Question 1981 YZ125 suspension

I'm looking at a 1981 YZ125 to use as a vintage race bike. It seems to run well and the price is good but the suspension seems to have no damping. My question is can I simply remove and flush out the old oil and replace it with new and have the shock recharged and expect good results or do I need a professional to rebuild it? I'm planning on racing the desert 100 in the 50 mile vintage class.

if your planning on racing get it rebuilt somewhere for your weight specifically or get an aftermarket shock....last thing you need is some rear end swap in a high speed whoop section from the stock shock...I know first hand....im sure works performance makes a decent aftermarket one......never skimp on suspension....
