mudslinger64 Posted November 28, 2004 Share Posted November 28, 2004 i have a chance to buy a wrecked 98 zr 600 efi with a newly rebuilt engine and was wondering if this would be an easy swap since the 580 engine needs a new cylinder and piston,i can get the 600 for less than it would cost to fix the 580 what would i have to do,just change the ecu and put the 600 in or what?thanks for any info Link to comment Share on other sites More sharing options...
letsfishjeff Posted November 28, 2004 Share Posted November 28, 2004 It can be done but its a LOT OF WORK! I just rebuilt my 600 from the crank on up for under 500.00! Thats new bearings on the crank seals pistons and boring of all three cylinders! Thats a good deal for a new engine! Link to comment Share on other sites More sharing options...
sledhead Posted November 28, 2004 Share Posted November 28, 2004 this will be to much work unless you can fix the zr 600 chassis. They have different wiring harness the way the engine sits in the chassis. The 97 ext is closed curcuit ingnition and the zr it open curcuit ignition. you would probably need to fab new motor mounts as well. they use different belts. I would opt for just fixing the 580 motor. Link to comment Share on other sites More sharing options...
mudslinger64 Posted November 28, 2004 Author Share Posted November 28, 2004 the 600 is a twin not the triple if that makes a difference. Link to comment Share on other sites More sharing options...
letsfishjeff Posted November 29, 2004 Share Posted November 29, 2004 Dont make really any differnce Still have to change wiring make motor mounts not to mention the clutching changes. If it is a twin probly cheaper for a rebuild. Or sell it for parts to rebuild the zr chassis. just my two cents!!! Link to comment Share on other sites More sharing options...
