I did a rejet on my 95 sportster. I have installed Screaming eagle pipes. I have been going nuts with the final adjustment. when I opened the carb up it had a #48 slow jet and a 170 main jet. Here is what I did. I drilled 1/8 hold in the slide. cleaned the snot out of the carb, replaced the main jet with a 175 main. Started the bike up and tried to adjust the fuel mixture. I was told 10 different things by ten different people on how to do the adjustment. I just can't seem to get it right. when the bike is warmed up, and I start off, the bike knock's, I think it is bad gas. I have accel plugs installed and everything seems fine. the fuel mixture screw is out 3 1/2. should I set it in more and raise the idle screw. is that how you do it. idle screw in and less on the fuel mixture. please someone help. I am ready to give up.
