The right Jetting

[PowerBand22]

Hey guys this is my first time on the forum but I was wondering what would be the right jetting for my blaster. I currently have an open airbox,milled Head, p&p “that I did myself lol” Vito’s reeds, fmf gold series pipe and advanced timing.

Was recently on fmf site and IIRC it calls for a 260, holes in box lid, everything else stock. Depending on elevation start with a 300 and work your way down. Plug chop to confirm that it's correct.
WELCOME !!

Now how do I make sure I don’t take the jetting down too lean

When you get a hole in your piston, you're to lean

Mostly just plug chops. Plus it will sound flat, wwaaaaa.
But you want to stop before you get that low.
