Do I need to adjust my fuel air screw with Vance and Hines exhaust

I can't tell what your other posts says.

For any US katana without a jet kit, 2.5 turns on the air fuel screws is much better than stock. You can do an idle drop to find exactly what your bike will run best at (2.25, 2.75, etc) but 2.5 is a great starting point.

Sorry the bikebi got has Vance and Hines exhaust I'm cleaning carbs and noticed the pilot screws were way off one was at 7 other was at 6/1/2 and 5 and 3/1/4 so I was just wondering what do put the screw too after fully seating them

I need help again
New plugs clean carbs but still no low end power on take off it just chugs gotta give it like 5 RPM too take off

Seat the a/f screw lightly, then back out to 2.5 turns from there.


Are you letting it warm up with the choke on? Is it stumbling o ly when the engine isn't warm yet? Is it always stumbling there even when it's warmed up?

Thanks for the reply I let it warm the choke like doesn't work even when cold it barely goes to 1200rpm the screws are exactly at 2.5 and it sputters cold and warm

Small world. My sister moved up to Medford right around then, otherwise lived in the bay all her life.

So does adjusting the choke ever make the rpms higher? It definitely should when the bike is cold and first turned on.
1200 rpm is what it should be idling at normally, without the choke (once it warms up at least)

Definitely a small world so in played a lil with choke this morning and its very touchy but I got it to high idle that's good. But I still have no low end power as far as taking off I have to ride the clutch to get it to go steady otherwise it just boggs then will smooth out when I'm on highway doing 80 it does good my commute is 60 miles round trip so it does well at high RPM just not low
