Turning a KZ1000 J into a ELR ?

I have a 1981 KZ1000 J and would like to make a ELR bike.
Is it just a matter of finding the GPZ body parts?, will these bolt directly onto the J frame?

Its a possibility. Someone on here did that. A guy with his little girl that help...... Kane

pretty much...but you have to decide if you wish to recreate the commercially available 'R' model or the very rare 'S' model. Do a search on pictures of Eddie racing and you'll note he's riding with a J-style tank = that's the original S model...BUT, I have seen pictures of 'S' bikes with GPz-style tanks and J tanks....there have been many posts on this site dealing with ELR's:)

I have started searching for the body panels to convert my J into an ELR. man there are not many GPZ1100 parts laying around these days.
It looks like the side covers of the GPZ are a little larger than the original KZ1000 J covers. Can anyone confirm this? Thanks,

Side covers for KZ1000J1/2/3 = KZ1000R1/2 = KZ1100R1 = KZ1100B1/2...same for the basic shape of the tail fairing...remember, if you opt for using the GPz1100B1 (1981) tank as the basis for your ELR clone (same shape as the 1982/3 ELR tank), you must locate a round fuel gauge (same as the 1981 KZ1000J1). 1982 on uses the oblong fuel gauge.
