Starting problems, ignition???

[Berserker]

Looking for some help. Also posted this as VTF. Open for any suggestions.

LAst year put in Crane fireball. Wouldn’t start one time unplugged and plugged in, after screwing around with for awhile. Was humid out, that maybe moisture. Few days later, would not start and put stock back in ran replaced with DTT.

Left on vacation, with a DTT. Got in the mountains, and would not start. Put in stock started, DTT in nothing. Ran stock for few thousand miles. Replaced volt reg thinking it was frying them, had some burnt out bulbs. Also replaced CPK sensor cause I had one, and had VR off.

2k miles later stalls after coasting down big hill. Though I flooded it. Hard to start. Backfired few times, finally started.

Yesterday, rode about 20 miles, gassed up, had hard time starting. Rode 15 miles started fine. Rode 2 miles home, stalled as pulled in garage, good timing. Would not start. 20 minutes later still would not start. Put stock in fired up. 10 minutes later tried DTT fired up too.

Yesterday big storm was coming and temp dropped. Barometric pressure drop? Wondering if map sensor?

Also have been getting a bit of pinging lately, more so then normal. Though I ran fine on vacation. Wondered if I was getting bad gas or running 80 on interstate, cleared up carbon? Dunno. Maybe not related.


Either way when it does this, the bike turns over. Back fires, sounds like running kinda slow, like its about to start. I have tried with aftermarket nothing, plugged stock in and fires up. Sometimes putting aftermarket in will start up, sometimes not.

It seems to like stock, but if you wait long enough, seems to run aftermarket. Smoked a start clutch out of town last year. Few days later, started up. At the time I though plugs were fouled, kinda black.

Went through 2 ignitions, manufactures gave me new ones. They said could not find anything wrong, but said they don’t test for everything.


Trying to include everything. Internet is down at my house so will check again when I can.

2001 FLHR, 16k miles on 98”, 50k on bikes. 9.7 cr, Andrews 37g, SE44. Battery is 6 years old, but cranks fine. Replaced volt reg , plug wires, and crank sensor. Used lots of dielectric grease in ign connectors.

Also been having lots of hard starts when hot. Don’t remember this many last year, does it all the time now, even after few hours. Been hitting starting button quick, and then starting. No grinding then. Maybe was as bad last year, didn’t think so.

Any help appreciated.
