Yeah I heard about never taking your bike in for work at the dealership. Always some problems gonna come and bite u in the ass afterwards. Well I haven't had my stands come in yet so I had to take the whole bike in to get the tires changed. Drop her off in the morning and picked her up later that afternoon. I knew something was off when I start taking her out of the lot and the rear brake ain't working. Luckily the front does. I pump the rear a few times and the pressure goes up so thinking hmm weird. So I drive home with no further problems. Stop at McD's to take a quick breather. Start the bike up again ,shift into first and I hear this clunk sound and the bike surges forward. I had the front brake on and the clutch lever fully in. Bike has never done this to me before. So I get her home and try again. Yup, there's the clunk and the surging forwards again. I got no idea why after a front and rear tire change I would be having these issues. Bike is a K8 with 13k on her.
