I took the tach drive apart on the Aermacchi since the tach wasn't working when I test rode it. Half of the problem was that there was no grease, that problem is solved
The other half, and main problem, is that the tach cable's end that connects into the drive is sheared off. Simple fix.
Wondering if I should lose the dash pod and get a nice Veglia race tach and just run that. This 250 is so slow I think I'd rather just know the rpms and listen to the engine, thinking I'm on at Bonneville. Despite considering all this I took apart the stock dash panel, cleaned up the instruments, cables, and wires, and then implanted all of them into a nicer '68 panel which I'm digging. The stock '67 was just plain aluminum and mine was cracked, chipped, and beat to death. The '68 is a little bigger and better designed, still aluminum but with metal hammered black paint on the top, and has an all important SS sticker. Same P/N and everything went in nicely.
Speaking of stickers
