REAR WHEEL MODS

[bama1]

Guys I was wondering with some of the rear wheel mods you can do on the FJ has anybody checked to see if the front sprocket Frank Moore used on his FJ to line up the chain would cut out some of the machine work on some of the mods.I know he used a VF1000 sprocket on his bike.I was just wondering if anybody has thought about that.I know the YZF600 plus the FZR1000 EXUP takes machine work on the sprocket carrier.
JUST WONDERING

I used the FZR1000 rim, it gives you a wider rim as well as a wider tread patch on the ground.  I had to have the countersprocket machined, we used a Honda 929? sprocket and machined it to fit.  I also had the countersprocket cover machine to clear the new chain and sprocket set up.

I am not sure you need to do any machine work on the countersprocket to get the YZF600 on the rear of these bikes.  But someone else should be able to clear it up for you.

If you are interested in having the rear FZR1000 rim set up on your bike let me know.  I know of a shop that does the work and you only need to send is your countersprocket cover, hub, brake stay, and brake stay arm.  They put all new bearings in the hub, machine it, and the other parts that need to be machined, make you a new set of dog bones (89-up) and will sell you a chain and new rear sprocket as well.  I had all this work done, including a new chain and rear sprocket and my total bill was about $600 including shipping.  May seem like a lot, and you will be closer to $1000 if you put on new tires and brake pads.  But the overall improvement in the bikes performance is phenomenal.

Anyways, I don't think you can avoid the sprocket and cover machine work if you want to run a 180 on the back of the FJ.

I wasn't talking about my bike doing the mod to I was just wondering if using the front VF1000 sprocket may cut out some machine work.I'm sure other people have thought about that.

[higbonzo]

I would have to read his post again, but I thought they machined the VF1000 sprocket on one side because it protuded on each side.

Frank Moores FZ1 rear swingarm and wheel swap he does have to take off one side of a lip on the front sprocket and once he did that everything lined up.I was just thinking if someone knew how much the VF1000 front sprocket moved out to maybe it would help on some of the other rear wheel mods.Maybe cut down on some of the machine work.

The modified VF1000R sprocket moves the chain out 2mm

No, the YZF600 wheel (17x5) requires no machining on the sprockets at all.  It's one of the best solutions for wheel swaps, but only allows a 170 or 160 tire.

Is it necessary to also change the swingarm to use the 5.5" FZR1000 wheel?

No

Thanks.

It seems that the 3.5/5.5 setup is the hot combination. I understand about the VFR1000 c/s sprocket, but it occurred to me that since apparently it's only spacing the chain out 2mm, might it not be possible to just put washers on the c/s cover bolts and thus avoid that bit of machining?

The use of the Honda sprocket WITH the FZ1 swingarm does not require any mods to the sprocket cover........
I'm not sure if we are all talking the same apples here?

uhhhhhhh that aint gonna work.... the problem is you cannot get the lockwasher and nut on the output shaft using the honda c/s sprocket without grinding the outside shoulder off the sprocket first.... the output shaft is just too short.

this can be fixed by splitting the case and installing a XJR 1300 output shaft which is the correct length for a 5.5" wide wheel and will allow use of stock sprockets.

your choice.....

kookAloo!

KOokaloo!

Sorry, I wasn't clear. I was referring to the machining of the c/s sprocket COVER that Higbonzo mentioned. Yes, I understand about grinding down the outer shoulder of the Honda sprocket.

And Harvy,

I was asking about using the 5.5" wheel with the stock swingarm.

[Harvy]

Cool Steve.....just trying to keep my ducks in order.

still wont work.... the clutch slave mounts to the c/s cover....but of course you could always fab a new longer clutch pushrod..... anything is possible if you want it badly enough.


Kookaloo!
