I was getting 120 miles before reserve. These days I'm getting 90-100. I do keep my rpms over 6000.

 

how many miles on it? air filter might be dirty.

 

WHEN WAS THE LAST TIME U CHANGED UR OIL ?

 

The bike has under 4000 miles on it. it had it's 600 mile oil change already. I'm waiting till 4000 to change the oil.

 

you should have changed it again at 2000mi

 

I thought it was every 3000 miles..am I wrong?

 

Whats the usual Oil change schedule?

 

Per the owners manual oil isn't due to be changed till 8000 miles and the air filter not untill 12000.
The only variance I see needed is if you don't ride your bike, oil does start to become aidic and can eat away at the engine.
If you don't ride it enough to get the oil dirty sell it. That's just me. I don't do maintence for the sake of doing maintence.
I own a '98 Honda Accord with 200k on it. The oil gets changed every 7500 miles just like they recommend. I trust the engineers at Honda and their recommendations.

What year is your bike? When I bought an 01' last year it had 2100 miles on it. After about a month I lost mpg, took it on a long good ride, got the engine nice and cleaned out.
Now I'm getting 160 miles before the reserve comes on. Your throttle control and use probibly plays the biggest role. I generally keep my rpms under 6k unless I'm on the hiway.

 

i change every 3.5k. it does not matter much anyway.
but take a look into your fuel and air filters.

 

??? I pulled this from the service manual.
