Ok a question for he pros as personally I know kinda how a carb works but I'm not going to personally open it up etc etc. Now I have 4 single pod filters ( ram air 54mm) and I'm about to have a custom exhaust made 2-1 each side of the bike, ( bike is a bobber using a 1tx engine ) can anyone recommend a new jet for my application ?
For everything short of WFO, shimming the needle is far more important than the jetting.
Here's what I've done to my carbs,I run unipods and a black widow collector to dual ss70 slipons,42.5 pilots,brand new emultion tubes,needles lifted 2 4 millimeter washers on each needle and 120 mains,my timing is advanced 3 degrees.
