My question is how often do I have to adjust my chain? Besides the obvious loose chain how often are some of you adjusting your chain? I was getting onto a 65mph highway from a 50mph and I was in 6th gear and I down shifted into 5th and somehow it went into neutral and I hit the throttle hard to get onto the highway I must of not pushed down hard enough to engage it into 5th and the engine just screamed and then I tried to put into gear and my chain came off of both sprockets.The chain was so loose that I was able to put it back on to ride it up the ramp onto a pickup truck.The chain was just hanging on I know when I left my driveway there was no way that it was that loose,Im sure that would of heard it. The bike was serviced at 1100 miles and at time of incident it had 1800 miles on it.Went to adjust it when I got it home as per specs it goes from 1.5in. to super tight.Any ideas?
