So i've kitted my Tomos with a 42mm cylinder and a l style piston. Cylinder and head is also lowered for increased compression.
Porting is currently stock, as is the crankshaft.
Now WOT seems to be okay (spark plug is brownish color) but midrange and bottom end feels a bit rich.
How do i need to tune my slide to achieve a leaner AFR? Bigger angle on the slide ?
