Hey guys, another newbie here. Sorry to say! I'll probably be asking a lot of stupid questions, so bear with me.
I just picked up an '83 GPz1100 with EFI. The odometer shows 2860 miles, thats right, less than 3k. This thing still has the original tires on it. The tag on the plate says it was last registered in '96. Soo.... anyway, I bought it from a kid who's stepdad bought it at an estate sale as it is right now, so he really knows nothing.
I brought it home (it looks like it might have spent some time outdoors) and started assessing the bike. The exhaust was off, the throttle bodies were set back, the valve cover had been just laying on the head. The bike came with a box 'o parts, which included a new head gasket... hmm... someone was taking the head off. Did a compression check-
90,90,120,60. Not good. I took the head off tonight and found that I can see light through a couple valves and one port has some significant rust. Obviously some of the valves are stuck. The crosshatch can still be seen in the cylinders, so I filled them with oil to see how bad the rings are and if they're stuck.
So I'll be asking questions about this bike. I know its old, but its still pretty cool. I'll try to post in appropriate sections.
