put in a 290 main and adjust your air screw. it should be close. going to have to do a plug chop and mess with the air screw to get it just right...

 

[CARNZ]

start with a 280~290 and plug chop from there

270-300 i believe is what most are running with and without the airbox lid off. the pilot im not sure of thought

 

[hudack]

if your runing a air box lid try a like a 280 and go down or up if needed and if no lid try lik,e 300

^^Yup. I was right on with a 290 main after doing some checking. Your stock pilot jet should be OK for those mods, though you can bump it up to a 35 if the engine won't idle or accelerate off idle well, despite playing with the airscrew.
