Hi,
Is the B25 primary cover a straight swap on to a C15? I reckon it is but just want to check before trying to get one.
A definite omission on the C15/B40 not to have plug for checking the primary chain tension and make it easier to do the oil.
Dave.
B25 cover will fit straight on. If either of the two hollow dowels used with the B25 cover are still captive in it you will need to remove them.
