gpz 900r

[farmer]

Would like to do a front and rear end swap on the 900. The front end swap is fairly straight forward but I am not so sure on the rear. The zzr1100 rear swingarm only pivots at the frame but the 900r uses the motor as well. is it a case of just cutting the middle section out and adding the right bushes and bearings ? . Any help would be great.

A tape measure is your friend , nothings Impossable if you throw enough time money and skinned knuckels at it. Might be a good idea to drop into the intro area and drop a little line as to your story before the sharks start to turn up. Questions are fine but people like a little courtesy around these parts. Info's free for people happy to say hi before asking the orical for input.

You will prob find the stock swing arm will take a wider rim/tyre package if you want an easyer way out. The later 900's were 150 tyre stock so a 180 or 190 will prob squeeze in on a correct rim. If you want some bling on your arm , what about a braced stock arm ?

Say a quick hello in here mate: http://www.streetfighters.com.au/forum/forumdisplay.php?39-Welcome-To-The-Madness

Welcome aboard.

This is what I read on the subject you are chasing:

"Use a ZZR1100C wheel for the rear and a GPZ500S(D) for the front. A 180 tyre will fit using the original swingarm."

I've never done it but maybe someone here can confirm this.

What model you got?? I have a 92 a8 and the fork legs are 41mm (the one with 17" front wheel)exactly the same as a zz600 so you can with heavier springs just lide the complete front end in to the original gpz triples - this will give you a fully adjustable front end with all rebound,compression and pre load. A zzr600 rear wheel will also fit straight in ,I had my zzr6 and the gpz side by side and it looks like a direct bolt in job you will then be able to rum a 170mm rear tire. I have just bought 2 more gpz's that will make 2 and 1/2 in my garage.

There is a thread on gpzzone.co.uk about how to do this swap, apparently the c model arm os the best one to use

[farmer]

Thanks. I have got a 1984 900 and when I compare it to my sons zzr600 the 600 has a wider swingarm so I would have to machine on of the bushes down a bit . I like the look of the 900 that pizz did and it look like he used a zzr rear. I am just trying to get a bit of info to make sure I do it the best way. I will check out the uk site . thanks.

[damo1]

You have to pay to use that site you can't view anything on iit.
As far as I'm aware the gpz swing arm was the same from start to
Finish I'm getting an a4 85 mod delivered on Friday ill check it against
The a8 91mod when I get it for you.
But the zzr into the a8 is a sure bolt in I spent hrs looking at them side
By side.

I have had a look at a thread on gpzzone about this swap and they recon that the zzr1100c is the one to use, there is a 16 page thread including the dimensions etc. I have tried to copy the pic and will post it here.

Hey no worries, I was looking on my computer and found some really good info on gpz900s that were downloaded from gpz900.org before it disappeared when big andy got cancer There is a lot of info on gusseting the frame fitting front and rear ends etc, if you and damo pm me your email addresses I will send them on to you?

[Hillsy]

Yep but if you have a look at it the pics are dead :(
Yeah - that weird. The pics on the first 2 pages are there then the rest are dead (?)

Any idea why Si? They're all ASF uploaded pics??

[ozzy1100]

Rons gpz and z1r are 2 of my all time fav bikes......

[damo1]

Evad did you get my PM??

[evad]

Hey Damo, got the first one with no email addy on it that I replied to but nothing after that.

[damo1]

O ok ill resend it.

Yep, I know exactly why, and it's the bane of this bloody forum. The old system of uploading your photos to the ASF server (which was ultimately the reason that we had to change because it was killing it) meant we had literally 1000s of photos in one folder. This folder was then backed up and saved ready for the new server. Once we moved I tried to upload the photos to the new server, but it got half way and then won't let me load any more, no matter what I do. Callan has also looked and can't explain it. Add to that the fact that the old photos has a URL of asfphotos.com and that no longer exists, so all the photos that used to be there now link to nothing, no only that, some fuckwit Spambot has managed to infiltrate that URL link and now some shop wiki bullshit shows up wherever there is a dead link. I can do nothing about either of the above problems and get asked at least twice a week about it. Can you see how frustrating that is? The only possible way to fix this is for the photos to be replaced, but a lot of guys have either lost the photos, can't be bothered or don't come here any more. It's a drag I can tell you.

[Hillsy]

No worries Si - I kinda thought it was to do with the forum changeover but some pics appearing and others not had me curious.
