I will keep messing with it and see if i can figure out what is going on thanks for the input, so are 420's way to big in your opinion or could they be close? this is my first banshee but nowere near my first hotrod so I do not know were a baseline would be?

I the bike runs like a raped ape leave it,with a 420 main you betta be putting some serious hp out,it might run fine with the big jets if your port supports it.Have u run it against another good running banshee

i would look into your oil to find out about separation with colder temps and the specific gravity of the fuel you are using @ 3500asl. the higher altitude fuel will require 2 sizes over sea level fuel, and, if it is separating, the jet size will need to be larger at the begining of a full tank because it is trying to pass the thicker premix, which could also account for the white/black insulator. just a thaught :shrug:

 

also, if you actually aren't ported, check your compression next time you are at sea level, before you ride. 20's and +4 are risky for detonation below 1000asl

As far as i could tell the timing is not +4 but i know in a 300 ft race against my 250r with a pilot 410 top end on it we are meeting up at the end and my 250r is about 65 Hp so it is running well. I kinda think you could be correct on the oil seperation but i mixed a gallon today after draining my tank mixed it as best as i could and agitated it and ran it and the plugs darkened up a bit, I also had a small gas leak coming from the right side carb bowl that i fixed which could have been a small air leak I doubt it though. Thanks for the help guys I think Im gonna run it and if I blow it up Ill go to a cub top end
