how do ya check piston wash to see if your too lean or rich? do ya run full open then kill it at 100 mph then chek? or do ya do one at 1/4 throttle then 1/2 then full?? or just ride normal for 2 miles?
A couple of shortish full throttle pulls first..................check with a light, if ok move onto a couple of long pulls. I also checked mine at mid range / cruising. Once I got a base line I monitor it with EGT gauges.
