hey, glad you like it! the engines are on the weaker side on purpose, realistically you wouldn't get a ton of power from a carbed OHV 1 liter 300hp is about the limit of what I think you can push outta the biggest one, and that's still enough to break traction in 3rd gear the mid-engine body is also like that on purpose as it's meant to be a one-off (or I guess two-off) type of race-oriented build, so all unnecessary stuff got thrown out (tho the standard dashboards & seats are still available, I assume your'e talking about the interior carpets?) that's roughly the same as a standard production Hayabusa, pretty sure you can do a 0-100kph in 1st gear on that bike I could try adding an adjustable final drive, tho you'd have to imagine the correct number of teeth on the sprockets yourself originally I wanted it to have both a locking diff and a rangebox, but for reason that I don't actually remember now (I think it was lack of space or something) I decided on just a rangebox, and instead of the locking diff it just got a shorter final drive (which still is more than what you'd get in a 147 Rustica) I guess you can chalk it up to the Italians doing things their own different way
