Thank you, all!
Yes, the 550 is currently modded a bit, but I made sure to get all of the original parts the seller had as part of the purchase, which include the fender, lights and some brackets. The aftermarket exhaust isn't my favorite, but I'm sure with that if I'm patient, the right deal on a stock setup will turn up. I hadn't considered the front tire, but you're all right, it needs to go. Could I trouble any of you for some guidance on the replacement?
The 750 is an 18k mile barn find restoration that has been sitting since 1983. The safety/mechanical/electrical components are all either new or refurbished, but what makes the bike really special to me is that everything cosmetic is original; super clean, yet complete with years of blemishes and patina that make her truly beautiful.
Cheers,
Andy
