A few months ago, I solicited help from this forum, because my 99 was running rough. It would only run with the choke on, and stall out at low idle. We (it was suggested to me, and I agreed) that we had some bad fuel, and I ran about half a can of seafoam thru her, and she did great. Rode her twice since then.
Last weekend, I went to ride, and it wouldnt start. Same problem. Got so frustrated, I actually killed my MF battery (and in this case, MF does not stand for Maint-free)
New battery, figured same problem, so I ran newer fuel and seafoam thru. Wont idle without choke, and sputters when I get on it around 50 or so. (Feels like a chain drive jumping the teeth on a sprocket, ya know?) At idle, it revs higher and lower without provocation. Choke off, dies within a minute.
I still think that it was bad fuel. My Father in law wants to take off and clean the carb, my Bro in law wants to clean the (3?) jets?
What say you? I dont want to take apart if I dont have to- I usually have problems putting things back on.
