Thanks Maintain. And everyone else for your inputs.
I do have 3.73 gears according to the tag BUT it looks like someone has been in there doing something. There is gasket sealer smushed out around the rim, and it is not "sealing" very well either.
What is a common upgrade or change aorund in there? It is not typical for anything in there to break is it? Just wondering why it would look like someone did work in there.
If I am running at 70 my RPM's are a little over 2K. I mean like half of a marking on the stock gauge cluster. So, I would guess that is about 2150 or so.
