Motorcycle Repair: 1996 Road King, harley road king, agas

Question
I just bought a 1996 Harley Road King with 4k original miles. I was wondering if I should have all the fluids drained and filled due to it not being ridden much or it is ok to just change the oil and wait until 10k to do major service. Also, are there any additives I should add to the gas to keep the fuel injectors clean?   Thank you for your help.

Answer
It sounds like its been sitting for a while, so yes, I would change them. You dont need to put anything in the tank, but if the bike has been sitting for a long time with old agas in it I would drain it and put in fresh
Good luck and happy riding
