Scorpa SY/TY 125/175 Four Stroke Setup (2003 to 2007)

First start by fitting 17.5 pilot jet, 102.5 main jet. Set float height to 18mm (turn carb upside down, bottom off, gasket off, measure from base of carb to top of float). Also blow out the 2 small jets in back of carb to make sure that 145 is at the top and the 80 at the bottom as you can get them mixed up and causes it to run sick, the mixture screw should be set at 3 turns out, but this can vary.

Make sure there is ample play on the choke cable when turning handle bars lock to lock to ensure the choke is not coming on.

Removing exhaust baffles; only remove the 2 middle restrictor bars, DO NOT TAKE THEM ALL OUT!

Flywheel modification; standard is 2.1 kg, skim to 1.6/1.7 kg, this will improve performance at the bottom end.
