HELLO I LIVE IN FLORIDA AND I JUST BOUGHT A BANSHEE IT HAS A ATHENA BIG BORE 392CC KIT , CPIs,BIGGER CARBS ,AND A 5MIL CRANK WHAT RATIO DO I USE AS THE MIX AND WHAT OCTAIN GASS DO I USE ? PLANNING ON GOING RIDING IN THE MORNING AND THE PREVIOUS OWNER OF THE BIKE SAID HE ONLY USES 110 OCTAIN FUEL AND WHERE I LIVE ITS HARD TO GET THAT SO CAOULD I USE ANOTHER OCTAIN?

DO A COMPRESSION TEST AND SEE HOW MUCH PSI IT IS KICKING, OR PULL THE DOMES OUT AND SEE WHAT CC THEY ARE.

32:1 TO 40:1 WILL BE FINE !!!. 

DOES IT HAVE A TIMING PLATE, MAYBE YOU COULD BACK THAT DOWN TO 0 AND RUN LESS OCTANE.

 

 

LOUD NOISES !!!!!!!!1

First off, wtf with all the caps we're completely capable of reading without it, if anything it makes it more difficult. Secondly, octane needed is based on your engines compression ratio. not entirely the same thing as cranking compression but its usually a good indicator. Using less octane then required will cause detonation/preignition and will melt your top end. If the previous owner was running 110 i probably would too untill i verified if i needed it or not. check http://www.racegas.com/fuelfinder for something local. good news is many times people run race gas with out the absolute need for it you may be able to get away with premium pump gas like 103 if you can find it or get some octane booster it can work in a pinch. I just wouldn't always use it as it doesn't perform as well as real octane. do what dardy said, check those things and you can get a better idea what you'll need.
