Working Combo! Jets and Pipe

I think this may have been stated before in several different posts but I putting it here all in one place.

I just installed an FMF power bomb header with the FMF Power Core 4 w/spark arrestor.

I rejected to a 170 main, OBELN needle on the 3rd clip and a 42 pilot jet.

Let me tell you, the bike is a friggen dragster now. It flat out rips.

For reference, Ive use this from sea level to about 3500' in dry SoCal conditions.


Your jetting sounds familiar. I tried the 170 main, but it was a little rich because of the stock uncorked pipe. I have posted the same results. It's like lighting up a top fuel dragster.
