i had the kit on my very first zed650 and would recomend keeping an eye out for some lumpy cams to get the full benifit of the big bore, although you could just fit 750unitrak cams to try for a start...if i remember rightly the only other mod on the motor were some z900/1000 carbs.... it went like stink around the red line 8-)
My B1 runs a Wiseco 720cc kit. Petrified of it going bang as no spares available afaik for 720cc kits. Goes really well and Alf in Worthing owes me a dyno run to see the figures. It's also had some dynojet carb kit installed, but 20 years ago! I'm just glad that she runs sweet after replacing the primary chain. I'll post a pic in the new members section.

An 810 would definitely wake the motor up. How you ride and what you want to spend would be the deciding factor on how to build it and where it makes power. Do you want to have tons of torque for around town riding stoplight/stoplight,or are you interested in making power higher up the rpm range?
