So: just got off the phone with my mechanic. My 1988 GSXF400 has done its rings, and it looks liked $1300 or so to get it fixed (it needs a new back disc and a couple of other minor things too). I got it for $2500 and people are trying to sell them on Bikesales for up to 5 grand, so in some ways it might be worthwhile, but of course you then don't know what else might be wrong with it or go wrong. If it owed me $3800 or so it would be an expensive old bike and I'd never get all that back, but the other alternative is to sell it to a wrecker (likely for 50 bucks) and kiss my $2.5k goodbye. Because I'm a bit over-stretched financially at the moment I'd then have to get dealer finance to get another bike, and might even struggle a bit to get that. The latter would be nice: pick up something for 6 or 7 grand that's a hell of a lot newer and more reliable. After all, I commute every day on it, and have to, so a couple of weeks in the workshop just kills me. On the other hand, I really can't afford to blow a bunch of cash at this point, and nor do I want to borrow and get even more over-stretched. Apparently there aren't any replacement motors around to put in it either. So I guess my questions are about whether $1300 seems reasonable for a top-end rebuild, and about what you might do in my shoes.
