I did a 97 Bubble back 2 years ago. A fair bit of work but not that hard to do. Almost every part is still available including all the decals. Carb was a bit off (bad rebuild?) but a QFT M600 last year took care of that. Still a few jobs to do (see PP Digital Pro display issues elsewhere) but that's half the fun!
Still to complete:
Searching for a Digital Pro PP display due old one fading out.
Getting fed up of straight through exhaust so looking for a 97 hull hugger muffler
Stereo Install
1 Tracking fin bent
Electrics need a bit more fiddling
Smell of fuel when turning - no sign of venting from tank so a complete mystery.
Brace removable rear floor panel which is spongy (bit of delamination in panel)
Wake, as suggested above, is exceptional.
