my 650 gives one loud back fire on the first start of the day, it only happens if bike sat over night, i hate it because it sounds like a gun shot and draws unwanted attention, if i pull the choke after the engine starts spinning up i can stop it from happening....sometimes, it always just one bang too and then it runs normally, the float levels are spot on and it idles perfect, anyone else have this issue
