1985 NH-80 multiple issues

[pfroh1]

I just recently got a NH-80 that was stores in an attic for 15 years. It was full of gas so I've had a mechanic friend of mine cleaning the whole fuel system. He did an acid bath on the tank then lined it with restore. It ran for about an hour then completly plugged up everything again. Since that epic run its been parked in the garage an has oil leaking bad which it never did before. It's running straight down the body and off the rear tire. My guy isn't familiar with scooters any suggestions of where I can tell him to look for oil leaks and or what to do different with the gas tank?

if its that far back, it may be the actual oil line from the tank may have been dislodged.
