fuel consumption
 

Hi! I don't know if this topic has been covered already in these forums, I just want to ask what mpg you guys get from your hawks? I have a hawk with stock carbs and stock pipes (but has has 8holes drilled on the baffle walls) and I get about 12-13 kilometers for a liter of fuel. What do you guys get, on the average, from your hawks?

The search works some times . :cool:

Thanks!!

reading that tread about mpg i noticed that there is a number of gas reanges. I guess that im in the middle more or less. I can go :evil: 90-145 :cool: miles on a tank. all just depends on how and where im riding...good luck

mileage
 

I just got a New To Me Superhawk two or three weeks ago.

I got 17 mpg on the first tank, plinking around locally. The next two I got 32 mpg and 37 mpg respectively.

I spoke to a local guy with a newer Hawk and he said he "always gets 36 or 37 MPG"

HTH

Yeah i get around 96 befor the light comes on

I hit 120 miles before the light comes on. This is under normal driving, with a occasional acceleration spurt (Going from 1-4th, shifting around 8k or so)

It all depends on how you twist the throttle. I've gotten 45 mpg during easy highway cruising, and as low as 28 mpg hard riding. About the same as all the other Honda sportbikes I've owned. Only real difference is the 'Hawk uses a smaller tank.

Seeing all your gas mileage with the hawk, it really averages to only about 30-35mpg. I was quite used to the bike before I got the hawk, it's a '96 fireblade, where I got an average of 42-44mpg. :|

and your gearing, and your weight

I normally run the twisties in the 4-5500 rpm range. Twisties is all I ride. I'll do a few hard acceleration blasts up to 100 or so on a tank. I've never seen lower than 38 mpg, and I normally see 42 mpg. I typically get 135-145 miles before the light pops on.

TBR full system, jetted (a bit rich), otherwise stock, and I'm a fatass at 6'3" and 300 pounds

I get a pretty consistent 43 mpg with a pretty much stock carb (just shimmed needles) and exhaust. Mods, jetting, riding habits, etc all affect gas mileage. Even on the lower end that some have mentioned its still better than my Chevy Avalanche Z71 or my '66 Chevy Stepside pickup It would be great to get 75+ like my Suzuki DR dual sport gets! :D

RickB,
Can you tell me about the shimmed needles? Is there a thread on this by chance?

you should be able to do a search for more but here is the thread that I replied to:

https://www.superhawkforum.com/forum...ead.php?t=3437

basically it lets the needles sit a bit higher in the jets to richen up the mixture a bit. You may want to check out Greg's site for more info as well - should be in this thread as well. it seemed to make mine run smoother at low throttle.

Basically, I think that the VTR part throttle timing curve is far from optimal, I would be curious to map the TPS/RPM to get a better picture of the engine operating conditions. I will try to find a way to do this since I could use this as a base map for the Microsquirt conversion. Another snag is the big overlap and decreased exhaust backpressure that loose some of the charge trough the exhaust. I'll make some testing on restriction/consumption during the summer and I'll post the results.

As another side note: Your range will depend on how you fill your tank? My gas light has come on at around 95 miles, and feel nervous if I don't fill it by 115 miles. How far can you typically go with the gas light on? What is the total capacity of the fuel tank?

I fill the tank just to that metal strip that you can see in the fuel hole.

Lol, I'm nuts, I shake the bike to get more bubbles out and thought of drilling an bleed hole to get even more gas in there, if not used right away when it expand it would pour off the drain hose. Just another symptom that it's waaay too small

K&N, Stage I jet, Erion pipes - get about 120 to a tank hiway - 100 twistys

I wish the tank had .5 gal more space, but it means I have to stop to pee & drink another beer (j/k) aqua

First ride of the season yesterday and at the 130 mile mark my RLOD still hadn't illuminated. Pulled into the Shell and squeezed in 3.38 gallons to replace the Sta-bil-ized 3 month old fuel I'd burned up. That's with me straddling the bike and holding vertical as opposed to on the sidestand. About 38.5 mpg with Yosh RS-3's (race baffles) and FactoryPro jet kit (stock pilots and mains).

When I get about 100 miles on the odometer I start looking for a gas station

Since I got my faulty fuel sensor replaced last month, here is my data:

N1-3.17 gallons, 90 miles, 28.4 mpg
N2-3.0 gallons, 87 miles, 29 mpg
N3-1.37 gallons, 53.7 miles, 39.2 mpg (no RLOD)
N4-1.55 gallons, 52.8 miles, 34.1 mpg (no RLOD)
N5-2.6 gallons, 87.6 miles, 33.7 mpg (no RLOD)
N6-3.4 gallons, 96.8 miles, 28.5 mpg
N7-3.3 gallons, 110 miles, 33.3 mpg
N8-3.1 gallons, 85 miles, 27.4 mpg

total miles 662.9, total gallons 21.5, avg mpg 30.1
tank total capacity 4.2 gallons, total usable 3.5 gallons

Half of this is commuting, half of this is twisties. Stock jetting, Jardine hi mounts, 35K miles. All fuel is filled while straddling the bike. Compared to most people, my mileage is pretty sucky. If anyone has any advice on how to improve this, I'm all ears.

(edit: this is at sea level with 43T chainring)
