hi
i dont know if any of you can shed some light on my question?at the weekend we replaced the primary drive chain and damper rubbers on my friends 1978 jota.we had the new triplex chain and rubbers and rivets supplied by slaters.when looking at the job i noticed that the rubbers were not riveted in as expected but held with bolts.you could see light scoring where the original rivets had been ground off.the keeper plate was not bolted through but the holes that the original rivets passed through had been tapped m6 and some m6x20mm bolts used to hold it all in place.now this is the thing,he has owned this bike from new,he knows the full history of every thing done to the bike and the rubbers had never been changed before for definite,so had this been done at the factory for some reason,because i thought the bolted clutch chain wheel assemblies were later.as maybe my rgs would possibly have.
