I probably leave it alone. I got the bike its all original. Been in storage since 1984, in garage. It had the tires from 1983, 2800miles. I changed fluids, it started rt up. I put new tires plugs & needs fork seals. It has all paper work 1 owner. My friends brother bought it new & he past away & they GAVE it to me. I think he gave a little over $2400.00 for it new. I have the receipt. I get pictures on here if I figure out how
