2001 Polaris Scrambler 400L Getting Trail Ready

So I recently got a 2001 Scrambler 400 2x4. The guy before me claimed these things had been done to it:

Top end bored to 420, jug hot tanked and honed, Weisco piston
Oil injection delete (disconnected?)
FMF pipe
Hard wired fan (thermal switch broke?)


I have discovered a few things on the wheeler and wanted to make a post on here since I really cant find much anywhere else on these wheelers.
-First the rear shock is either blown or lost its nitrogen charge. Are these fox piggyback shocks easy to rebuild? Or should I look for other alternatives? Is there a way to try to recharge it?
-The front ball bushings are worn pretty bad (top of strut) and I think I am missing the rubber spacer for them, Should I just get the spacer and see if it tightens up?
-The tie rods were way worn, came with a new set so I have replaced those already
-Wheeler came without an airbox and a uni filter, as I hope to take this trail riding, I have ordered an OEM airbox to put on it.
-Exhaust pipe mount was broken off, I welded it back already so that shouldnt be an issue anymore.
-I have a small oil leak from somewhere, transmission seems to be culprit (low on oil) what oil do I use to replenish?
-Front wheels have 3 stripped lug nuts (i did not do it) so I cant take them off at the moment

It starts and runs and rides and boy is it wicked fast, really wanting to get this thing ready to trail ride in the spring. I would like to re-enable the oil injection if the pump is still there just for convenience and I never had issues with my blasters injection system. What is the best way to re-enable the oil injection system? And what is the best way to get to it with the engine still in the wheeler?

If anyone has any insight or experience working on this particular wheeler your input would be greatly appreciated!

If I need to post pictures of anything let me know and I will see what I can do.
