Most opt for the 836cc kit.  There is an kit for less than $150 (sold by cruzin - something), that had received positive reviews.

Need to choose a good cam, too!  I recall a DP295 was a recommend choice.

A post from Hondaman on this topic - page 2, middle:

Also good info from jweeks.

CycleX has a drop in nice 915 kit but most also upgrade rods when going over 836. Just depends on how else you build it out for more HP and how you flog your dog.

No, that's the nice thing about the auto, the frame is made in a way that allows the cylinder to be removed without pulling the engine.
