Jet For Pipe Or Intake

[cdarb250]

Having a horrible time jetting my bike. I called FMF today and they said to jet 185 main 62 pilot 1.5 out 3rd clip. Rad valve and reeds say to jet 165main 55pilot 1.5 3rd clip
My new 38PWK AS came jetted 170main 55pilot.

Who should I follow FMF or Boyeseen or go in the middle?
I want to get it a close as possible because I still have to break in the new rebuild.
Need help please :bang: :bang:

I'd guess it would be better to break it in on the rich side, rather than break it in lean.

Starting out rich and going leaner is always more safe than starting out lean and possibly seizing up the engine.

Good point. I guess I should start with FMF specs first.
