big bore ,squish band / fule rating

[bansheeboyo]

After a bit of thinking and saving im now in the position to buy a bigbore for the R.
i have been looking at esr and sphyinx is there any others you would recomend ??
where is the best place to buy from ?

Also for the fule rating ,the stuff i use is 99ron , 87 mon im guessing that makes it 93 pon ?
so what head do i get just pump gas or whats the story ?
also if it makes a diffrence the stoich is .... 14.7:1AFR or 14.4:1 AFR dependant on the station
cheers scott

it depends on the compression of the motor...

you can run 87,89 or 93 octane gas in the motor however your better off running race gas with lead in it over the gas from a pump... its mroe consistant and youll be able to jet your bike much easier the station pum gasses have all sorts of additives that make the plugs hard to read for jetting...


I m not sure what the gas is like in scotland though


and can you try to give up on hating? ;)

would running methanol be a option or is it to much hastle ?

$6.83 per litre? So that makes it 6.83*3.78=$25.82 per gallon :eek2:

At prices like that, I'd be much more inclined to go with pump gas, I'll gladly sacrifice a couple horsepower. What is the price of regular gasoline in your area?

well i run shell v-power in my Evo thats 99ron unsure of the mon mid 80's i belive its £1.49 a liter SO MY GUESS IS AROUND 2.39USD and that's per liter not gallon like you guys !!!!
i'think the tax makes up 79% of that price the B.@.$.t.@.r.d.$

I just changed to a pump gas dome because it was so hard to start with the really high compression head dome.
