I just got my Powroll Supertrapp today and put it on. 140 Main jet and moved the needle down one notch works great. My question is how many discs are you guys running? They gave me 18 and I haven't even messed with it yet because I wanted to subtract discs once and do it right the first time. Thanks!

 

It should of came with 8 discs. I'm running 14 now. I'm very pleased with the way it is going, a little loud but that is the way I like it.
