Honda Spree and Elite 50 Forums

anyone know if you can port the exhaust port on a stock sa50 94+ elite motor? and does anyone know how much? i was just wanting to give it a little more power. i don't want to have to use other gas. and i was going to just smooth down the intake, transfer ports. not really open them up any. anyone know anything about this?

You can raise the exhaust port by about one ring width.

Yea raise it one ring width and widen each side by one ring width. Also clean up the port itself making it a straight shot to the new larger port window you just created. Make sure you chamfer the edges of the port to prevent snagging the ring!
