Hi guys.
Again, I come to this forum seeking advice and assistance.
I owned a 2003 FLHT standard with a stage 2 upgrade - pistons, cams, adjustable pushrods, Screamin’ eagle ignition module, etc.
Over the past 3 years, I've put 3 new starters in the bike. The last time, I had to replace the starter, outer clutch and pinion gear.
I know a lot of other Harley owner's with "boosted" bikes, and none of them seem to encounter the same starter problems as I’m having.
There are times when starting the bike I get a very loud "crack" as if the compression/spark is forcing the starter backwards. There are also times when the starter "goes quiet" and I wait about a 1/2 of a sec. for the current to force the starter to turn.
I’ve been told that this is an ignition problem, the ignition being too far advanced. Yet, the module that I have installed does not allow any adjustments.
Could you offer me some advice as to what I should do to correct this problem?

Thanks
G

 

What is your compression?
Sounds like a weak battery. Depending on compression you may want to install compression releases.

 

In my opinion, the stock starter is only just adequate for these motors. Even in stock form. Your stage 2 motor may be higher compression and that works the starter hard.

If it were me, I'd think of replacing the stock starter with a 1.4kw starter. Stock is .7kw I believe. Make sure you have good clean cables and connections as well.

Ignition timing can cause it to seem like it is dragging too, but in this case I would think that that is not the issue. Of course the only way to be sure is to check the timing.
