New to me 2007 King Quad LT-450AX

[abi]

Hello ladies and gents. Just picked this guy up in October and getting around to doing the required maintenance to make sure everything is right before any long rides or work is done. 

Some background: I am I believe the 4th owner, (however the 3rd didn't actually ride it). It has unknown hours or odometer due to what appears to be a common issue. 

I have noticed the fuel gauge doesn't work (just keeps flashing empty),

I did come across a google search that mentioned these were a common problem but was fixed by replacing the dash (seems like overkill) and another post mentioning someone attempting a fix. 

Any particular issues on these quads to pay attention to beyond the dash ?

Going to be replacing the rear tires, oil change, filters and plug. Anything else I should do with an unknown history such as diff flush/change ? 

I believe there is a service manual here but I need a few more posts. Hopefully this post will drive some answers and more questions I might have. Thanks!

IMO the kingquad is the most underrated and most reliable wheeler out there. You shouldnt have much for issues but definitely change all the fluids and change them at the very least, once a year.
