while the bottom end is away Ive been looking at the top end of our B40 (1965 US import)
head is a 41-211 6stud big valve type.
Ive re lapped the valves but am looking at replacing but having trouble identifying from Wassells catalogue.
Exhaust at 1.409" head dia, .309 stem dia and 3.465 length. is a V212 so presumably B44
Inlet 1.541 head dia, .3095 stem dia and 3.506 length cant find an option? any ideas
Inlet springs are double , outer is 1.687 long and inner 1.530 long
Exhaust is 1.677 long
can this be confirmed only one spring on the exhaust
been reading through Ruperts book, the pictures shown have slots in the rocker shafts, to help line up and set clearances, ours dont have slots any difficulty without?
Below from an old Alpha catalogue gives the valves V numbers but no dimesions.
Draganfly list the inlet 41 24.
Exhaust valve also has inner and outer springs. The SS engine used the same springs as Gold Star
thanks Julian, V223 (41-24) seems the best compared to my sizes and GS Valves site http://www.gsvalves.co.uk/assets/vintage-motor-cycle-catalogue.pdf
dimensions at back of catalogue.
Thanks that is a useful catalogue.
thanks back to you Julian, I searched the V numbers on your sheet and its one of the resuts I got. ;D
