Gas Getting Low?

[BusyWeb]

Hi, everyone.
I'm really curious about MPG and throttling/gearing methods.

Last week, got 100 MPG, believe it or not.
I even couldn't believe it.
It was half freeway (60-65 mph) and half highway (35-50 mph) riding.
Gas was premium octane.
Oil with synthetic.

I want to hear about similar mpg from others, very seriously.
Or, my bike is something wrong??? (need adjustment??)

Is my riding practice bad?? (for my precious bike)
My riding practices are:
(1) No sudden throttling, but keeping smooth up and down when the speed needs to be changed. (sometimes I do rev-up fast at low gears, he he he)
(2) Tried not to use physical braking (both front/back) as much as possible, rater try to use engine braking, for example release throttle and step down gears one by one according to the current bike speed. >> don't know if it's good practice for this small bike. (but need to push front or back brake lightly so behind cars can see the red light)
(3) I change gears very frequently (it's fun, ha ha ha). The 3rd gear is before the 25-30 mph. If it goes up 35-40 mph, it's 4th gear already. If I think that bike can keep 35-40 more than 3 seconds, gear up to 5th gear and keep 5th gear as long as the bike doesn't like it. <<<< these are totally far less speed/gear that GZ manual recommended. But I feel the bike power which can keep these gears at low speed. Am I doing bad???

Anyway, I like my gz's MPG, no less than 70. (less than 1 month riding and measurement) :whistle: :whistle: :whistle:

200 miles per tank seems to be the norm, yes.

Busyweb,
If you really got 100mpgs, I wouldn't change anything.

1) Don't believe it. You had a "measurement error", like not gettting the tank filled properly. Unless, of course, you accidentally got an imported bike and it really is a GZ 125! :biggrin:
2) Using premium gas is a TOTAL waste of money......but it's not a lot of money so if it make you feel good, then go right ahead.

The rest of your story sounds about right......if you want to ride like an old Granny! :crackup

:plus1: to ER's comments, as I've NEVER heard of that type of gas mileage with a GZ. Realistic max mileage figures may approach 80 mpg, but not even close to 100.

Also, read this thread to view all the comments regarding use of premium fuel, it's really not neeeded.

Not ture.

There are reputable members on this site who have seen an actual 95mpg. Under the perfect circumstances, +/- 5mpg from that number wouldn't be impossible.

And maybe not TRUE either!

Guess I wasn't specific enough with my first try at it.
It is unlikely that he is really getting 100 mpg; not impossible, mind you but unlikely enough that it is near-to-impossible.

And, yes, I know one or two people have claimed mileage that high but I think the only one still around it Bob's better half, which IIRC only made it into the low 80's.

So, which "reputable members" claim to consistently get 95 mpg? And that's US gallons, not metric ones.

[jonathan180iq]

I didn't say consistently. Just that they have seen it.

But, Davidc83 is the man and Badbob vouches for him.

OK, that's ONE.......do I hear TWO....... :biggrin:
Guess we'll know after the next fill-up.

I just can't see riding a bike in the manner required to achieve that.
It just seems WRONG somehow.

Hello, everybody.
I swear that my measurement wasn't wrong.
I thought that new windshield may helped some, but it was too much differences between before and after.
I'm waiting for the next gas fill, may be coming weekend.
Since last fill-up, I got about 130 miles on meter.
If I got similar Gallon and MPG, I'll post it with PICTURE proof.
If not, just consider that I had mis-measurement.
However, I'm waiting for next few days.
Um, I'm going to take picture of meter right now.
O.K., I got picture of 09/11/2008 meter.
I'll take pictures of Gas Pump and Meter at next fill-up.
Is it fair?
Hope, I get good MPG.
Thanks.

This has been my experience as well. Of course, I have all of four fill-ups of experience!

On my latest trip, I managed to squeeze an extra .3 of a gallon or so into the top of the tank without spilling over by getting a little friendly with the anti-vapor hose. I still think I have a lot to learn about getting the gas tank full, but not TOO full. I'm doing better though, no spills on two in a row now... Because of the vagaries of filling the tank, I don't understand how anybody can really be sure of mileage on a single tank. I think some riders are charting it over a lengthy period, which should be pretty accurate.

On another, unrelated note, my gas mileage for the second to last tank wasn't too great (ran out at 150), because it included the MSF course. Lots of sitting around doing nothing. This tank included a 72 mile run too Corona Motorsports and I ran out at 180.

I think it kind of sucks that I can go about 550 miles between gas stations in my Suburban (thing uses a gallon just to get up the driveway) and only 180 on Suzy Sipper. I'll get over it.
