Starter/compensator issue???

Please help! I have an 08 Electra Glide and when I hit the starter, the starter engages and motor turns, but stalls and seems to turn backwards. On occasion backfires thru air cleaner.Put new battery and still same issue. WHEN it starts it runs great with no unusual noises. Loud cluck also. Suggestions? Many thanks!!

Also eems you have a a bad compensator too that would explain the loud CLUNK (*BANG) noise when trying to start the motor thats a classic sign of a bad compensator.

If the motor has had perf mods that increase compression that could be adding to starting issues too.

a motor always stops on the compression stroke...so when you try to start the motor it is at the highest point of resistance

when I start my Harleys, I flick the starter button.

this turns the motor either past top dead center, or it rebounds and the piston goes back down the bore.

either way when I next press and hold the starter button it can build some rotational momentum before encountering compression.

103 models have compression releases which solve that problem.

on my bikes I flick once, then press and hold.

except for the panhead

If just doing it when cold just reduce it by 3 in the temp area. If doing when hot or cold you can reduce the entire area 3 to 5. Be ware if you reduce too much it won't start one morning. It also may not want to start when hot if too lean either. The other thing is clean the IAC and Throttle blades as the problem you are having is too rich. If all that fails I would have the starter replaced or atleast the starter drive gear. It has a sprag clutch in it and sometimes it will slip and do same thing. Most of time cleaning and or reducing the starting fuel will help. If you have cams in it even more important to reduce cranking fuel.

Went through the same thing last summer, put a on new compensator before it kills your starter and leaves you stranded. (ask me how I know). I put a SE comp on mine because the Baker comp was on a 4 week wait at the time.
