Can someone help me out with jetting. I am currently collecting parts to build my Blaster. I just had the cylinder bored out to 67.5mm. I am going to do the Ken O'Conner DIY port job very soon with milled head, I have an FMF Fatty pipe and Power Core 2 silencer, UNI air filter, will be running no air filter lid. I just had a Keihn PJ 34mm carb and a nice billet intake given to me.The carb came with no jets and I know nothing about jetting. Can someone give me some advice on what jets I should play around with to get started? Any advice would be great. Thanks guys.
 
i run that very similar set-up carb/intake wise, with kens trail porting, f7 exhaust cfm box with a uni in it

my settings are .........45 pilot, aircrew under 2 turns out, dgh needle < (very important "dgh" or "cel" needle) on the middle clip, and a 155 pilot for summer, 162 for cooler months

that should get you in the ball park, prolly end up with a smaller main for the fmf versus f7 pipes, and kens porting versus diy style
but that'll get ya started
