Softer clutch springs

[dxhall]

It’s looking like the LM V needs new clutch plates.  While I’m in there, I’m tempted to put in a set of the softer springs offered by MG Cycle.  Here they are:

Anyone tried these?

The weaker spring should work ok
Another way to go I have seen on an Airhead, a pulley mounted on the clutch arm halves the pull required but it also halves the arm travel.
I don't know the name of this device, If I recall it had a small chain around the pulley.

I bought a set, installed them, but didn't get a chance to really try them. Long story there.

The lever pull was nice with them. If your not a racer, maybe even if you are, they should work fine.

I went the other way and use a ten spring flywheel with Barnett spring which are stiffer.  Heavy sidecar and a hopped up motor was too much for the eight spring flywheel.  I’d like a heavy ten spring flywheel but that will take some precise machine shop work.

I said should. I had other clutch issues when I tied them. I changed my clutch set and put the stock 50 year old springs back in. Didn't want to pull it apart again if there was an issue at that time. The old springs work fine considering I went from a 750 to a 1000. If I need to get into my clutch on my Loops, I'll put the wrist relief springs in and see how they do. I think they should do fine.

On a side note. You wouldn't believe how easy a pull the clutch lever has when the friction plates are worn. I think it is because the springs are not as compressed with the worn friction plates. Same cable and levers, new clutch, old springs, hard lever. Whoed of thunk?

When I had my hot rod Mustang I could not hold the 3200lb clutch at a light. More is better, but I also swung a 36oz hammer so I don't have soft hands. My throttle springs don't bother me either.

I too am interested in any other shared information concerning the use of MG Cycles "wrist relief clutch springs".
I've just installed a set in my 1980 SP along with the SD Tech clutch kit. I haven't gotten the transmission back on yet as I'm waiting for a bearing to arrive in the mail.

Once it's all packaged back together I'll return with feedback on my experience. (After an appropriate amount of running.) I'm very interested to hear of anyone who has had some experience with this set up.

Dependant on the tear and model the clutch perches can give more or less leverage.I've put a perch and lever from a Centuro on my t 3 and it seems to be much lighter pull wise now.

  Tom , keep us updated on how that works out . An experience years ago with light throttle springs on my 40 mm Dellortos was reason
enough to stay away from "light" anything . 90 mm big bore kit and cam etc on my Le Mans 2 made the idea of light clutch springs just
an excuse to go into the clutch again , the season in Ottawa was just too short to experiment .  Peter

Moto, I do not have them installed. I tried them when I converted my Ambo to a 1000. Pulled the clutch set including flywheel from my 750, installed the wrist relief springs and used it in the 1000. The clutch set was fine in my 750 with the original springs, but slipped in the 1000. I didn't realize the frictions were as worn as they were. I bought the SD Tech set and used my 750 original springs. Works fine. I do plan to try them again when I have a need to open up one of my Loops.

From your description, it reads like you like spirited rides. If I was you, I would stick with a standard spring set.

MG Cycle also sells clutch springs made by Surflex.  Anyone tried those?  I may need to email Gordon and ask him what they are.  I don’t want to install a non-stock set of springs and find out they don’t work.
