The rocker box on the P92 motor that came with the drawings didn't get this up grade , just a standard rocker box .

P92 Rocker Box

The pushrod inspection cover difference you comment on is (dare I say it) pretty obvious.

What isn't obvious is the fact that the inspection cover holes are raised from the standard B50 location ie they are literaly further up from the head/box face.

We've only just started our scrutiny of the drawings but what has struck us is that we're sure we'd see more subtle changes if we had drawings of the standard B50 motor components to compare them with.

We've been wondering where the other P92 parts have got to - anyone like to own up to having anything at all as shown on the these beautiful drawings?

We'll start he ball rolling with a rocker box on one of our Mead & Tomkinson bikes and an outer timing cover with the modified clutch actuation (by welding/machining not from a new foundary pattern).

Pics of both to follow if we can a) find them and b) scan/upload/send them.

Regards to all browsers of the drawings - if you haven't got a cd yet then you should darn well get one and quickly!

Paul (aka beesa71) in the beginning to get sunny UK.
