I had an '86, loved the engine, had a Sudco 4-1 pipe, sounded freaking awesome, idled like a hot small block chevy and screamed at high rpm. Handling and braking was NOT as good as the engine, but it was still a great bike.
Taking the carbs apart is not too bad (V-4 Hondas are MUCH worse), you just need a large clean workspace (a big white towel on a table is perfect) to lay everything out on and be patient. I've done it a bunch of times, a friend still has an '85. They seem to be more sensitive to sitting than they used to be back in the day, I'd say it's the shitty ethanol fuel. Use stabilizer in the fuel if it's going to sit more than a few weeks. Seriously.
While the carbs are off take a really good look at all of the rubber carb and manifold boots, there's a lot of them and it's not cheap to replace all of them, we had to do it on my friends '85 a few years ago due to a lot of cracking and the resulting vacuum leaks.
