TechSmurf Posted June 5, 2005 Share Posted June 5, 2005 Recently acquired an '87 FZ600 from a friend after the engine went on him and he upgraded rather than rebuild it. I'd like to get the bike running again, but I've got a feeling the internal damage may make repair of the existing engine prohibative (no solid evidence yet, haven't started diagnostics). In preparation for the worst, though, I'm trying to find out what options I have for replacement of the existing engine... particularly if anything other than the 86-88 FZ engine will bolt in, or can be made to bolt in without excessive hassle (Radian? XJ? FZR with some work?). Also looking for any sites or other forums that would help support an FZ600. Any info/help is appreciated Link to comment Share on other sites More sharing options...
jixaw Posted June 17, 2005 Share Posted June 17, 2005 I have an FZ600...the XJ's engine is the same...you will have to use the FZ's carbs though... where are you located?... Link to comment Share on other sites More sharing options...
TechSmurf Posted July 5, 2005 Author Share Posted July 5, 2005 Southeast Arizona... Got the engine torn down and discovered the #3 piston and intake valve are now a 1-piece assembly, so the worst case scenario has been realized... any ideas are still more than welcome Link to comment Share on other sites More sharing options...
TechSmurf Posted July 9, 2005 Author Share Posted July 9, 2005 Well, so far the FZ600, YX600, XJ600 seem to have the only suitable chain-drive engines available... the XJ750 and XJ900 use the same basic air-cooled engine, but unfortunately are shaft drive... still trying to find other bikes that use this engine, but it's not looking promising.

Moderator YamaHead Posted July 9, 2005 Moderator Share Posted July 9, 2005 Not that it's much difference......but there's also the FJ600 (more common in the US ), but as said previously.......you'll have to use the 30mm carbs from the FZ, 'cause the 32mm carbs on an FJ won't fit between the frame rails on the FZ Link to comment Share on other sites More sharing options...

jixaw Posted July 14, 2005 Share Posted July 14, 2005 Wont FZ700 carbs work with the 600 motors?? Link to comment Share on other sites More sharing options...
Mike26 Posted July 15, 2005 Share Posted July 15, 2005 Wont FZ700 carbs work with the 600 motors?? ← Yes they work fine as they are the same base carb with a slightly larger bore Link to comment Share on other sites More sharing options...
