Better to keep quiet and be thought of as a D!ck Head, than to open your mouth and remove all doubt.

I'm going to change carbs from the current Dell'orto 24mm to a Dell'orto PHBH 30MM

Main reason for the change is I'm looking at increasing the mpg from the current 24mpg and also the scoot will not run right on the current carb even though it used to but the slide does look worn as does the needle

The carb I'm looking at as the following:

145 main

45 pilot

60 choke

AV 262 Atomiser

40 slide

X2 needle

No float jet present but have been told a 300 will be okay

Gearing is 19/46 Indian GP200

Exhaust is an old style Mark Broadhurst Devtour

Any help will be greatly appreciated,are these jets etc okay,what clip should I have the needle?

Also it will be run without an air filter

Cheers
