My 04 Fatty currently has Samson Big Gun 2 Streetsweepers with 1 3/4 inch head pipes on it. I'm switching to V&H Big Radius pipes and I was wondering if you guys think I'll have to re-jet. If so, what sizes should I use. The bike runs great with my current jetting but I forgot what size jets I put in. Thanks in advance for any input.

 

I would say take a look at your plugs. If they're OK and you don't have any popping on decel, leave it be or take it and get it dyno'd.

Let your plugs tell you what to do............kinda "Zen" sounding don'tyou think.


Good luck
