Mééééé, ..si jeune Mabuse, ce ne serait pas ces mêmes embrayoires qui se montent avec peu de modifJivaro a écrit :BTH TT. Une excellente magnéto racing. Zerton, tu me sembles avoir des connaissances étranges, pour identifier cet embrayage ainsi. Faites gaffe, les gars, c'est peut être bien un espion.
Et oui ça ressemble aux lifters de Harley (j'avais changé les rouleaux des poussoirs de l'harley wlc que j'ai restaurée) mais sur ceux de la BSA il y a des ressorts de rappel interne.marinatlas a écrit :Bonsoir Vincent, j'ai trouvé çà pour tes poussoirs à rouleaux....amicalement Pierre.
C.R. Axtell and his partner Mike Libby developed a roller lifter conversion for the Commando, but never marketed it. They used roller lifters that had been designed some time back by one of the SoCal aftermarket cam companies, but I don't recall which. The lifters had been designed for the BSA Gold Star, and Axtell had a box of them left over from the flat track bikes they raced. After Axtell retired (and eventually passed away) Mike continued with the development. He used a bronze insert in the lifter tunnels, much like the BSA radiused lifter conversion, but machined to act as a guide to keep the roller straight. As far as I know, he never ran one in a Norton, but did do a similar conversion for a local Triumph vintage flat track racer, and it worked great. Mike was looking at producing them for both brands, had made the tooling to drill the Norton cylinders for the lifter block retaining screws, and got some bids on making the parts from a local speed equipment job shop, but got stalled by the need to work on paying jobs. I haven't talked to Mike for a couple years, but as far as I know, he never went any further with the project. The lifters looked a bit like the Nourish Westlake ones posted above. The cams were Axtell designs with the lobe shape modified to provide their normal lift profile with the roller lifters.
