maxx2 Posted 2 hours ago Report Share Posted 2 hours ago Hello friends. I’ve become the owner of a wrecked 1987 BETA TR34, which is now running again, although it still needs quite a few things to be fully finished. In any case, it’s already rideable, but I have a problem with the clutch. According to the available parts catalogues, it seems that at some point in the past someone replaced the clutch basket with a 1989 model, because mine is an open-type basket, while the catalogue shows that it should be closed around the perimeter (and based on posts I’ve read here on the forum, the closed one should actually be better than the original type). The problem is that the clutch slips at higher RPM. I would like to ask if anyone has the specifications or measurements of the pressure springs in the clutch basket, and if you could share them. Mine seem visually a bit tired, and after measuring them they’re about 36 mm long — but I haven’t found any information anywhere about what the correct length should be when they are in good condition. The friction plates are in nice shape (around 3.6 mm if I remember correctly) and the steel plates also look OK — around 2 mm thick, not warped or discolored from overheating. Thank you very much for any clarification. Martin Gáborko Quote Link to comment Share on other sites More sharing options...
