Honda Spree and Elite 50 Forums

hi all, I recently acquired a few different project bikes. 1 a Honda express 50 1978 frame. 2 a Honda Elite 50 1988 SA50. 3 a 1990 Elite SB50p. I decided to make a funky project and put the 1988 sa50 af05e drivetrain onto my express 50 frame. this is a list of things I did and i was wondering if anyone will know how the setup will perform or possible top speed before i finish. or if anyone has any reasonably priced ideas for improvement. its going for a rat rod look.

stock carb
oil injection delete (premix)
6 gram rollers with stock variator (deleted back cover)
stock clutch and bell
performance cdi
big bore kit installed
polished ports
stock reed
stock drive gears
uni air filer
unrestricted stock exhaust

sounds like express50 has title....... 88 elite sa50 and 90 sb50 has not?..... is express frame for vertical engine?......

They are all documented. I just decided to make something as a summer fun project and take it to biketoberfest here in a few months. The express does not support a verticle engine although if you fabricate a bracket to stretch its length it fits nicely behind the frame.

TAKE a look through this thread^^...trafficjamz put together a couple Express scoots.
The blue Express II is something like what you are wanting...

Wow thats pretty neat! I have no idea anyone would ever do that. Being that i used the 88 SA50 Af05 motor, with the tweaks i posted on my first post, what kind of performance should i expect from this motor with a lighter overall frame ?
