Hey. Not sure if this is normal, but for my first two tanks after my 1983 R80RT rebuild, I have averaged 49.6 mpg. Can anyone comment if this is OK?
Thanks!

really bad ... the 1982 R100RT is getting about 34 mpg right now. The R100RT is expected to be the least fuel efficient of all the airhead models but I think that this is still a little too low. I suspect it is because I have about 90k miles and am in need of top end work and now I strongly suspect that my timing chain is stretched. and I accelerate real hard.
R65LS has been getting anywhere from 43 MPG (US) to as high as 50 MPG, depending on how loaded down and how much time I spend with it at 70+ MPH. Usually it is right around 46. Haven't had my R100/7 on the road for long and it is in need of speedometer work, so no data for that at this time.

My R80 ST averages 38 mpg overall. Best I ever got was 47 mpg. Low is 33 mpg on particularly bad SoCal city riding.

Pretty close to my 86 R80RT when I am riding on the Blue Ridge Parkway or other roads where the speed limit is 55 or less. It may vary 3-4 MPG because a slight difference in the fill level can make a big difference due to the small capacity.

Grammarian no, Rider yes
really ??? I am not doubting you, but I have an 85 r80rt and have never gotten over 40+
of course many variables........load, riding style.....riders weight..........city or country.........amount of ethanol.....condition of carb needles

93 K1100RS & 81 R100RS
mileage
1981 R100RS Average 42 MPG. High as 49 when going a long ways at only 60MPH
Holds steady in the low 40's until running nortrh of 90 MPH.
Running hard over 100+ dips to 35-37 MPG.
Only has the 85MPH speedo, but the quartz clock is dead on. Mile markers going bye at 32 seconds on the $.
My 1993 K1100RS gets a solid 42 round town, 44-45 when just cruising around with some free way thrown in. I got 49 on one tank last month riding out to VA to meet some folks.
