fuel consumption

three3third · 07-15-2009, 3:36 PM

Hi everyone
I ran out of gas this morning on my way to work and I had to stop and switched it to the reserve tank. The thing is I filled it up last week and the full tank seems to only last me for 195km. is it normal?? if it's not, what would've gone wrong? I shift gears at 5~7000 rpm so it's not like I'm a aggressive rider or anything. a litte help please.........

I usually fill up after every 190km or so, and thats usually after a mix of gentle cruising and thrashing it a little, but have never let the bike run completely dry though. I remember reading an article on these bikes and it mentioned poor fuel consumption.

Thank you for the reply Kid-Dynamite.

so if that's the case, maybe there's nothing wrong w/ my bike then. Thanks again....

Mines about the same so I shouldn't worry about it....

Surffrog · 07-16-2009, 3:32 AM

Mine too. Wouldn't worry about those figures

three3third · 07-16-2009, 4:02 AM

thank you guys and gals...

it's a relief

brendan · 07-16-2009, 4:12 PM

if i shift up at 5/6000rpm i can get 200km till it needs to go on to reserve

today with riding it in the power band i've only got 160km to needing reserve

also it only got 11.5 liters last time i filled up

Thing is you dont get one of these bikes because of good fuel consumption, if thats what you're after get a 125 to commute on!

ture....i have a CBR125 as well...fun little bike

brendan · 07-17-2009, 5:22 AM

if you want MPG

you need a monkey bike

i had a 125cc monkey and with riding it flat out all day it still did 90mpg

cbrsam91 · 07-24-2009, 11:11 AM

im not sure what you have been reading about fuel consumption being poori. 1 got 76 mpg which is not bad out of the little beast on a steady trip to the coast the other day. and then i realised i was going to be late for work. and achived 28mpg on the way home

. which illustrates brilliantly how you ride it definatley makes a difference to your fuel consumption

As I've recently started a new job and am having to ride out of town I've started keeping tabs on my fuel consumption..

1st tank (not necessarily behaving myself anywhere) I got 45mpg
2nd tank (keeping to speed limits) I got just over 52mpg

According to my dash (its got a mile per L gauge) I can hit about 42MPG when I'm taking it steadily... at times it goes down to about 18MPG!

Sounds to me like you're either getting enthusiastic with the throttle or it's time to change the air filter, plugs, oil and filter. Maybe give the carbs a clean too.

thanks

when i got it i was told it only just had a full service so i would of for the plugs where good but it dose sound a bit lumpy some times

so it may need some new plugs

Surffrog · 08-04-2009, 6:13 AM

Remember, the more often you ride in stop start traffic the sooner she'll need a service. I've been to reading (albeit years ago) and the traffic is horrid there!

What I tend to do is give any new bike or car (new to me) a complete service on day one. That way I've immediately got a handle on service intervals rather than relying on the words of someone selling me the vehicle.

If I were doing a lot of commuting on my bike, I would want to change my oil and filter every 2000 to 2500 kilometres. If you only use the bike for long, fun activities, then extend that to 3,500 - 4,500. Just remember things can still need doing between service intervals.

Even if your bike was serviced when the previous owner said, I would very much doubt the carbs got a look-in. It would have probably (if you were lucky) included plug change, air filter, oil and oil filter. On older bikes the carbs are generally not looked at or touched in anyway until they start causing problems, and that's when we all jump up and down bitching about how bad carbs are.

yesterday i got 213km's to 12.6 litres = 47.9MPG useing Shell V-Power

Twincam · 08-09-2009, 1:04 PM

Got an update on the RXS (my sons bike)... For about 100 miles he managed to fill his tank up for £5.50 (or there abouts... Price is about a £1 a litre!).

My calculations have said he is getting about 75 (or just under) MPG.

update i got about 45mpg useing regular BP unleaded fuel

Surffrog · 08-13-2009, 6:56 AM

That could be the difference in ambient temperature or giving it slightly more throttle here and there. I would run at least one more tank to be sure, as long as the bike isn't complaining. By the way, what do you mean by low octane?
What are the numbers?

i think the low octane is 95Ron its just the standard BP unleaded

Then your bike certainly shouldn't be complaining with it. I'd run another tank of that stuff and do the numbers again. I bet it's as close as before if not better.

Hi all,

I'm using shell v power and getting about 220 - 240 km before the reserve kicks in - it seems to be about 11.5 litres to the reserve, so I'm getting pretty close to 60mpg - well happy with that!!
