Clutch Set up Clive Worrall and Paul Compton.
Most important to set your pressure plate up accurately.
The three adjusting pins on the pressure plate must have half to three quarters of a turn clearance when the clutch is in but the plate must run true when it starts to lift, if not it will grab and snatch as you pull away and slip when it gets hot.
To achieve this it is necessary to play around a little because if you wind the screws in until they touch the lifting bearing then back off half a turn(ish) the plate will more than likely lift out of true when you pull in the clutch and turn the gearbox over. So a little messing around here is required.
Unlike the Triumph arrangement as the friction plates on the Silk ware the three pins will eventually contact the lifting bearing and the clutch will start to slip. If you have new plates in as a guess the pins would need resetting at about 5-6,000 miles.

Hello Mr. Worrall,
I hope that this is the correct way to ask you for the availability of Silk parts and that I don't bother you. I am the owner of Silk No. 112/114 and am especially interested in the clutch improvement you wrote at Roger Moss's site. I would be pleased for any information and thank you in advance Hi Dirk, Nice to hear from another Silk owner, How long have you had the bike and who owned it before you? Just a quick bit about me. I worked at Silk Engineering from 17years of age 1975 until it closed in 1998. I worked mainly in the machine shop but took over the servicing and spares when Silks stopped making the bike in 1980. I thought it was right that some kind of spares and information service should continue, but I am not a business. I am afraid it is mostly information that I have these days. I just try to help out where I can and make some money to spend on my motorcycle projects. I have started putting information on the www.silk-motorcycles.com web site that a fellow owner is managing. Please add anything you feel is interesting to the site. The clutch plate mod is as it says in Rogers page. I can supply a new plain plate £10 plus post or I can get the Triumph set of plates plus post to me for you and put a small mark up for my trouble and post them on to you or you can get them yourself from Wilemans Motors Siddals Road Derby Tel 01332 342813, they do a very good mail order service and save a bit of money. I shall post this information on the site also as it saves time repeating stuff. I shall wait to hear from you. If you can send a picture of your bike to me I would be very pleased to add it to my collection and one day send them all onto the web site. |
