so i bought a superhawk and it would run on one cylender when i started it up, so i droped the needle and put new plugs in it and it seems to run good but a little weak in mid to hi end, but idles perfect and runs decently smooth, when i rode it and it was a little less powerfull but the airbox cover wasnt on, i cant seem to get at the mixture screws with the tools i have, would anyone recomend me getting the tool to adjust it or should it run good with the airbox cover on? btw the airbox cover and filter wasnt on because i had just cleaned it and the filter was still wet
