12mm

i'm looking for the best drag pipe for my 4mil setup....what are my best options ?? its a 64.42mm bore 4mil vitio crank 34mm carb's 18cc domes we race 1/8mile on pavement if someone has a good set that will work good for me i'll buy thwm if the price is right. thanks

so if it's higher than 160psi i need race gas ??

well if i mix it with 93 and 110 i should be ok then? and what damage can be caused by running 93 on 18cc domes ?

I just built a 4mil stock cylinder motor and i'm wondering where i should be on jetting the bike has vito 4mil crank PRO C pipes 34mm carbs 18cc domes fully ported cylinders also is it ok to run good 93 pump gas on 18cc domes ? right now i have 160main jets in there......and im at sea level.

has anyone ever used a lighter flywheel or heavier one ?? if so what are the benifits of them ?

can anyone answer this ?

The bike i have them on with the stock carb runs good at half throttle but sputters at full,could not find the cause of the sputter but now im thinking maybe it's those spacer.

i have a question also. what power gains going from a 20cc dome to a 18cc ?

what would they do if you use them on stock carbs ?

what would they do if you use them on stock carbs ?

the porting was done by vito and the piston is cut on the exhaust side in the dome to except the larger exhaust port. i'll get some pic up of the piston and porting

WELL IM TRYING TO FIND THE BEST GEARING TO RUN IN 1/8MILE ON PAVEMENT....THE GEARING CALULATOR NEEDS THE TOP RPM'S TO GIVE THE RIGHT SPEED IN EACH GEAR. BIKE HAS VITOS CUSTOM PISTON,PRO C PIPES,35MM CARBS COOL HEADS 20CC DOMES,STOCK CRANK 18"TIRES

what is the rev limit on a banshee with a stock cdi box ? or where does it stop pull rpms ?
