wow man, that bike sounds like an awesome find, besides the mileage its exactly what my bike was when i got it... for miles that low it sounds worth it, and what the other guys said, full service is the way to go. get some pics if you get the bike! once you get a bike like that serviced up and reliable, theyre solid, and more fun that you can beleive an 87 bike to be. i love mine, i ride mine year round basically, besides a few months of winter when the roads are icy and it gets down to -40 or so.
just cause i never get tired of posting them heres a before and after of my 87 hurricane
