Hey guys I need all the help I can get. I'm doing my first full engine rebuild on my yamaha blaster I just put the 2 cases back together I have a few problems. First the crank doesn't spin and freely as it should and I've already tapped on both sides still the same what should I Do? Another problem I don't have pc high performance grease for the seals are there any other kind of grease I can use at the local auto part store? Last question is now I can not turn the sprocket to shift gears is that normal?
