So I had my starter for my R90/6 rebuilt May of 2006 and it seemed like a great fix. Fall of 2009, it became really hard to start. It even smoked a bit one day when I was trying to get it started. Battery is about 4 years old but it is usually charged enought to kick over the bike. I pulled off the top of the motor and the airfilter covers to look at it to see if there was a loose connection. did not see anything. I did not pull off the front cover too look. Should I be worried that it is time for another rebuild already? How long do starters last? I have stood there drinking alot of beer looking at it...........and I am all out of ideas.
