Engine Missing

Fired up the Springer today after about a 2 1/2 Month layoff (finally got a nice day for a ride.) The bike started up fine but the engine missed every so often during a one hour ride at a steady speed (not during acceleration or deceleration.) The bike'sa carb'd '06, stock, except for a Stage 1 upgrade. Is the missingtypical after a long layoff from riding?

Any info much appreciated,

Dave

RE: Engine Missing

Were your riding on old gas? If so, it was likely just a case of bad gas. If not, the first thing I would do is change plugs.

RE: Engine Missing

I agree. Might be bad gas, but I would do a quick tune up. Check the plugs and wires. A lot of things can happen when a bike sits for a while. May have just missed you and is being a bit of a woman about it!!!

RE: Engine Missing

I was having the same problem. Mostly at lower speeds, 45 and under. Then about two months ago It started the whole time I was driving. I just "bought" it back from the shop. Replaced sparkplugs, wires, took carb off and cleaned, took MAP sensor out and cleaned. Now it only does it when you first take off and about 35 one time and not anymore. Mechanic says he doesn't have any idea what to do next. Have been using last three tanks of premium fuel from three different stations. Hope you find the answer to yours.

RE: Engine Missing

try un-pluging connectors at the ign. module. clean with contact cleaner, and reinstall. they can loose connection even though their snapped in. i think there was a tsb on this. only takes a few minutes.

Generally ignition break downs occur during high load conditions and since yours pulls fine under load I would be checking the carb out.
