dan williams Posted July 18, 2018 Author Report Share Posted July 18, 2018 It’s probably time to update the original document with the 24 pages of community learning contained in this thread.

Some of our more talented friends found that removing springs led to clutch slippage so it isn’t a panacea. I had spacers made according to a design by forum member IKB which do something similar without leaving parts out. PM me for details. Do you have those specs for the spacers please Dan :-) I put stainless washers in for now. Edited July 25, 2018 by Eric Brackenbury Quote Link to comment Share on other sites More sharing options...
dan williams Posted July 29, 2018 Author Report Share Posted July 29, 2018 Eric, do you want the measurements or where to get a set. I'm a little confused by the question. Quote Link to comment Share on other sites More sharing options...

Sir Real Ed Posted September 2, 2018 Report Share Posted September 2, 2018 (edited) Great thread! Thanks to Dan and all who contribute. I'm going to take a look at my 2011 Sherco plates. Regarding spacers, without knowing any relevant dimensions, my first thought was shim washers from McMaster-Carr. Precision made, and cheap. McMaster.com. Best search function on any website I have seen https://www.mcmaster.com/#shim-washers/=1ef9nb8 Example: 6mm ID x 12mm OD x 1mm THK stainless steel shim, Part number 98089A377, Quantity 25 for $11.00 Edited September 2, 2018 by Sir Real Ed 1 Quote Link to comment Share on other sites More sharing options...
dan williams Posted September 3, 2018 Author Report Share Posted September 3, 2018 If you’ve got calipers and have the clutch apart grab some measurements. Always room for our Sherco brothers (and sisters) to increase the group knowledge. Quote Link to comment Share on other sites More sharing options...
Beta rev'3 Posted February 16, 2019 Report Share Posted February 16, 2019 I've just done a service a first service on my '19 250 evo so decided to take a look at the clutch...to be fair the plates are very clean. Did anyone ever find some lighter springs with regards to lightening the pull over here in the uk ? Quote Link to comment Share on other sites More sharing options...
dan williams Posted February 16, 2019 Author Report Share Posted February 16, 2019 (edited) Not sure I’d call that clean. Also that’s one of the 3mm thick plates. I take those out and replace with the 2.7mm thick plates on the 2T. What’s that groove in the pads? I’m out of the 3mm spacers I had made so I can’t send any to you.

Beta rev'3 Posted February 16, 2019 Report Share Posted February 16, 2019 Hi Dan no they weren't overly clean on closer inspection, not sure about the groove to be honest I didn't notice it till you pointed it out..I'll put them back in now I've cleaned them up and see what they're like.

Eric Brackenbury Posted March 29, 2019 Report Share Posted March 29, 2019 Hi Dan and the rest of the folks reading this thread. I have finished doing the clutch on my 300 4T factory bike and although the spring pull is fairly firm, the whole movement of the clutch lever is Soooo smooth now. I also did my 390 RR 4T and the improvements to that are amazing. Now I will tell you I have been hand making jewellery for nearly 60 years, what's that got to do with it you ASK ! Well a number of advantages, I have very trained eyes for detail and tools most folks don't even know exist. I removed the excess glue from between the fibre pads with a flat hand carving tool, somewhat like a wide hand engraving cutter. There is no glue as I got it down to the bare metal including the grooves in the tabs. Next I took a cut 4 hand file and cleaned the leading and trailing edges of the tabs with just enough stroke to do the job, then one light stroke to remove the sharp edges. Next I polished them with a fine emery paper (not wet and dry) , All the time I was using my +3 headset and my working glasses. Now you will understand better Why I mentioned what I do. The point is, it pays to get in there visually so you see and understand what exactly you are achieving. I hope my information will help someone to do the best job they can. Thanks so much for your help and .pdf on this subject Dan Quote Link to comment Share on other sites More sharing options...
dan williams Posted March 29, 2019 Author Report Share Posted March 29, 2019 (edited) And I thought I was being precise! Nice work. By any chance did you see the hand made gold TRS piece made for Jordi Tarres by one of his riding buddies? The thing is absolutely beautiful.

totty79 Posted February 2, 2020 Report Share Posted February 2, 2020 (edited) It looks as though several clutch parts are shared with sherco, e.g. updated springs are listed as fitting both. You can get 20% softer springs for a sherco, which might be worth a try. I've gone for the cheaper option and ordered sherco clutch spring retaining washers to try, they're stepped not flat and they are much cheaper than the red top hat ones fitted to some beta's. Edit: the washers aren't a direct fit, they fit the springs but will need drilling out to fit the bolt.
