With mods in sig stock carbs 1100 ft!Gonna start 320 mains needle 3rd clip but what pilots? 25's or 27.5? Anyone with 25 think they will handle 27.5's.

i'm running 25's on mine, but i think i need some 27.5's. gonna rebuild my silencers and then see what they want. it's about where the airscrews wanna run.

I have 25 in mine and dont have any noticeable problems to speak of from jetting.

 

I tried 27.5 on it once and it bogged really bad, been good so far with the 25. every engine is different.

Your kind of in between the two sizes with your mods. I would run the 27.5, then try the 25 and see what feels better.

 

Also, your motor could probably benefit more from a dual stage reed, or some carbon tech low or mid tension petals. The high tension reeds arent really meant to be ran with a pipe like the pro circuits.

Shit the 27.5's worked great! Also using 320 mains needle on 3rd clip! It fn rips hard now. I like these alot better than my previous Fatty's!
