Happened for the second time yesterday. 2007 VFR with 3700 miles. First time. I had her up on the center stand and washed the bike. I then lubricated the chain and also adjusted the tension of the chain as well. While on the center stand, I started the bike. It cranked for about 2 seconds or twice as long as a normal start for a better idea. After 30 seconds, I backed out of the driveway and finally gave it some throttle as I went up the alley. It didn't take off as I expected. This could be normal as I am used to my carburated CB750 wanting to take of itself on cooler mornings with choke. I turn right at the end of the alley and shift from 1st, to 2nd, and then clutch disengage, downshift as I come to a stop. Idle was MUCH higher now and seemed to stay the same as it was in gear before slowing down, probably 3 to 4K. Still had a loss of power when the clutch engaged at this RPM. I took it home. Let it sit for a bit as I went inside the house, come out to troubleshoot and it runs fine. It has been about a month and it did the same thing this morning on a usual start up on the side stand. No wash, no center stand action. Just a morning like the mornings before. As soon as I heard the longer start, I got a gut feeling it would behave the same way. I let it warm up for a tad bit longer too. Sure enough at the end of the street, Idle went up again. This time I gave it a little more throttle and everything was fine for the rest of the ride. Thought it may be a vacuum leak but that doesn't explain the longer crank required to start. Fuel pump primed each time as well. Has anyone else every experienced this? I assume I will again in about a month or so. I never experienced this on my 03.
