Aright guys..... I've been riding my Murray around for a while since my build and a while back I started it up and let it worsen up. Walked away...... and heard the motor stopped running. So a OH CRAP was in order, found the bike had fallen over on its side and shut off. Upon seeing that, I pulled it back up and started it. Ran good then the side cover bolts had came loose. NOT GOOD, so I tore it back down , reinstalled a new gasket and put everything back in its place. And re-set valve lash at .003 on both sides, I've started it twice since then and it smokes a lot during warm up and then clears out after a few minutes....... So what has happen??????? Not sure so I need help from the group for assistance. Thanks!!
