GPZ1100 Frankinbike is close to finished

aquaholic wrote: Hello there, I am doing a rebuild on a 1981 KZ1000 J2 and was curious about the wide tires from the Honda. Did you have to do any modifications to the swing arm to get the clearance for the wider tire ? Drop me a line when you have a minute please. And i have to say that is one very sharp Frankin' Bike. Excellent job. Be well and thanks in advance.

Hi, thanks glad to help with your inquiry, The honda wheels were from a 2006 CBR1000F the rear is a 170 x 17 and it was a challenge. The only reason I Persisted was because I got both wheels for a good price. If I had to do this again I'd look at other wheels. The axle had to be specially shortened and rethreaded. The brake disc was from a CB750 to suite the GPZ900R caliper.

The rear sprocket hub stuck out a long way and to make it central took a bit of machining, lucky for me a had a friend with a workshop.
The swingarm was already on the frame when I bought it, I believe it was from a later GPZ900 or 750R, again I got this for a good price so I can't really comment much about whether any or much modification was required.

The front wheel wasn't much of a problem but did require new/ old spacers made to fit. It does not have a speedo drive but I have a GPS speed which does not require a drive.

I will be happy to help if you still want to go ahead but if I was to do this again I'd find another set of wheels maybe GSXR750/1000.

Let me know (PM me) if you have other questions. I'm not at home presently so don't expect a quick response.

New guy here, love the build, just picked up a Kz1100 frankebike project, I'm new to KZ's, was wondering what the seat and tail piece came off?

That's the stock GPz tail piece. Also found on the GPz750, KZ700, Kz750L & KZ1000R (ELR).

Thanks, that is one of a few ways I'm looking on going with mine, another seat and tail I'm considering is from The Honda CB 750/900/1100f.

Why on earth would you do that..? The Kawasaki seat and tail suit the bike, leave the Honda stuff on the Honda, I've owned both and really, the body work is very similar, I don't get it, much easier to use whats meant to be there..?

Joe, from my point of view the GPZ1100 seat and tail piece look great, if there was a mistake on my bike it would be that I didn't match the seat to the tail piece and the tank when I had it re-upholstered, so I had gaps in places. Also when the new cover was put on the plastic seat base appears to have been distorted slightly (maybe from the staples??).
