Looking for project number two since the wife has laid claim to the 400........my question for everyone would you get another 400 or go bigger ? The 650 was on my short list when I found the 400 so thinking.....also found a XS750 local and the three cylinders kind of intrigue me in a weird way.....want to stick with an XS so let me know what you think.....I also have a lead on a 82 400 with a mono shock and DOHC motor.......
