Just a question ......
I noticed this many years ago, and last night, it happened again and I though...why not ask?
Typical get ready for a ride. Roll bike out and get it started, with or without choke as required. Bike starts, choke off and lower the revs to allow the oil to get out of the sump. Motor is running at about 500 or so and I go into barn and start to get my leathers on. This takes about five minutes or so. At about this point, long after the sump is empty and the bike has gradually increased in idle rpms...the motor suddenly picks up about three or four hundred rpms and settles into a faster idle. Almost like something warmed up, opened, released, or lord knows...the bike just runs faster.
I have a Boyer in it, always did, normal 932's, same happens with or without oil cooler, no choke on....absolutely nothing that would cause this...that I know of.
This is where you come in. Anybody else noticed this? Any ideas why? No...I'm not dreaming..this I have noticed at least a thousand times, over at least 30 years, and it just annoys me that I can't figure out a reason why this happens. It causes no damage etc, but it makes me curious. Some electric thing? Is the boyer warming up and changing the timing? Check your machine out, and let it warm up for five minutes and listen for sudden increases in the rpms....and let me know what you think.....
