I have a 2009 Suzuki Boulevard M90. Been running great, with little to now problems since I bought it new.
The other day as I was riding, a large "clunk" happened. It felt like it was on the left side, down by my feet. Almost felt like my kick stand came out and smacked at my boot. It has been happening more and more and always feels like a hard kick from the bike. Always on the left side. It kind of feels like a gear issue as I am usually sure I know what gear I am in, but have been getting much more confused since this has started (i.e., down shifting taking an extra or less shifts to get to 1).
Bike is shaft driven, and does not have a chain.
I took it for a quick ride this morning to see if I could identify anything more. When I pulled up to a parking space and tried to walk it backwards (in 1st and running), it wouldn't let me. After 2 or 3 times throttling forward and trying to go back again it finally let me.
