My 2009 RS SE 5 has developed a problem. It has a bit over 25,000 miles. I was riding and stopped for a short time. When I restarted it and put it in 1st, it made a grinding noise and did not want to go. Then it just took off. When first starting out, it stumbled and made the grinding noise, then took off. Going to get it on a trailer and to the dealer in the next few days. Oil level is full, when checking according to the manual procedure. I got it home. The next day I started it, and it worked fine, until it warmed up, then did the same thing. Oil was changed, by the dealer about 500 miles ago, and they installed a new battery last week. Everything checked out fine then. When I purchased it, last October, the dealer, I purchased it from said they had put in a new clutch. (21,000 miles on at that time)I am very careful to keep RPM above 4000, around town, and cruise a around 5000 when on the highway. Which in 4th gives me between 55 and 60 mph. It pull strongly going up hills.
