just picked up a tw tonight that had sat for a few years heard it run at the guys house but not long. said it had old gas in it and wasnt running right. i took his word for it. got home dug into it. changed the oil (was black as you can imagine) and put fresh gas in it. along with a new plug. now the bike starts easy and runs alright but while sitting and idling it will pop and spit once in awhile and want to die out. giving it gas doesnt really help either. is this likely the cdi? i know this year is bad for the cdi's going out. and was hoping the whole time i was picking the bike up that it would be one of the few that doesnt have the issue. no such luck. if it turns out to be the cdi. does anyone know what it will take to convert to the newer style? it already needs a new left side cover so it might be worth it to upgrade the whole system. funny how. "ready to ride" really means i need to dump another grand into the bike i feel like i over paid for already.. such is life though. any advice about any of this would be great.
