I rejetted a few weeks ago to 130 mains,pulled the 3 snorkles and cut 1.5" hole in bottom of air box and added UNI filter,pilot is stock I noticed on the New Glarus ride that in 5th gear and runnin about 75/80 that when I rolled on the throttle it just lugged. I tried choking it a bit a couple of times going up hills to see if that helped to no avail. Where did my top end go? Any thoughts? Slould I put some resrtiction back in the air box? How about upping the main?
