Just bought my first Harley. It's 16 years old and actually in pretty darn good shape for anything 16 years old. $7000 for verified 12300 miles. No wobbles, starts right up, runs like a top when you're in the right spot in the throttle. She passed inspection and I replaced all the fluids so all the oil is good and I regularly check the levels etc. My problem is the carb (I think). At about 1/8 throttle right where the power should start I get a bog or sputter and small backfire type sound and it bucks during takeoff. I ran out all the old gas, ran two tanks of new through. one tank with water remover and one with fuel system cleaner. I always run highest octane I can get. It's been 93 octane so far. I changed the plugs and wires and air cleaner and shot a half a can of carb cleaner through the carb. Cheapo fixes for sure but I gotta start somewhere. This seemed to cure the startup bogs and low throttle bucking but after a days ride I started her up the next day and it was business as usual. Now I don't ride like it's a race so when I finally felt the need for some above average acceleration I gave the throttle a good twist and the bike bogged and lost power. Maybe at a quarter throttle she runs like a champ but higher and I get a bog-down like it's floodin, but I wouldn't know. I noticed the smell of gas when I park until a wise bearded man suggest that I turn off the fuel petcock when I'm not riding. Keep that in mind if you should offer tech tips. Tis bog accurs in third fourth and fifth. I don't know about 1st and 2nd because I shift out of then before that much throttle is needed. Now the wife and I are hefty and the bike hauls us around with NO problems. Lotsa power except for the throttle positions I mentioned. Everything seems stock. A mechanic off duty look at it and said it looks stock I should say. Any Ideas? Thanks fro reading my first novel by the way.
