Way too much oil. Your plug is most likely fouled. 13:1 is way too rich with oil but at least you didn't burn it up. Like azkronic said,"can't say it wasn't lubricated"
lol i know too much oil. the smoke gave it away today. i deluted the gas down a lilbit it idled fine for a while but quit again after riding(this time i was "smart" and didnt go far) Im jsut going to drain the gas and do it all over.
If you are going to err, its better to err on too much oil than too little. Too little will fry your engine. Too much will kill every mosquito in your neighborhood.
