First things first. Great Site. I have already learned a lot about the 84 700 LTD I purchased last week. It's a nice bike for the few dollars I had to give for it. It has a 17,000 miles on it and from what I can tell has been very well maintained for most of it's life, with the exception of the last owner. She only bought it for riding around her yard, SMH.
I have a few issues with it that I have learned about so far. First I'd like to address is the rough idle. It's very cold blooded, especially at the beginning of the day. When I leave for work it's only about 50 degrees and doesn't want to idle without choke for about 10-15 minutes of riding. Once it's warmed up it idles at around 1500 rpm's, but misses on at least one of the cylinders.
It doesn't currently leak fuel, that I have been able to notice, from the petcock or carbs. Also, this is the first week I have ridden it on the road, still burning the first tank of gas that I put in it.
My plan of action is new plugs/oil&filter/air filter and an inline fuel filter. That should make sure the problem doesn't get worse.
Beyond that how should I tackle this rough idle problem?
