cut out intrmitingly

[Ron M]

My bike is a 1987 FLHTC with CV carb , single fire ignition system, super trap mufflers, K/N air filter sifton 143 cam pingle gas valve. Sometimes when I start to accelerate the bike cuts out ,then comes back on. Give it gas and it tries to cut out . Increasing and decreasing revs keeps it from quitting completly most of the time.It does this for a while then runs smooth. Does it when engine is cold does it when engine warmed up. If engine stops I can restart immediatly and some time problem persists sometimes does not. This problem does not happen every day only occasionally Any ideas.

My fxrs did the same thing last year. It turned out to be a faulty ignition module. It would cut out cold and run ok for a while, then it would backfire stall and always restart after words. I only discovered the problem after the last time it did that, it didn't re-start. Hope this helps intermittent problems are a real pain and I don't want you to have to go for a wrecker ride and pay the big bucks like I did. Thank god for roadside assistance.:wall

Have to try to figure out if it's a fuel or ignition problem first, from there you can probably figure it out.

I really can't share those words and, if I did I'm sure they would be edited out, lol.
