bigmark1972 Posted August 28, 2014 Report Share Posted August 28, 2014 I was told it can be helpful to pull 2 opposing springs in the clutch pack so I did that the other day. I also changed the gearbox fluid, it was pretty nasty, I filled it with 450cc of maxima 75 weight gear oil as recommended. I've done a few rides with some folks lately and it was very apparent to me that I need to re-focus on the basics and get my clutch control low speed control down. I spent about 2 hours yesterday riding tight circles in second gear, riding as slow as possible, etc. I was very light on the throttle, not revving it at all trying to balance as much as possible. I really like the feel of the clutch -2 springs but on my ride tonight I noticed the clutch was slipping noticeably. Its bad enough that I can not break the rear tire loose in 3rd gear on the lawn. I was under the impression a person could not wear these clutches out, am I wrong? The clutch was absolutely not slipping at the beginning of that first ride with the springs pulled. I'm a new rider and I won't be using 3rd anytime soon but I do have some trials meets coming up soon. An unfamiliar clutch would probably make things difficult for me I am thinking. Should I replace the clutch or could it just be glazed up from my abusing it? My clutch lever is set up so it engages deep in the travel close to fingers (plenty of room left before the full release) Any opinions, or tricks I am not aware of?

baldilocks Posted August 28, 2014 Report Share Posted August 28, 2014 Did the same Mod on my SWM as the clutch was very heavy, the clutch then started to slip in higher gears. Put the two springs back in would be my advice, its designed to have six springs. What were you trying to achieve ? Quote Link to comment Share on other sites More sharing options...
baldilocks Posted August 28, 2014 Report Share Posted August 28, 2014 Oh and yes you can wear out a Sherco clutch even with six springs. Quote Link to comment Share on other sites More sharing options...
lineaway Posted August 28, 2014 Report Share Posted August 28, 2014 The Sherco clutch was a light pull from the start, put the springs back in. Quote Link to comment Share on other sites More sharing options...
bigmark1972 Posted August 28, 2014 Author Report Share Posted August 28, 2014 (edited) What were you trying to achieve I've been told by several people that this was an effective way to ease the learning curve with clutch control, extend ride times before wrist wears out, etc. I can also point to plenty of posts here where others are saying the same. some conflicting information here it seems. The Sherco clutch was a light pull from the start Really? I'd hate to see what a heavy pull feels like. I can put the springs back and change the oil again this evening but It was NOT slipping at the beginning of my last ride even in the higher gears. It seems to me the clutch was damaged / burnt? during the 2 hours of slow clutchy riding. I would not be surprised if it still slips but will see I guess. Worst case I can put a new clutch in it.

thats_a_five Posted August 28, 2014 Report Share Posted August 28, 2014 Clutches do wear and wear faster as you are slipping them. Your signature says the bike is a 2004. It is entirely possible that the clutch is worn or possibly even replaced by previous owners. But before you just go throw a clutch in: put the 2 springs back in and ride it. If the problem goes away, don't worry about it. at some point you can pull the clutch out and measure the thickness of the stack. I do not know the specification but it should be in the manual. Most of the time when people remove springs it is to lighten the force required by your finger. This does make it much easier to modulate the clutch but it is a trade-off with potential clutch slip in the higher gears. Quote Link to comment Share on other sites More sharing options...
nelly1 Posted August 28, 2014 Report Share Posted August 28, 2014 firstly for riding tight circles and figure 8ts id use first gear and secondly if it has a heavy pull find out why maybe start with renewing the clutch fluid lastly make sure there is some play in the lever Quote Link to comment Share on other sites More sharing options...
rob214 Posted August 28, 2014 Report Share Posted August 28, 2014 also work on turning without using the clutch or brakes, that's the best thing for learning. Quote Link to comment Share on other sites More sharing options...
dadof2 Posted August 28, 2014 Report Share Posted August 28, 2014 Get a had exerciser and strengthen your muscles instead of taking springs out. Trials bike clutches are very light, almost effortless compard to 500cc MX bike or large road bikes. Quote Link to comment Share on other sites More sharing options...
bigmark1972 Posted August 29, 2014 Author Report Share Posted August 29, 2014 (edited) Changed the oil again, put the springs back in and it's good to go Rode for quite some time again tonight and the slipping is totally gone so happy about that. The clutch does actually feel better than it did even with the springs in before, the old fluid looked so bad I wonder if it had ever been changed. Guess my clutch finger better suck it up and get with the program. Edited August 29, 2014 by bigmark1972 1 Quote Link to comment Share on other sites More sharing options...
lineaway Posted August 29, 2014 Report Share Posted August 29, 2014 Everybody used to complain that the early Sherco`s had the lightist clutch. I have tried several times on bikes with very hard clutches to remove the springs. Two things happened. The clutch was easier and the clutch would slip. Usually the clutch would slip at the worst possible moment! Glad to hear it is working again. Quote Link to comment Share on other sites More sharing options...
bigmark1972 Posted August 29, 2014 Author Report Share Posted August 29, 2014 I'm glad too! Appreciate the replies was a little nervous thinking I might miss another meet due to a broken bike. Excited to enter my first event, every time I get the chance to ride with others I get more into the sport. Quote Link to comment Share on other sites More sharing options...
copemech Posted August 29, 2014 Report Share Posted August 29, 2014 Well, good you figured that out! I was gonna tell you the same. I have run the light clutch for a long time and it is trickey at best. On your older bike, I MIGHT be able to do it, but I am half your weight it seems, and even then I would have to go with thin ATF to get a bite as opposed to a slip. It does work fine on my "12 bike though, for my weight. I think they are using heavier springs now. And I am talking it will do a full rev and pop in third for a splatter with no slip. Yet still a delightful light pull for my old finger! Oh well! Quote Link to comment Share on other sites More sharing options...
biffsgasgas Posted September 4, 2014 Report Share Posted September 4, 2014 Full disclosure. I am probably one of the ones that told him it was safe to remove two of the springs. It has always worked with me. Sorry if its caused confusion... MY BAD!!! --Biff Quote Link to comment Share on other sites More sharing options...
bigmark1972 Posted September 6, 2014 Author Report Share Posted September 6, 2014 It's all good Biff, was not going to call you out I've been riding a good bit and the finger is good to go now. Clutch still good to go as well so no harm done. Quote Link to comment Share on other sites More sharing options...
