Nev's Lock Up Clutch

[Toystoretom]

I have a slight issue and poor Nev must be busy or his computer blew up so maybe some of you lock up clutch owners can help me out.

When the bike is cold, and you get on it in first gear (not even really very much) the clutch locks up and won't allow you to shift out of first. You have to back off on the rpm's or double clutch it to get out of first. As the bike warms up this situation gets better but doesn't completely go away. It will do this in higher gears if enough power or rpm's are applied. It shifts wonderfully if you ride it like a granny .

My cable and arm are adjusted OK, and I have plenty of freeplay. When I installed the clutch I made a special jig to measure the release rod placement and seriously, I can't be more than a couple hundredths of and inch from the stock location. I used the stock springs (not Nev's heavy duty ones) and I never even removed the clutch plates from the basket, so those should be in there OK.

That leaves the shims that were supplied with the clutch. The instructions said to use those as they were found to work the best. Tell me you have to tear this down time after time to experiment with shim thickness.

I probably have about 100 miles on this clutch and the bike shifted wonderfully before. The reason the bike won't shift up is because the clutch remains locked under a load and at high rpm's. It downshifts perfect, no gear clash at any time.

Any ideas or suggestions?

Sorry mate,I carnt help youI would guess it is adjustment as the cables tend to stretch a tad but Im only guessing.
I used to **** up without using the clutch maybe 90% of the time(have you tried that??)
Hope you get it sorted

I'd agree with JD, if you're on it, always clutchless., otherwise you're trying to overcome the lock up mechanism and putting undue stress on the lifter piece and lifter shaft, one of which will give out shortly. I know, coz I did it.

Since then I;

Don't blip the throttle at lights with the clutch in;

Don't pull in the clutch at high revs, including changing up;

Don't slip the clutch, get it fully out ASAP and use the throttle to control acceleration;

Do let the revs drop more than I used to before changing down.

Hope this helps, if not a more knowledgeable person will be along shortly........

How are you trying to shift out of first? The lock-up does not shift like the stock clutch, and is not used for up-shifts, only down-shifts. Pre-load your shifter with slight toe pressure, and blip (close) your throttle to up-shift, same as you would on a sportbike. Should drop right into next gear seamlessly. Use same technique for downshifts, but use slight pull on clutch. I think you will find it's easier on your left hand to drop into neutral at stops, rather than holding clutch, but I could be wrong with you using the stock springs.

Remember NEVER, EVER pull clutch on missed shifts, and maintain critical 2mm free play at clutch lever. Mis-adjustment and over pulling of clutch lever will lead to rapid failure of clutch lifter shaft and loss of clutch at the most inconvenient time and place.

I learned all this the hard way...

I may not have been right about everything, but a smarter person did come along, so I was right about that at least.

I knew it was a safe bet coz most people are smarter than me.

There is a company that produces a clutch mechanism very similar to Nev's right here in the States. They are really popular in competition dirt bikes and, of all things, HD's. I've considered getting one for my KLR because when you are off road and in a, should we say, 'sticky' situation, not having to worry about clutching in real nice....gas and go.

The name of the company is Rekluse Clutch. I believe the website is www.Rekluse.com

F%¤#¤ Nev Clutch.

Today I finished mounting my Supercharger on my R3 2006.
I put in Nev´s lock-up clutch too, and everything was ready for take off, I did the final adjustments on the clutch, and it wouldent disengage, no matter how much i tryed and adjusted it......then the lifter shaft snapped........So instead fo riding my bike
I have to take everything off again, Supercharger, Cooler, water, Oil etc.etc...
I even upgraded the lifter piece to the "new" one, before I put the lock-up in.
My question is Shall i use stock number of plates, or shall I remove one plate ?
I am sooo close to putting the stock clutch back in, and then sell Nevilles clutch.
What am I ( and all the other customers ) doing wrong ?
Please help me out ?

Jan,
E-mail Nev. I had a few issues with mine originally and with help from Nev, and others, all is now well. It's worth persevering.
