileys/default/think1.gif

Would fitting an adjustable lever have the same effect? HarrieG fitted one similar to this (eBay link below), well I think it was him (I searched but couldn't find the thread). He may be able to advise how it went.

Also, some info on the US site: http://www.st-owners.com/forums/showthread.php?91730-35-Ebay-Levers

I've thought about doing this myself.

Levers from VFR750 are adjustable and fit.

Just looking on EBay at the levers available for the VFR and lots of the ones available are pairs which would keep both levers the same. I'm wondering if the brake lever fits as well, this would give adjustable levers on both break and clutch.

I have fitted a pair of adjustable levers to one of my 1300's some time ago they are available off E bay you will have to do a search there are several different suppliers and quite a large difference in prices.
I have a note here that The CBR 1000RR is a direct replacement for the 1300 but is slightly shorter but fully adjustable. I know this is not an 1100 but the fitment guides will tell you of the correct one for the 1100.
link koczarski.com/ST1300ClutchLever.htm
Or failing that I thinkkthat I found my set on the Aibaba web site. They will probably have a listing for the 1100
happy hunting.

WELL I went ahead and did what I thought might work and it has so far been sucessful. I drilled and tapped a 3mm thread into the clutch lever stop and inserted a 3mm countersunk screw which spaced the lever in a bit, [forgot to measure] but it is much better for my hand now. I then removed the pushrod and cut 3 mm off the end, enough to give it some free play and refitted it. Haven't quite managed to get the sealing boot over it yet. This has given me much better control over the clutch specially at low speeds. A sucessful modification.

From memory as it has been a while since I did it, I took out the brass bush and took a couple of mm on the grinder. This will shorten it making the clutch take up point closer to the grip. It's not adjustable but it you screw up the brass bush is cheap to replace if you get it wrong.

Thanks Brock, might order a set. Should make a nice farkle as the stock levers look very drab, not sure if I like the ones that look like sharpened knives as that takes it just a bit far.

So am I correct in saying the VFR levers just fit straight on and theres no other fiddling required?

Thanks Brock, I'll mentally file this info away.

At the moment though my clutch seems to only work the last few cms of travel. Should I just get some new plates and bleed the clutch?

Most ST clutches only engage about 2 cm from the end of release travel.  Compare with someone else's bike before you go interfering with it.

Most other bikes I have had had some way of adjusting the friction point on the clutch. Having no method of adjusting the friction point to me seems a little pointless as everyone has a preference for setting up their bike.
You do get used to it but I prefer my friction point a little close to the bars, which makes slow speed trail breaking easier.
