about 2 months ago i post on here about my jetting all ****ed up. its pretty much right now. i have a 170 main, 42 pilot. when i had the problem before, it was popping and back firing on the spot when i was reving it. that problem is fixed now. but when i am riding and i let the throttle off it does all these little pops, is the bike still a tad too lean ? should i put in a 45 pilot jet ?
