Now that is funny, Andy, and you are right, I wouldn't be having such issues if I had only spooned on a pair of K70's or something, LOL. Fortunately, or unfortunately, the only bike I have with classic tires on it is my DBD34 Clubman, everything else gets modern tires, mostly Avon AM26s and some Bridgestone BT45s.
And thanks MarcB for posting that shot of your 68 Spitfire centerstand, it looks to be the same that I have. Looking at mine closely, mine may have been "reshaped" a little by some prior owner, but it is largely the same piece as yours. As you can see, the centerstand is basically the same as MarcB's
And to pull my left exhaust in as far as Gary E's, I have gone ahead and bought a pair of the same flat and painted brackets 68/2780/1 from Draganfly as you have used. My left 68/2781 is the oem formed piece, and while it clears the chain nicely, it has almost no "z" offset to it, so instead of taking it off and hand fitting it, I will just replace both with a pair from Britain. As you can see, my left 68/2781 is formed, but has almost no offset to it to bring the pipe in.
And thanks for your advice, AllanG, my plan here is to keep all original pipes and such, rather than modifying things with siamesed or up pipes. I think changing the brackets and maybe manipulating the centerstand is all I am willing to do at this point. Thanks everyone for your input.
By the way, guys, your Spitfires are beautiful! Unfortunately, mine is not so pretty in closeup photos, it is more in original fettle with patina complete with paint chips and road dirt.
