  1. Started by Tomsmokes93,

    Hello! We have recently had a family member pass away, who had an old BSA in the corner of the garage. I'm trying to find more information about it as I don't really know a great deal about BSA and whether to restore it. I'll attach photos. I can't seem to see much info about the engine either to figure out what year it is. The number on the engine itself is C15T 179? Any help would be greatly appreciated!

    Can anyone help me to identify these forks which are from a B40 trials bike I got earlier in the year (Surrey area). I've stripped them to replace the seals which were shot but cannot find anything to suggest a manufacturer. Stanchions are 32mm diam and 597mm long (parallel along entire length) There were two 42mm x 32mm x 7mm seals in each fork (is it normal to have 2 seals?) I'd like to get info on what volume and sort of oil to use in them Thanks in advance for any replies.

    Hi, does anyone have details of the construction of the 1950's Canterbury trials sidecar bodies. I have a chassis and want to build a body. I have quite a few pictures of the outside, clearly aluminium, but don't know if there is a ply or ash frame and floor. I would be grateful for any information, dimensions would be great. Thanks

  7. Started by jamestee,

    Looking to pick the brains of 2 stroke guru's. Have a Villiers 250 fitted with a Marcel barrel (trials) and am having carb problems. The engine seems to run rich, and to get a 'normal' plug reading, and no oil in the exhaust, it needs a 100/110 main jet. With that fitted, the needle in the top ring, and a No4 slide fitted the engine runs ok at all settings above 1/8th open, ie just a little rich looking at the plug (GKN BP5ES) and 2 stroking as it should. Now the difficult bit! With a 25 idle jet I can get it to tick-over, but at low throttle openings, ie less than1'8th, the engine 4 strokes. If I open out the air screw to where it will 2 stroke, it will not tick over, ex…

  13. Started by old trials fanatic,

    Changes for 2016 at Peak Classic To try to increase the numbers of bigger bikes taking part in the Club Championship and also to try to cater for machines that seem to have been forgotten and the owners of which feel that rightly or wrongly they are at a disadvantage when riding against some of the more highly modified British Bikes around nowadays. We therefore decided to introduce the following changes for the 2016 season. We will along with bonus points for British bikes over 351 cc be introducing a class for bikes from the late 60’s and early 70’s that have been languishing in sheds and the only time they have seen the light of day recently is at shows. So dig …

    Hi, anyone know how to contact Charlie Harris if indeed he's still around? I'm trying to piece together any history of my Montesa Cota 330 which I'm quite sure used to be his and supplied/supported by Robinsons of Rochdale. I think he was originally from up north somewhere or possibly Midlands? and spent sometime in the Weymouth area which is how the bike ended up in this area. I bought it from someone he sold it to who worked with him at Bovington or Lulworth camps. I seem to think he may have moved east from Dorset possibly Brighton way, but I did see mention on his name (Possibly Same person) on the Redhill and Reigate clubs results from a few years back, riding …
