Looking for base jetting suggestions.

[MLack]

Hey folks. Just wondering what a good start with jetting this would be. I have looked through the PINNED thread but couldn't find anybody with my mods and similar elevation. So here is a rundown of the mods:

 

- FMF Fatty w/ PC-2 silencers

- Wisco Pro-lites

- Stock carbs

- Foam filter. No lid

- Stock head shaved .020

- Stock cages w/ Boysen “Power” 2-stage reeds. (I may or may not end up porting them, not sure if it makes a difference tho)

- Stock porting

- +4deg ignition timing

- 50:1 Amsoil.

 

- Under 1000ft elevation

- 70-90deg with little humidity.

 

 

I am thinking 290main, 27.5pilots, 3rd clip on the needle, and 2turns out on the screws.

 

Thoughts suggestions comments??

 

Thanks guys,

-Matt

Yes, that is where I would start. It is a safe setup! do a couple WOT runs and check the plugs to be sure.
