evo boy Posted November 24, 2020 Report Share Posted November 24, 2020 Good evening wonder if anyone can give me some advice. I have inherited a b40 off my father he took the clutch apart a few years back now. Could anyone please tell me the way the clutch plates go back in ie friction plate, steel plate, friction plate ect? And what oil and capacity should I use in the clutch/primary chain. Many thanks Quote Link to comment Share on other sites More sharing options...
b40rt Posted November 24, 2020 Report Share Posted November 24, 2020 Rupert Ratio book would be worth buying, all the info you will ever need. Quote Link to comment Share on other sites More sharing options...
timdog Posted November 25, 2020 Report Share Posted November 25, 2020 As above, buy copy of the book, separate one for engine, it’s worth it’s weight in engine oil. Explains everything including improvements. Having had problems with clutch slipping on starting from cold I run chaincase dry. The Oil is only for the chain. As bike doesn’t do road work at constant higher revs I just use chain lube on primary chain, sprayed onto it via breather pipe hole. Works for me. 1 Quote Link to comment Share on other sites More sharing options...

b40rt Posted November 25, 2020 Report Share Posted November 25, 2020 ATF works well in primary case, can't remember the quantity but its not much. @timdog I found putting a bit of slack in the clutch cable before first starting when its been sitting makes a huge difference. 2 Quote Link to comment Share on other sites More sharing options...
markparrish Posted November 26, 2020 Report Share Posted November 26, 2020 It's a tiny amount of oil. You fill it up until it dribbles out of one of the studs (removed) - the book will tell you which stud for the cases you have (it's very helpful - as already stated) Quote Link to comment Share on other sites More sharing options...
