I usually average about 49 mpg. Lately it has dropped to about 46 mpg. Today I filled up and only got 40.9 mpg. I ride the same way I always have and can't figure out whats going on. I read in a bike mag. the other day of somebody's mpg dropping off and he change his spark plugs and it fixed his problem. I changed my plugs today. I will have to wait to see if it helped. If anybody has an Idea of whats going on I would love to hear it.
