Hello I have a question. I was just wondering if anyone has any idea
if going with a larger tire size in rear would give me better gas
mileage. I have a unique commute where 17 of my 18 miles is Interstate
81 (67-77 mph), and I have a total of 2 stop signs each way. If I
could drop my RPM's by say
Unfortunately, I don't think you will be able to fit a big enough tire back
there to see 3-5 mpg increase.
3-400 engine rpm might net you one point improvement; that's about what the
bigger rear on my 750 bought me

Engine RPM alone does not determine MPG. Energy demands do. Assuming your
speed does not change, it will require a certain output of energy to propel you
down the road for a given distance. Would a lower rpm increase MPG? Perhaps,
but not much. You will need to maintain a certain amount of
thats one way to think about it
fun and low MPG or boring and somewhat better mpg

If you aren't totally addicted to speed but are a competitive person by
nature, driving for MPG can actually be just as exciting as going fast. You
have to be creative, aware, and totally in tune with your vehicle and the
world around you, but beating your previous best is a very satisfying
wow 49mpg, thats something
i got to try to achive that on my 750

Mike,
I will look into different sprocket instead of a different tire size. I am
not totally sure a different sprocket will increase your mpg, but you do
cruise at lower rpms if you choose the right one.

On Thu,
Last year on my 82 750 I changed the rear sprocket from 43 to 40 teeth. I
stayed the stock number on the front. I also changed the chain. but it went
from 6000 rpm to 5100 rpm at 70 mph. giving me about 8 more mpg.

Try tightening the head cover bolts first. My 750 was leaking and I solved
it doing that. I might need to replace the gasket eventually, but I think
they cost around $50-$70.

What's the voltage across the terminals? If you have enough juice for the
rears, you should have plenty for the fronts. Check your connections before
replacing parts.

That's a massive improvement for a small change (relatively) in rpm. Any
other changes at the same time? Filter, plugs, tune-up, driving habits?
That's claiming 20+% mileage increase off a 15% decrease in rpm. Highly rare
situation, unless you're moving from a fringe to an optimized engine
I did brakes, along with the sprockets and chain, oil change. no tune-up or
anything else. went from 42 mpg too 50 mpg. like I said, it decreased my rpm
900 at 70 mph.

Still 19% improvement for a 15% reduction in engine speed.
Perhaps you had a slight drag on one brake that changing them cured to help.
Not denying your increase, but the usual increase is a slightly lesser
percent than the rpm drop. Just trying to explain this one.

maybe the engine just runs more effeciently at 5100 than at 6000 rpm.

Same leak happened on my bike, at about the 50K mile mark, and it gets
worse if you ignore it. It's a common problem with the NH750, The fix
is a new valve cover gasket, and don't forget to get the little seals
that go with it.

According to the *original log book* the gap is 0.8 - 0.9mm (0.03 - 0.04in)
And I'm only guessing that would be for the original plugs - an area I am
currently researching. EG - I am learning that an iridium core plug will
jump a larger gap due to lower resistance - wont go on till I know
If you want better mileage, go buy a scooter. Sheesh!

Just read through the other responses...
Your most realistic bet is to drive 60 to 65 mph and leave home earlier. As
with cars, MPG at slow speeds is mostly dictated by weight, and at high speeds
it's all aerodynamics.
I can prove to anyone that wants to ride in a car using my engine scanner

Didnt mean any offense with the scooter thing, just my own line of

get better mileage, but I ultimately concluded that for me.. it misses
the point of motorcycles. It's all about having fun, and I like the
fact that its as quick
To check the stator: test for continuity between all 3 leads, also look for
similar resistance, lastly check that you don't have continuity to ground. If
it fails any of these tests it is bad. To test the R/R hook up a volt meter to
the battery and see if it is charging while running after
One tooth on a front sprocket is the same as r teeth on the rear sprocket. So
that is the same as a 16 tooth countershaft (front) sprocket.
