  1. I'm have issues with my bike and could use some assistance. It runs good for the first 15 mins and then starts bogging.  I have oil coming from the header pipe. I changed the jets and went smaller. still bogging. I thought it was rich because the plugs were black. I ran it with the new jets and cut the plug. jets were 175/50. anybody in New Orleans that works on banshee's?

  2. You are going to have to keep your compression down around 155-160, probably have to have a 23 or 24cc dome. I am sure Noss can hook you up. B)

    thanks all

    i just talked to kevin and i need to change the domes to 24's

    i was wrong on the domes i had they are 21's

    i ordered the new parts.

  3. Yea, what the other guys are saying. I wouldn't recommend 20cc domes on a stock motor at sea level on pump gas. Detonation will lift the domes and blow the oring. When you put it back together, run larger domes or higher octane (or both).

    hey david i talked to you about a year ago.

    its the same problem

    its a 4mill cheetah cub. no porting

  4. What fuel and octane are you going to run? If you run a 21cc dome you will have around 185 on the compression at sea level that would require staight race fuel. If you are going to run pump gas then you would have to run around a 24cc dome. Since you have a 68mil bore that is a big bore so you are compressing more air, so a 21cc dome on a stock cylinder bore will have a lot less compression than a 68 mil bore. So what octane of fuel are you going to run?

    93 pump gas
