Sorry, but I’m not buying it.
My bike started idling a little rougher than normal a few months ago, especially when the engine was cold. Last time this happened I found a badly corroded spark plug wire. So the first thing I did was check all the connections associated with the spark plugs and coil. Everything looked good, so I ran some Seafoam through the tank (2X), changed the air filter to the new Loydz filter, changed the plugs, and looked for any loose hoses or electrical connectors while I had the tank off. I also tried to figure out how to get to the throttle body without major disassembly. I didn’t find anything out of place, nor could I figure out how to clean anything. Despite the tune-up there was no improvement. More power, yes. More intake noise, yes. Better throttle response, yes. Smoother idle, no.
The problem has continued to get worse, and your comments have me concerned. Any engine that breathes in fumes off the crankcase will need periodic cleaning of the throttle body to remove deposits. I can see no way around this. The oil mist builds up as gunk around the butterflies and in idle passages. Eventually air just doesn’t flow like it should at low RPMs and you get a rough idle. Every engine that I have owned has run better after a good throttle body cleaning. The more miles between cleanings the more dramatic the improvement. At 23,000 miles this throttle body probably needs a good cleaning regardless of what the book says.
Maybe I have a screw loose here... please someone explain to me the flaw in my logic.
