i have a 2009 vulcan 900 custom that has right at 9000 miles. It just recently developed a problem of bogging down with anything more than 1/4 throttle it will bog down and i might as well pull in the clutch and let it idle. If I start it up in the morning and let it come down off fast idle and take off it will be fine for about 10 minutes then start acting up. if I stop to get gas or whatever then come back out it will be fine for another 5 minutes then act up. Also the longer I ride it the worse it gets. It will do this in every gear and even in the driveway sitting in neutral. Any and all help is greatly appreciated. To add to the post I have previously replaced the stator (since it was no longer charging and killed the battery), I had vance and hines slash cut exhaust on it but put the stock pipes back on to see if the problem went away which it didnt. I have a video of it showing what its doing but Im having problems uploaded on here. It says mov format is not allowed. Anyways I hope you guys can help.
