I will try different set up tommorow
do you know what jets and needle you have now? once you do you can start jetting

its wierd because those big bores ive found out usually dont need any more gas, in fact since compression is increased and combustion is more efficient you can usally lean the jetting a bit...

let us know

looking real nice! very nice

ps. what did you use for header wrap?
