16 Tooth Front Sprocket vs. MPG?

gossterd · 06-08-2007, 01:54 PM

Has anybody noted the effect on gas mileage after changing the front sprocket to 16T?

Thanks, Tom

I would guess that it would be better with the 16-tooth sprocket, being that you get better cruising speeds and don't have to rev the engine as high.

Most of my travel is around town anyway, and I haven't noticed any change at all in the MPG. However, I expect it to be a bit better out on the road with fewer stops.

I've seen increased mileage on my last two tanks of gas, each higher than the previous.

I never averaged higher than 65 MPG before the sprocket change.
Since the sprocket change I've achieved 68 and 71 MPG respectively.

I'm charting this and I'll release the results once I have enough samples.

Take care,
Jonathan

I got 86 & 82MPG out of my first 2 tanks, before changing the sprocket.

I installed the 16T sprocket last night, so I'll post the results on my next fill up.

Are you sure you calculated your mileage correctly? Those numbers are way on the high side of this bike..
Care to share your method?

I know my MPG is way high.

Calculation is very simple... miles on the tank/gallons to refill the tank

My commute to work ( about all I ride the bike ) is 17 miles one way.
The first 3 miles is slow city driving at 30MPH, then I have a long 10 mile stretch at 40MPH, and a 2 mile climb out of the valley at 30MPH, and finally a 40MPH straight 2 mile run to the parking lot. Not much stop and go. I shift the bike early and take it easy.

I realy like the new 16T front sprocket!! On the long 40MPH stretches the engine isn't turning as many RPM's which has got to help gas mileage :-)

I'll repost when I buy gas, which by the way is around $2.75 a gallon here in Ohio.

Regards, Tom

That's pretty good stuff. Congrats on your mileage. I only questioned your method out of jealousy, as I can't even come close to 80. 86 is phenominal :drool:

As I have stated before, I get 70+ mpg each time I ride. Example, yesterday I filled her up (put as much fuel in as I could without overflowing so I wouldnt undercalculate) and I got 160 miles on 2.2 gallon, which is close to 73 mpg and most of this was Interstate driveing between 65-70 mph.

While I was in the Smokie Mountains, I constantly average between 95-100 mpg doing around 40mph for the 4 day vacation while I was there. Just easy on/off the throttle.

Just checked my mileage since changing to a 16T sprocket.

I got 85 MPG. No change that I can see. I'll post again after this tank.
