Hello, I'm a new member to the Forum. Last Monday I purchased a 2008 CMX250 Rebel with 5,400 miles on it. It was really stumbling when I tried to accelerate, and the seller had the idle screw set for pretty high rpm.. I rode it home 69 miles. Before leaving for home I added 1.5 gals of ethanol, and aired the tires. The bike got stronger as I rode it home. I added another gallon of fuel at home to top it off. I dropped the idle rpm and it will run all day at idle, but when I blip the accelerator it stumbles severely. Twisting the accelerator quickly gets it through the low rpm stumble, and it runs fine above the low rpm stumble. I've added carb cleaner, and will run the bike every day to use the current tankful of fuel and carb cleaner. I'm wondering if I'm barking up the wrong tree thinking this is a clogged carburetor. Any advice?
