It does make lean for me on light ported Puch polini 4 pedal 21mm phbg that has high 101jet (comes with 92 jet, 262 atomizer) and rich 264 atomizer and rich needle setting and a puch polini 19 mm phbg with rich 96 jet and needle setting but other bikes that I run closer to stock jet/parts

I had no lean problems so some bikes I run them some I don’t, washer is more needed for bumpy and off-road use,

One bike I have to run anti-surge washer and spring loaded float needle to stop surging (Spring loaded float needle is pretty cool too it helped surging and stopped staling on fast/emergency stops on a problematic bike)

Float height is so important, on some bikes/some carbs you need to have so high that it almost leaks ,
