Toomey pipes,porting ,timing advance and chariot head running 93oct fuel

[yukoner]

Hi there I have a banshee that is running stock carbs with porting,toomey pipes,cool head with 19cc domes,uni in box air filter with lid, +4 timing I am at 2400ft just wondering what any thinks the jetting should be at. I believe it needs to go up a pilot size I am running stock but it has a bobble off throttle but pulls good up top. Any suggestions would be great 

 

thank your u
