TERRIBLE MILEAGE

My bike has a Hindle Full Exhaust system and PC3.

The bike was mapped to the Hindle Full Exhaust map file when i bought it.

I noticed the bike only gets 20MPG like that. SO i tried two things. I send over a ZEROED out map. And Also sent over the Stock map. Running both these maps the bike STILL only gets 20mpg. Im super confused and am not sure what to do.

Forgot to add, its a 2001 929RR

What bike is it?
Does your crankcase oil smell of fuel?
Have you checked the fuel pressure regulator?

I can't smell so I don't know how strong the fuel smell would be.
Pull the vacuum line off the fuel pressure regulator and turn the ignition on to pressurise the fuel rail. If fuel comes through then you need a new regulator.

Thanks for the reply, i tried to search up how to find the vaccum line/fuel pressure regulator but came up with nothing. Is there a diagram or manual or such that you know of?

Re: TERRIBLE MILEAGE

I know it wont help a tremendous amount, but when was the last time if ever the axle bearings were changed? I changed the front bearings on my 929 and the front end feels like a new girlfriend, have not rode it long enough to see what I get out of the tank, but as free as it spins now it should be a decent bit.
