SY125/175/200 Setup.
Scorpa SY/TY 125/175/200 four stroke set up -
First start by fitting 10 tooth front sprocket.
Fit 17.5 pilot jet, 102.5
main jet.(standard on later model 200F's)
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 mixted 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.
Clutch for pre 05 models, there is a different hydraulic clucth kit available, it gives the clutch a more progressive feel, this only aplies to the earlier 4-strokes as the new 05's come with an improved Magura system which equaly as good, but these clutch kits will fit on any year 125/175 long ride/racing models.
