ok soo my bike is running at least 6 rpms on the freeway thats in 6th cruising at 70.. lowest i can get it.. the bike is swallowiing the gas likes its beer at nascar.. idk what to do.. ive been staying on the streets cause other whys im putting gas in her all the time.. and its not economical at all... granted i need new jets but i still dont think they would be this big of an issue would they?.. feed back please...

 

Smaller in the back bigger in front

 

What is your current gearing - look at the charts below, to figure out what your RPM should be at in 6th - I made one for stock 15x43, the common 14x45 (-1,+2) setup, and 15x45 (-0,+2).

For all 3 though - 6000rpm in 6th is going to have you within +/- 5mph of 70, so you're sounding right as far the RPM the engine is turning - now how much gas it is drinking is the next question.

 

If you want lower rpms go to Gearing Commander, load your bike's stock gearing from the drop-down menu and experiment with what different size front or rear sprockets will do for you. Just like on a bicycle, bigger front means lower rpm at the same speed and slower acceleration/harder to wheelie. Bigger in the rear means higher rpm and quicker acceleration.

You said that it drinks fuel like beer at a NASCAR event. Did you do an actual mpg calculation and, if so, what is it? If you're an aggressive rider something like 35 mpg wouldn't be too unusual.

+1 - Gearing Commander is where I grabbed those screenshots.

 

i ran -1 front and -1 rear still feels way better than stock but cut down on the high way rpm's just enuff since i ride high way 85 % of the time. and i get about 42mpg's and it see's redline just about each time its out

 

yea its not evn getting that on the 35 miles i dont think.. im doing one right now.. ive been trying to but somehow forget to.. but im sticking to this one so i know for sure.. an ok cool thanks guys.. just needed to know if it would make a difference..

 

Last time I did nothing but high way miles I got 60mpg doing an average of 55mph on +1/-1 gearing. 6k RPMs for high way driving is fine if you are doing 65-75mph. Do you have close to stock gearing or was your bike set up for stunting? (huge rear sprocket)

Gearing helps gas mileage a little bit, but honestly, 99% of it comes from proper jetting and not opening the throttle very wide.

35mpg is pretty standard if you are stop/go riding, opening the throttle and having some fun.

 

i just did mine an i was geting 160 on a tank but thats inbetween 4k an 5k cruising in 5th at 50-55
freeway i tried to stay inbetween 6k an 7k cruising at about 75.. um my bike is all stock.. well till i replaced some things but yea i just got the new sprockets and put them on the other day so everything is good now.. but i havent noticed any change yet.. but i did just fill up so maybe we will see improvement... still gotta get better jets.. im going for K&N or dyno.. any you think would be the best?

 

So our bike stock is 15/43 right? If so, where do you guys get your chains and sprockets? I know I need a new chain so i was considering going +1/-1 or +2/-1 after playing around with Gearing Commander (thanks adrenaln and Roadijeff). not sure yet. But on bikebandit all i see is 14/43's. Thanks
