Which is what I was saying in post 52
Do you realise how many holes there could be if people would just take the time to take the dirt out of them?
Re: BMW R1150GS
From the Wiki, speaking of upgrades from the previous 1100GS: An anti-knock sensor adjustment change allowed the adventure version to run on lower quality gasoline as well.
From here: https://en.wikipedia.org/wiki/BMW_R1150GS
So, sounds like the electronics can detect and adjust via the ignition/fuel injection.

Wow nice dredge.
Anyway while I'm here, what's wrong with 95?
Nunquam Non Paratus
I Have a 1993 Kawasaki ZZR 400, what fuel should I be using? according to the specs it has a 12.8:1 compression ratio. and I'm using BP 98
but not all BP stations have 98 at there pumps
It's also in bad need of a tune but no bike shop around seems to be able to get it right and is running way to rich... I did a run up north to
Whangarei from west Auckland, 182kms to my destination and at 171kms I had to switch over to reserve. I use to get 230kms!!
So before I take it to someone else to try and tune, I want to put in the right fuel to start with.. Would 91 be sufficient? or 95?
Cheers
With the compression I'm thinking 95. 98 is fine too if BP is local. Bet you don't notice any difference between the two.
Mind you I bet the compression is south of the original figure by now.
I’m a huge nerd when it comes to economy and fuel types. I have a huge spreadsheet for the car but I’ve not got round to starting one for the bike.
My manual says I can use 91 or above (honda spada), as well as ethano fuel up to 10%, but NOT methanol (because everyone with a 250 has an abundance of that).
Anyway so far:
Mobil 95: 8.63L, 211km.
= 4.1L/100km
= 24.45km/L
Gull 91:
207km, 9.69L.
= 4.68L/100km
= 21.36km/L
Mobil 95: 199km, 8.71L
= 4.38L/100km
= 22.85km/L
The result I have for 98 is no good cuz it pretty much spat the dummy so I won’t post them.
fark the cbr is a boat compared to those, im getting ~ 11 KM/L ._. and trying to be sensible most of the time
AllenB. No I don't notice any difference at all between 95 and 98 so I am thinking of going back to 95. But if I can, I wouldn't mind using 91 if my bike could handle it ok...
Yokohama.... These are the figures i use to get...
Gull 98 Bio Fuel :- 230km to 16 litres
BP 98 :- was similar at 229km to 16 litres
Caltex 95, Z 95 were the same at 220km to 16 litres
G.A.S. 95 :- 180km to 16 Litres and bike ran like a piece of S###
Discovered that I shouldn't have been using Gull Bio 98 due to the ethanol. And have been told this may have screwed up the jets in the carbs..
So I may have to get new kits for all four Carbs..
