Thanks for the answers. It’s not leaking. No puddles. It’s not going in the oil either and it’s in the garage. The reason I asked is because if I’m out riding back roads or open dirt roads I’ll get 50 mpg. If the bike sits for several days and I go fill it up my mpg will always figure about 30 mpg. It’s always done this. I’m going to check my vent. It could be venting both ways.

 

The float level on your carb could be too high, gas leaks out the overflow and evaporates. Are you shutting off the fuel shutoff?

 

yes I always run the carb dry. Thanks!
