Title: YZF vs. GSXR Rear Wheel swap
Post by: DB Cooper on October 19, 2011, 01:06:06 PM
Thanks for the info guys.
As I'm trying to source the parts needed for the 17" YZF rear wheel conversion as well, I'll have time to decide over the winter which shock I'll put on.

Anxious to hear what Randy is up to though......

Mark, keep us informed as to what Penske has to say.

Kevin,

Why are you going with the YZF rear?  The GSXR is so much easier and I'm going to bet that the parts are much more ready available.  Not to mention no machining necessary and the end result is the same, a 17"x5.5" rear wheel.

Just curious,

Hi CraigO.
I considered the GSXR conversion and may still do that if I can't source the YZF parts (and which ever is the cheapest option). The GSXR conversion requires the wheel, caliper and stay, master cylinder, and the brake line. It also requires welding if I want to keep the center stand, which I do. The YZF does require some machine shop time, but I have a buddy (an AME) that does this stuff in his spare time. The YZF conversion lets me keep all my rear OE brake components (I have the blue dots up front) which have recent pads, and I know that nothing is seized up. Either way I'll be happy just to go to radial tires.

Kevin,

No need to change the rear master cylinder with the GSXR conversion.  You also do not need to weld anything, just find an anchor point for the brake torque arm.

That said, you'll do what you want to do.

Kevin,

The GSXR wheel does not require welding.  Open the link below and download the attachment.

to be honest i was at first looking for the YZF600 rear wheel and forks before i did my FZ1 conversion..... couldnt find the yzf parts but i did have to push that wrecked FZ1 out of my way while i was looking and that;s what got me thinking.

i guess what i'm saying is to be open to different possibilities, you never know when something good can happen.


KOokaloo!

I guess this thread is now about the wheel swap.

Here is a link to the wheel you need.  Ask if he has the whole real wheel assy as well as the brake parts.  That's what I did and got everything for $150 plus shipping. 

Worth a shot???

Hey Craigo.
Sorry so slow to reply, didn't see it until now.
Anyways, I did see this ad on ebay, and another one as well. I sent queries to the sellers to see if they might have other parts as well,but I haven't heard back as of yet. Just today, I found a new local guy, http://www.rpm-cycle.com/ (http://www.rpm-cycle.com/)  who sells "used, late model sport bike parts", and he's only 20 minutes down the road from me! I called him, and he thinks he might have what I need, he's going to call me back on Monday.
If he does have the stuff, great. I can even inspect before I buy, and no shipping charges.
Again, thanks for the heads up on this mod, it's going to save some grief, time and money.
I owe you a beer or two!

Kevin, have a look at my pics here:

http://s398.photobucket.com/albums/pp62/billwest_perth/FJ1200/ (http://s398.photobucket.com/albums/pp62/billwest_perth/FJ1200/)

mainly the last 8 or so.

No underslung caliper, no welding, no loss of centre stand.

Mix of GSXR wheel, and Katana brake/torque arm.

Bill.

Hey Bill.
It never occured to me to put the caliper up top. It even looks like the OE FJ brake line will fit.
I'm still waiting on a local motorcycle salvage guy to get back to me to tell me if he has the parts I need, he says he's pretty sure he does.
I'm anxious to get the parts in my hands so I can start this project. What year is your bike Bill? Also, what size of tire do you run? Any clearance problems?
Thanks
Kevin

The GSXR wheel swap is so easy my mom could do it.You do need the brake line and for the spacers no problem getting them from a bike shop my 91 wheel didnt have them.Good luck and my bike has a Bridgestone batlac on it with about a 1/8 of clearence on chain.Wheel lucks great on the FJ.

Thanks Bill and Buddy for the extra pictures and stuff. This looks like it will be a painless swap.
I got a call back from the salvage guy, and he has all the parts I need except the sprocket carrier and cush rubbers, which I can source from ebay. The parts are from a 92, so the wheel will match the FJ's front wheel, I just have to paint it. The caliper he has is from a GSXR, so I will have to go with it mounted on the bottom of the swing arm, which means a longer brake line, but I wanted a braided line on the back anyways.
The fun begins. I'm really looking forward to a bigger choice in tires now.

Kevin,

This swap is really not that difficult.  The hardest part for me was holding the caliper holder, the spacer and the washer I used as a spacer while putting the FJ axel on the right side of the bike.  Other than that, not much different than removing your wheel to have the tire replaced.

Just watch out that you get the spacer that fits behind the sprocket carrier and the wheel.  That's real important to the strength and integrity of the wheel pack.

Sorry that I can not find any more pics of my wheel swap.

If any questions arise, just post, you are not alone,

CraigO

Post by: DB Cooper on October 28, 2011, 03:11:10 PM
Thanks CraigO. Yes, this looks pretty easy.  I was looking at the Parts diagram for the gsxr, and I know which spacer you mean. The salvage dude has the whole axle and spacer, I'm hoping it's the right one. I'll know tomorrow when I go to inspect the parts.
Thanks Kevin

 I received most of the parts I needed for the conversion today, but I still need the sprocket carrier and cush drive rubbers, but hopefully I should get those this week coming. The wheel is finished in BRIGHT red, and I'd like to match it to the front wheel FJ grey color, or maybe go to a satin black. Does anyone know if the factory color is painted or powder coated? It is possible to just, sand, prime and paint?
Thanks
Kevin

I'd guess that the factory powder coats the wheels.  However, that doesn't mean you can't just paint them.
I'd choose one of the "epoxy" paints to get a harder finish.

Thanks Arnie.
Thats kinda what I thought, but I wasn't sure. Now just to find the factory grey color on the wheels. Possibly looking at changing the wheel colors too. My FJ is an 88 with the white, red and grey, so I'm wondering what colors might look good.

Thanks
Kevin

Kevin,

Either grey, red, or black. 
White will only look good while its clean - 10 min later you'll have to clean them again.
My GSXR wheel was white when I installed in on my bike.  Looks much better now that its grey.
