or a keihin pwk 28

 

[Blasterr525]

thanks man, like what is the number? like idk what it stand for? different sizes or what?

 

[brandoz28]

yes, the number is generally the size in millimeters


and if you really have a 240, i'd get a 34mm pj or a 35mm pwk

 

[Blasterr525]

yeah its a 240 and like the size is the circle that goes into the boot?

 

[Zwiser]

oh i didnt see you had a 240 but yeah you want a 35 to find that monster and the # is the size

 

[brandoz28]

its the inside diameter of the opening the side that goes into the boot


and a good 33mm-35mm carb will be the way to go

 

[tyler1blaster]

do you have a 240bbk or did you just bore it .40 over? totally different things.

 

[Blasterr525]

bigger carb mens more airflow or gas through? or both?

 

[Blasterr525]

the motor is bored 40 over

 

[Zwiser]

wait how big is your piston is it 72mm or 67mm or 73mm

 

[blasterfreek30]

as said above, look into a 30oko or a 28mm pwk...great carbs for stock to mildly modded

 

[Zwiser]

^^^ he says he has a wiseco bbk

 

[brandoz28]

if its bored .040 over, its not a 240


and a 28-30mm is adequate
