      My carburetors have been jetted to a 100 / 97.5 Is this to much I have straight pipe exhaust and aftermarket air filter??

      I think the best setup would be 92.5 & 95 max because the GV Aquilas do not like any air modifications to the air intake airboxes when using the OEM carbs & OEM parts.   The OEM air filter is more than sufficient for a 400cc motorcycle.   Keep the pilot jets at size 20 on both cylinders.  They hate pod filters and will usually show their mood with lack of power and difficulties in optimizing a “pod” setup

      The exhaust may be a little beneficial if we use OEM  2002 twin exhaust pipes because for some reason i’ve known that the GV’s really perform best with their old style twin cans.   If it is not possible, try to find similar size cans  (that reach the end of the swingarm) , like what LeoVince does for GV250s and Gv125s whilst still giving good power and noise 😉

      Take a look at the plugs , if they are jet dark, then your jets are too big but i think 95 is a max sweet spot 🙂
