ive read alot of posts on here and E2s, about amsoil being total crap and motors lookin like crap after using it and tearing down after the season, and there being absolutely no advantage (except saving money_) to running such a lean ratio mixture, some of the more knowledgeable guys ive seen post that bikes they have tested actually make more power wiith a 32:1 mix, please dont attack me, im only stating what ive read from alot of knowledgeable guys- either way i wouldnt wana risk blowin/lockin somethin up over an ounce of oil per gallon
and to the OP - read the plug chop thread and it will explain how to fine tune your main jett, no one can tell you anything from looking at a 2 hour plug, get your main jet dialed in and go from there with the rest,, if i were you id ditch the ai4r box lid and jet accordingly, they cant breathe with the lid on, weather the snorkel is on or off
