only other reason it would spit is if it were running too hot. So then we would need to know all intake, engine and exhaust mods and exact jetting, your location weather and altitude, and riding style. Then someone will ask if you did a plug chop, and how that looked.
BOTTOM LINE = NORMAL.
relocating bottle will help, but I think most people here will tell you if that is all you are noticing and it is not GUSHING out then it's just fine.
Just watch it and see how and when it is doing it...does it do it no matter how fast you go......or only when goin slow......or is it a drip, or splooge.
good luck
