I've got a 2008 gsxr600 I've been riding for about a month, first 2 weeks were good with no issues.. then a couple days out of the week I'd start the bike and it would Rev up to about 5000-6000 rpms then drop down to 2000 and bounce from 1500 to 2000.. now it does it every time I start it up. Drives with no issues and doesn't seam to have a loss of power.ive replaced fuel filter, spark plugs and air filter and stil the idle bounces when I come to a stop or start up.
