power loss at elevation?

[Strm Trpr]

Is it ported? Im riding at 5000ft and im running 290 mains, stock needles in the middle clip, 25 pilots and 1.5 turns out on a non ported motor. Hope this helps.

I run this jetting at sea level on the ocean on stk cyl's with pods and T5's.

3.25 turns on the air screw is past the point of doing anything. Sounds like your pilots are too big. How are you tuning the air screw? Did you ever tell is what parts are in this thing?

 

I started at 2 turns out & went from there.. i figured if i had to go more than 4 turns out i would need to go down one size on the pilots. & i guess i said my carb settings at 900ft, but not the parts. stock engine internals & carbs with the tors off. FMF fattys & pcII's, pro-flo airbox w/foam filter & prefilter & no lid.
