I hope i am posting in the correct area, if not let me know. I will give you a rundown of the last month. I got the bike after it sat for 7 years. It's a 93 sportster 1200 SE AF Santee drag pipes Possible Dyna Jet not sure what jet sizes professionally rebuilt carb new battery oil change new autolite 4164 plugs carb set at 2 1/2 turn out new intake seals and checked for leaks. I have ridden it for 140 miles, i am using 91 octane with seafoam. The bike runs ruff, backfire out the exhaust, some carb coughing, and slow RPM drop from a rev. Seems to have good power and likes 3000 rpm, but 2500 rpm it will surge. Hard to go slow in first gear. Idle will set at 900 and then go to 1100 rpms. No apparent reason. I have a picture of my plugs but don't know how to attache it. I am afraid to lean it out any more because i was told it could cause damage. Not sure if there is a timing issue, but plan to purchase a timing light. Am I expecting to much for a bike that sat for such a long time and just need to ride it, or should i continue looking for a problem? Thank for any help you can give me.
