Default 07 FXSTC Backfires through exhaust, won't start
07 FXSTC with 7500 miles and ThunderMax. Rode her 2 weeks ago, no issues. Pulled her out yesterday, turned on the ignition, hit the start button and it backfired through the exhaust. Big time. Cranked it, continually backfired, turned it off for a couple of mins., tried again, same result. Checked plug wires all connections ok. Pulled the plugs, looked ok, but I'm replacing them today.

Any suggestions would be greatly appreciated.
Thanks.

Try removing the Thundermax and see if it starts.
