There's a few thing's that could be wrong?
Your running way to rich,has the trike been sttting for a while and the carb got gummed up and or is the air filter clean?
Could be a bad plug too?

bike hasnt been sittin,filters ok,maybe too rich,it ran half a day saturday then kept fowling out plugs,what size plug should i use??

[russell56443]

NGK B8es or a Champion N-3,I like the NGK plugs better.

kool thanks ill try that

Another thought,did you get it recently from another state?
I got a Big Red from Arizona last week and the carb was set for that area,not up north where I live so I had to make adjustmenst for her to run right.

Cheap 2-stroke oil will foul plugs pretty easy.

Run the NGK plug and some good 2-stroke oil.

I was running champion plugs and cheap oil and was fouling plugs every couple days - I switched to NGK and good oil (amsoil) and haven't fouled since.

btw - post some pics of your trike man!!

my 250r fouls plugs if i jus idle around alot. but even then its not often. i use B8es and lucas 2-stroke oil and it seems to work fine

what fuel/oil ratio are you mixing? the sticker has it way too rich, 20:1 will do that. I run 32:1 with mine. Synthetic Golden Spectro
