Something isn't right. I get 30 mpg with my 124" bike with the sidecar attached. I miss getting 47 mpg on two wheels with my old 98" setup.

Sounds like it's running rich. Pull your plugs and see if they're burning black. If so, take it back to the dealer. maybe they put the wrong update in.

That's one of the reason I leave an engine stock. It usually does take long to diagnose a problem.
