Ok so I purchased a 2016 c650 sport. Immaculate in appearance with 10400 miles about a month and a half ago. What do you know.Timing chain jumps and valves and pistons and cylinder casing they telling me needs to be replace at a cost of 4500 dollars. I just spent about 7400 with tax for the bike and added a 400 slip on. I asked the dealer to talk to BMW to see if they can help in any way. This is ridiculous. I'm pissed to say the least.
