What to do first?

[FJmonkey]

I did the rear wheel mod using a 92' GSXR 750 wheel. Super easy mod. Basically as easy as a simple wheel removal and install. Add two 4mm thick 20mm inside dia. washers and decide where to mount the forward attach point of the caliper support arm.

I did the same (92' 750 GSXR, in Periwinkle) on my 86', easy bolt on mod. I added a mount point on the swing arm for the under-slung brake, other than that, just spacers and a nice fat rear tire.

Yes, i have thought about the GSXR change. It seems easy and straightforward as you say.
Thought i might do the rear wheel conversion next winter
Will spend this summer gathering parts for the rear..

Thanks for the tip on the washers, did not know about them

As i mentioned in my last post, i had the wrong rim for the front conversion. I solved it by buying a 91 fzr1000 front wheel on ebay.
Total cost with shipment to Norway $116.. That's cheap compare to $450 that it would cost me home in Norway!!

Thought i seemed a bit to cheap but i have bought topp stuff from him before.
The rim had been cromed which has started to peel of. But since I'm having it sandblasted before paint it really does not matter.

Well, i only thought i would start with something small and simple when i started modding.. Well... I was wrong. This is an addiction

Ken, just curious, what's your plan on adapting the 17mm bearings used in the FZR rim, to your 15mm axle?

[andyb]

Okey, I just figured out that I have been slopy, and the rim i bought was not an FZR1000, but an FZR600 rim! I have not yet checked the difference, but i pretty sure the 600 is 3" and 3,5"..
I might have used the 600'n, but since i recently order a new tyre and all i might ass well sell the 600 rim.

A 1990 FZR600 should have a 3.0" wheel.  Not sure on the other years, but a quick look suggests that they'd be 3.0 width until the big redesign that showed up in 1994.  A magazine test from the era says that the 94 model had "new wider wheels" but failed to say exactly what sizes they went to or started from.

Carry on.

Not sure i undersans your question, but would that mean that the 91 fzr rim would need an axel to big for my 89 forks? I thought the 91 fzr1000 rim were simiar to the 87/88 fzr1000 rim..
Hmm if that isen't the case, i haven't got my facts right and i would be stuck with another unusable rim

Not sure i undersans your question, but would that mean hat the 91 fzr rim would need an axel to big for my 89 forks?

The FZR 1000 87/88 front had 15mm axial, after that they went up to a thicker 17mm axial. If only they made the right size bearings to fit the newer wheels to the 15mm axial.

Thanks, i would try to se if the seller would let me change the rim to an earlier model..
By the way, anyone know the size of the 91' FZR1000 forks and can comfirm it? If ive got my facts right this time they are 43mm? To upgrade to those forks would mean replacing more then just forks..?

Cheers

The '91-'93 FZR1000 forks are upside down forks with 17mm axle (I have on my '84 see pictures)
The '89 and '90 FZR1000 forks are conventional with 43mm stanchion tubes and 17mm axle (FJ is 41mm)
The '87 and '88 FZR1000 rim uses a 15mm axle.

We have been telling you to get a 87/88 FZR rim for a reason.

Well, I'll get there, eventually. FZR rims in general is easy to find, 87/88 not so easy  

It could be fun to replace forks as well, but that's for another time

Before i make a fool out of my self (maybe too late:-) i would guess this rim would fit?

Not sure if my info will be any help, , I bought what was supposed to be an 87/88 fzr1000 front rim, turned out to be an fz1 rim , that takes a 22mm axle, no luck with bearings, so had 2 steel shims made so I could use my 15mm axle and all is good , some here have shimmed 15>17mm without problems

Thanks for the tip.
It seems like i manager to track down one of the few 87/88 rims on ebay, hopefully
I was able to cancel my order on the 91 rim, luckily..

I recently bumped into this site, anyone been there before?
http://www.fjcatalogue.com/catalog/item/7303420/8542647.htm

I was searching more info regarding rear wheel conversion on the FJ.
Looks like on this site you can buy all the parts you need for the FZR conversion. You would only need to add either a 17" nor a 18" FZR 87/88 wheel.

Phil Hacker has been developing and testing mods to FJ's for many many years and knows what works and what does not.

If Phil is selling it as a kit then it will work and work well.

Just be aware that to purchase from Phil you need to join the UK FJ owners club.

I used to be a member but for personal reasons I decided to let it lapse.

Looks like a good wheel mate

Looks like a good wheel mate 

Yes i thought so too. But i can't decide which size i should go for.
I am planning next winters project, and rear wheel conversions is one of them.
Not surev it will end up with the FZR, but will give it some thoughts.
Guys, any thoughts to what's most desirable of 17" and 18"?

Cheers
