Hello everyone, this is my first post as I just took ownership of a severely abused 04 V. when i got it i was aware it had wiped the front cam, after changing that one, i was going over my work and noticed loose bolts in the rear cyl. area, further inspection revealed a wiped cam in the rear also. changed that one, replaced oil sending unit, and added a mechanical oil pressure gauge. Spinning over the engine with the starter does not register any pressure on the gauge. My question is should it? If so how much? any help or reply is much appriciated as I have a long automotive/mechanical background but this is my first atv/motorcycle. they are very different from what I'm used to.
