Hi Gents,
Thanks for the comments.
I'm not to hung up on originality as there's a Dresda swingarm under my desk waiting to be powder coated and fitted
The speedo shows 20 odd thousand miles (not sure I believe it) but idle is fine with no unusual noises (did the primary chain on the first one I had at 18 with no real knowledge of mechanics but somehow did it!), I'll dig out a photo of my orginal bike and post it (it will be poor quality as it was with a Kodak 126 Instamatic!).
The XS750 is a nice one and very original and now I've rebuilt the carbs and fitted the correct float in one runs nicely - still drinks fuel like a small cruise liner (as did the original). The Honda is the better bike to ride ast he XS handling leaves a lot to be desired
