push to start

[harryparatestee]

1999 Titan Gecko with an S&S powertrain.
I was explaining to a client that my Fatboy had a miriad of recent problems that were finally resolved and my client was having trouble starting his bike. The starter sounded like it was frozen and would do nothing but click once. I pushed him down the alley in an attempt to start (no man, you have to have it in gear before you dump the clutch!). It didn't start doing that but upon getting back to his garage I pushed the starter and VRROOOOOM!
Since then he has asked me to ride it when I come by, which I do. Last week he called me and said it happened again. He rocked it back and forth a couple of times in gear and she started.
Something is stuck but I don't know what it is besides the starter. Any ideas and why?
As always thanks in advance.

Sounds like the jackshaft gear is hanging up on the clutch starter ring. Could be due to a work jackshaft, gear, bendix, primary cover bushing or any of the above combined.

Check all electrical connection regarding the battery, ground strap and starter as well.

Also....make sure the starter bolts are tight, and starter to inner primary union is clean, because that's where the starter gets its ground from.....

Dave is right on target all the above will cause that could be as simple as the jack shaft bushing in the jack shaft cover i'm assuming your runnimg a open primary belt drive
