I owned one and my dad owned two.
His first was an 85 that was ported by ginder and ran like a top. We were in northern canada and found a 92 pinky from a dealer who wanted to ditch it. 1200 us at the time. That pinkey was great.
Mine was an 86 with piston slap and a fox rear shock. I only lubed the swing arm and rode the bike. That thing just ran and ran and ran.... I will post a pic later on.
