Was looking for some photos in the loft (attic) and found an Alpha 4-1 for a CB750F1, I must have bought it years ago ready to replace the standard system. However looking at it the 4 header pipes appear to be just a push fit into the collecter, is this right, has anyone had one of these systems and can comment on them ? And yes I store all my spare bits in the loft, there is at least 2 CB750F1/F2 tanks and seats up there plus all the various standard bits off the bike that I have replaced over the years, and my BSA spares.
Cheers
Dennis
