I have put on the quiet series supertrapp 12 internal disk muffler on my klr650 and have 9 disks in it to lean out my bike a little and I now went from 42 mpg to 40mpg with a minor discrepancy...
I have had slightly larger front tire put on right before the exhaust so the 42mpg is all stock and the 40mpg is with the taller tire and the muffler. I have noticed that top (not tippy top) speed was 99mph stock and is now 88mph so that's 12mph difference so in all actuality I am traveling farther and faster than what my instruments are reading.
so what I'm wondering with all this is what is my true gas mileage? because I am playing with back pressure to economize my engine performance and fuel mileage.

on the 42 I had to switch to reserve at 198 miles on the trip-o-meter and that was moderate to hard miles (heavy on the throttle) it was 4.71 gallons last ride of the season
and on the 40 I had to switch to reserve at 195 miles on the triper but as I mentioned my speedo is off. this was 4.84 gallons and first ride of 04 season

so I know with the 40mpg I had traveled farther than 195 miles.

I rode parallel with a sherpa digital speedo and with mine at 51 the sherpa's was at 57.


so either way 'I' do the math I'm coming up with 45mpg...


what I was looking at was that if my speedo is 11% off then my odometer must be 11% (assuming the instruments are in synch)
so wouldn't the last mileage of 195 be off 11%

at least I'm thinking so...
so then that would be 21.6645 plus the 195 divided by the 4.84
to equal a 44.765mpg
roughly 45 then...
please help me if I'm not right here...

g,
Based on my calculations, you have too much time on your hands.
When the light comes on put more gas in.

i think you need to spend a little more time "getting to know yourself" and a little less crunching numbers you freak... that sounds pretty much right, i think your mileage improved.

sorry about the douche-bag double post guys

LOL... super freak..super freak ay yow!!!... :lol:

I'm getting a gps. Garmin eTrex legend. should be delivered sometime next week. :)


p.s. I'm afraid to get to know myself because then I'd have to learn how to live with myself. :lmao: I leave that up to all you forum goers. :P

i guess we have somewhat different euphemisms here in the NAV. "getting to know yourself" is really more of a bathroom activity....

ohhh shit... I had a glimpse that that's what you meant LOL!!!!!!!
