Titel: 1958 R26 Valve head sizes
Beitrag von: bwprice100 am 11 Juli 2016, 13:54:29
.
Just a quick question chaps with regard to the valve head sizes on my 1958 R26

In my copy of the manual it states a valve head size of:

32 mm for the intake
34 mm for the exhaust

Surely the intake valve should have the bigger head?

Thanks Brian

For R26: 34 mm in and 32 mm out.

Sure, that your manual ist the right one?
It taste a littel bit funny.

Thanks for that, I couldn't believe it was correct and on page 57 of my manual there is a drawing that shows the correct sizes.

My PDF copy does, however look like a scan of the original???
