I set my trip meter and use it as a gas gauge. I just turned 2000 mi on an 03 TW. Just filled it and according to the math it's getting 50mpg. I know something is not right. I do weigh a bit, 270, and when going to town hit the freeway at 60mph if the wind is not blowing into my face. I dropped the rear sprocket a few teeth and low is what 2nd use to be and 5th is like an overdrive. Mostly run 25-45 so what should I look into. I am about 75ft above sealevel.

With stock gearing (14/50) on an 05 and about your weight, I checked my mpg yesterday with mostly highway use this time 55-60mph = 56mpg, which is what I normally get with mostly highway use. When I ride the FS logging roads (15-25 mph), I usually get around 75 mpg, but I ain't been in the woods much this year...yet!

Thank you for the reply. Makes me feel a lot better. I see some talk of 90-100, must be all downhill riding.

I also am averaging around 50mpg and I weigh roughly the same as you do. I'm guessing that this may be the normal for those of our stature

I agree with Admiral and Uwdlk2no2. I weigh about the same and I've always got about the same mileage. I believe "dropping a few teeth" as you say could actually lower your mileage considering the load and engine size. Maybe 1 tooth would increase mileage with your weight. If you were 100 pounds lighter, dropping 2 or 3 teeth would get you better mileage and still have enough power. I went 4 teeth larger (54), I like the lower end but its pretty buzzy at 55mph. Next time I'll put a 53 on instead.

I just fueled up,and at 56 miles it took .80 gal. That = 70, but that is all city,and not going over 45 mph.

Both of my TW's used to get around 55 mpg. Both developed the cylinder base gasket leak so when I took them apart to fix that I installed new rings and lapped the valves in both bikes. Now they both get mid 60's mpg.



I wish I had done a compression test prior to doing the work but I didn't. BTW, one bike is 14t/50t and the other is 14t/55t.

im 165lbs, 14/50, cruise 50mph, rolled up to 65mph a couple times, all road miles, no dirt miles, dirty oil and lower then max spec tire pressure = 90mpg my best so far. i got 70 mpg just ridin up and down street with my son on one tank. i have a 14/47 oring set but not sure i want to put it on now lol !!!

Well, I can finally add something here! I just finished my first tank, and after filling up, my mileage was 76 mpg. My commute to work is 18.5 miles, with a max speed of 45 mph. I have a couple of good long stretches cruising at 35 and 45 mph. I'm 6 ft, 220 lbs!



I'm not twisting the throttle hard either! I know, kinda boring!

 

[jckosnow]

just did the math and I'm at 68mpg. all road miles (this time) top speed 50, but mostly cruising at 40. and I ride like an idiot and wring it out all the time. 5'10.5" 195lbs. stock everything,

 

[plumbstraight]

I guess us heavyweights are just going to enjoy a nice bike that gets from 50-60 mpg. At least I know now that the gas is going through the engine, not through a siphon hose lol.

Blow up your tires



I'ld be like 25 psi if I was 270

Blow up your tires



I'ld be like 25 psi if I was 270



I have gotten between 50 and 80



The tank is very small so minor changes in filling skew the results



Oh try a can of seafoam while your at it

 

[Swamp]

I just filled up today, my second tank full! 79.54 mpg! This last tank was just cruising back and forth to work, again, a steady 35 and 45 mph.
