It turned out to be clogged air intakes, shop cloth and wad of paper towel I had inadvertently left behind. Thanks for all the input and I'm thankful it was not something serious. Replaced the plugs, as I had fouled them out. Happy to be back on the road again. All the best to all of you!

I did disconnect the battery as was a suggestion and no difference. More later.

George, I have done the following: 1. Replaced the fuel filter. 2. Checked for moisture in the fuel and nothing. Regular user of Seafoam. 3. Installed the fuel pump from my son's RSV and no difference. 4. Unit starts fine without choke on these warm days. 5. Idles smoothe. 6. When applying slow even acceleration on stand in neutral, it raises RPMs to a low moderate level and then bogs down as if not getting gas and will stall unless you let off throttle. 7. If you accelerate aggressively it will bog down just as above. Note: This failure took place immediately upon hitting the rev limiter in first.

Changed the fuel filter today and checked for water in the fuel. No water/no change. I plan to pull the fuel pump from my son's 99 RSV and see if it corrects the issue. Am I to understand that a defective fuel pump restricts fuel flow of a running engine with over 1/2 tank of fuel?

Gary, hit rev limiter under load. Bike starts, idles normal, allows for slow rev and then upon reaching what I would call light to medium rpm it bogs down.

2007 RSV with 35,000 miles. Hit rev limiter in 1st gear and immediately following hit 2nd and now bogs down upon hitting full throttle. Need help.
