Dave ...are you running the vent to the clean side,
or the dirty side? Running it to the dirty side (outside
the air filter) prolly won't change anything. Running it to the
clean side (inside air filter) will result in a negative crankcase pressure.
Possibly leading to oil consumption, or eventually "sucking a gasket".
I had to route the crankcase vent on some of my stationary engines
when I was on the farm, and yes, they did use more oil.
just hang a small bucket under your scoot.
