So I know when we start the bike cold it idles high for a few minutes. Mine does this and it usually seems normal. However today I started the bike as normal went for a 20 minute ride and had breakfast. When I started the bike to come home after around 30 minutes it started to idle high like usual but got a little crazy. I don't have a tach but when I was driving it would hardly even shift I could go around 25 mph without any throttle. Any ideas?
