Over the last seven days fitted a new yoshi r77 slip on, power commander, K&N filter and put the relavent map on from the dynojet website... I was concerned abt the mpg i was gonna get with the new setup.. So i had a run out to Cadwell park to spectate Yesterday to see what the figures would be? The bike runs super smooth and is as quick as I expected.. I took my other half on the back so more weight with the pillion and rode steady to fast pace with the odd full throttle open up on a couple of times open roads... From full tank to fuel light coming on i achieved 140 miles... I was very happy with this and so not worried anymore about the fuel economy of having performance parts fitted...
i can get around 50mpg and thats sticking at 70-80mph if im ridding nice and smooth or so the computer says anyway
when i got my RR5 - no PC just a full race exhaust..i got 140 miles to the tank..riding on the motorway at 80mph! though very boring! i did it...! from that day on i get between 90miles to 100 miles commuting to work and back.. 20 mile daily trip.
