Very logical, no problem, easily done except that I dropped the box with assorted grommets. Took some time sorting a hundred grommets again. Some earlier owner had threaded the gusset hole to M8. Naturally it was cracked and welded and cracked again. Have worse problems than that. Oil tank leaking on at least three different places. Looking at the other 40M thread, same oil tank as mine. Guess I'll have to send a mail to Ken Macintosh. Funny thing about oil tanks, according to the previous racer, it had the oil tank in the fairing, never heard about that.
