Well, I still haven't pulled the plug yet... was going to do it several times, but either I'm too busy with other stuff or it finally quits raining and I can ride...
Anyway, I'd like to jabber on this topic a bit.
I had a 67 Bonneville, twin Amal carbs, no electronics. It ran the same every day, rain or shine, hot or cold outside. No electronic gizmos to tell it how to run. If it didn't run the same, you knew you had a problem.
With my 03 America, there are days when it runs "odd". Not bad, but not "right". A seat of the pants thing. If I stop for any reason, gas, cigarette, etc., shut it down and then start it again, it will run like I think it should. Stronger. The exhaust sounds deeper. This has been since it was new. I even posted this on here years ago and others noticed the same thing. We chalked it up to weather, engine temperature, altzheimer's, etc..
I'm now wondering if the TPS and the ignitor don't always see eye to eye as it were. I have no idea. Just typing out loud.
If the warden ever releases me from honey-do ******, I'll finally disconnect the thing and see if it makes the difference.
Now, back to our regularly scheduled programming....
