What's the final drive ratio on your bike, 3.89 ?
 

Yes its 3.89

I would think the RS fairing helped.  I sometimes feel like a flat plate at high speed and that's with the low Euro bars.

Filled up the fuel tank this morning, first time since installing the 138 jets .

5.3 gallons US, 227 miles .

Works out to be about 42.8 miles per gallon .

Looks like I may have gotten a bit better fuel consumption with the smaller main jets .

But this is only one tank, to be continued...............

Bob,

Any noticeable change in general performance, acceleration, responsiveness with the smaller jets?
