Poor MPG...

Right folks...


Think it's about time I assessed the situation of my poor fuel efficiency.


I religiously get between 26mpg (at worst) and 31mpg (best). MCNadvertise my year for 39mpg.


I am still concerned about the pull away being sluggish (even with EXUP fixed). I have no bassis for comparison but I don't feel it is it should be and it's not uncommon for me to hear that metal sound of the clutch plates where usually the revs aren't enough... It doesn't gain it's power to pull away really until about 4k RPM (normal?).


Apart from that, it runs fantastic. The fuel light comes on between 85-99 miles and I get between 100 - 115miles to a tank. MCN advertise closer to the 150mile mark which I have never even got close to. As some of you may know, I have some touring coming up this year so would like to improve my MPG if I can.


My RPM's when riding are typically between the 4-5k mark since that gives me sufficient power and control over braking so I would say I ride it as it should be ridden, not really "conservatively".


Any ideas???


Mileage: 15k (was 9k back in September 14 and MPG has been the same since then).

Actually... just thought of a couple of things...


1) I can hear my front brake grind a bit when maneuvering the bike manually. I guess the brakes are partly applied.

2) I noticed when I was in halfords the other day... a large bee craweled inside my air intake... never came out again lol. I guess the way the R1 air intake is, the air filter can probably get clogged pretty easily.


I have new brakes anyway so can change them this weekend and will take a look at the filter.


Any more ideas welcomed!

Is this just because I destroy you at races?

Take it down a motorway at a steady 80 to 90 and you will probably see that 150 miles


What mcn advertise is the max you get and not real world riding

Where do you think my "at best" figure comes from??? :D


I get 110-115 to a tank with the type of miles you proposed.


Joe - I thought it was normal to the bike but MCN was accurate to my R6 and my mates bandit... and most the other R1's have around the 40mpg figure...

Wrong time of the year to be thinking of fuel economy l think . Cold start systems give the motor the extra fuel it needs to get started and run up to optimum temperature, which on a cold winter day it my never reach. As Stu said a good steady run down the motorway is what's needed to get the best figures. By all means check that everything's in order and that the brakes are free and not binding but l would wait and see what the numbers are after a good run before you get concerned and investigate any further

I'll change the brakes since I want to do that anyway, and check the air filter and as suggested, will wait for the summer.


To be honest though - I'd be surprised if it was due to the cold, September was still quite warm and we had the hottest October in a long time last year and I've never seen any better MPG than I have been getting...


Plus, my R1 revs up to about 2k just for a few seconds then normal idling at about 1.3k. It also warms up really quick, regardless of how cold it's been - around 5mins until operating temp of 73+


It could be just how it is, which would suck if others get 150miles/tank, but there's just something not *quite* right with the pullaway which suggests it could be fuel related.

-----------------------


*EDIT* - I have a ride on Sunday, my mate is coming that has an R1 and had previous models, I'll get him to take it for a spin and let me know about the pullaway.

Standard exhaust minus baffles. Took them out about a month after purchase. That didn't make a difference to fuel.


I accept it could be throttle action... but... that would mean these other R1 owners ride like they just got their licence at 80 years old! I don't think I ride much different to most sports bike riders. Plus, there's not a huge difference between city miles & steady motorway miles... maybe 10-15miles per tank difference.
