Im glad you said "Is that all you changed"... Went back out and looked at the bike. I found the wire from kickstand safety switch disconnected. Looks like the other end us under the upper neck covers with the reflectors. Gonna have to wait for daylight. Lets hope...If that’s all you changed they may just be too tight. When I installed mine I tightened then too much at first and as soon as the engine warmed it stalled.
