I took the section out last night and is basically a solid piece, the 4 screws holding in place are metric thread m6. It was tight in place and when i went to replace i had to push the front end down slightly to get it back in position, which as you said may have been added to sharpen the steering, May be just a mod by somebody to allow the head or barrel to be taken out whilst in situ.

Sorry here is pic

Hi I am looking for some information on a B40 i have just purchased and about to restore to useable condition. The bike has Bultaco front and rear wheels and forks. It has later GB engine fitted and engine number ties up with what may have been a WD bike. The main question is the top frame rail modification, i guess it was done to allow the barrel and head to be taken off without engine removal but when was it done, picture attached any info appreciated. thanks derek
