Wet spark plug!

[FlexBusterman]

Hi everybody. I have a 2004 Banshee with some mods. Here they are: port cylinder, crank mod, head planning, boysen reed, full pro circuit line, timing key, open air filter lid with k&n and boost bottle. 310 main, 27.5 pilot, br8es spark plugs. I've tried alot of kind of jetting but my spark plug always run wet. I've opened the engine and reseal it for be sure they don't have leak between the crank case and cylinder head. But it's always the same. I no it's hard to fix an engine in the net but if somebodys can give me some tips, I will appreciate.

 

Thanks.

Try some 290 mains, and report back the results.

you may be to rich and thats why your plugs are wet.. but generally your plugs will always be alittle wet simply because when u kill the quad the engine rotates a few more times without firing there for spraying them with gas that wont be burned.. if they are completely soaked in alot of gas then your jetting is probably rich. the best way to resolve your problem is just to do a proper plug chop to determine your jetting and once you do that and it comes out correctly you should be fine. heres some stuff to hopefully help you out:
