So..... If you are willing to get your hands dirty, the bike is fix-able. The engine has been made for 20+ years so parts are out there.
If you aren't willing to get your hands dirty, then it is not cost effective to fix. Could be a $2000 repair bill if you figure in the labor. Maybe more.
I bought my '01 on eBay for $500 with the engine in pieces and a melted piston & bad head (cam journal worn bad). I have a friend (now really good friend
) that is a machinist / rider that did the cylinder work for free. Around $600 in parts ($200 for a complete used head asembly) and I have a great bike.
Only issue I had was the engine was in pieces in boxes. I had to figure out where everything went. Otherwise, the engine is easy to work on.
The factory manual is slightly better for engine rebuilding, the Clymer's is better for everything else. I have both
. If you choose to repair it, You will definitely need a manual.
