Hey there - got this R1 a few months ago and it runs and rides like a dream. Purchased with 5300 miles, around 6900 now. Only issue ever since I've gotten it, has been a rough start. Its gotten a little better since though. I've seen people say that these starters are practically disposable, could this be the issue? Fresh gas and fresh battery, measuring a bit over 12 volts. Anyone see this issue in the past?
