Okay 650skull I thought that too and I looked up some stuff and decided to used marvel mystery oil to dump in, just because alot of things I read everyone said that's what they like best for it and it's not thick and black like oil. I did put the plugs back in afterwards and let it sit a bit, then tried to kick it.was locked up for a bit. Smoother now though, thinking maybe it was all crud filled and I think maybe poured in a bit too much ha. Should I still do that team, with it kicking better? My carbs are so freaking clean on a side note just waiting for the kit in the mail to build it back together.
