@ tlnut> can you get a graph up of that? Also - what airbox and filter are you using?

ref the post above yours - CRM was telling our man Brys to RTFM..RVF carbs do not come under the this thread at all.

They are different beasts.

On yours...pilots are wrong, needles too high and too big jets. Where you at in the world?

Have you got a dyno chart you can put up (and list of all mods exact carb settings etc)?
