Re: YZF 600 Rear Wheel Mod

[wakdady]

so....... has anyone raised the rear via dogbones? or is it alright the way it would be after this swap?
I only ask, and bring up this overabused topic, because i've read in some places that the overall diameter of the tire was smaller than the 16".

I moved this post out of the Files Section and into the appropriate section.  Don't ask questions in the Files Section. They won't get answered.

This same question has been asked and answered here: http://www.fjowners.com/index.php?topic=3024.0

Depends on the tire you use.  A 170/60R17 is a pinch shorter than a 150/80B16.  If you have the 89+ model, you can make your own dogbones and put the rear wherever you like.  Read what Pat linked.

I have a 95 YZF600R rear wheel with a 160/70r17 Bridgestone BT021 and have not modified my bog bones in any way. When the bike is on the center stand, I have about 1/8"-1/4" daylight between the tire and ground. Handling and ride is excellent. Mathematically, this tire will give you roughly .37" or 9.4 mm more in overall rear tire height(diameter) and 1.17" or 29.72mm more in circumference than the stock 150/80r16. This will take a few hundred RPM off at any given speed/gear combination, in other words take away a small amount of mechanical gear. I chose to stay with the stock sprocket sizes.

Yes, its an easy mod. The modern tires you can now mount should make it easy to drag hard parts. My 89 is over an inch higher in the back and the extra clearance is .......usefull. If your centerstand is worn or damaged you can add metal to the "up stop" area to gain extra clearance.

looks like i gotta rehash this one.... got the wheel, got most if not all the components. Now I need a chain. To which spec do i shop for a chain? does it need to be a special size? or would a normal FJ1200 kit work fine?

[Marsh White]

A regular FJ1200 chain will work just fine.  112 links if I remember correctly.  I just always order a 120 link chain and go from there.

[craigo]

On my 90, the stock sprockets are 17/40 with a 530 chain.  I think it's a 120 link chain.  Just a tip, don't use the clip style master link that comes with cheaper chains.  Get a riveted one and save yourself a problem.  Just MHO.

i typically just order kits so i dont have to worry about link count.
but with the YZF wheel the rear sprocket might be a problem.

[SlowOldGuy]

I am recalling a 110 link chain.  Most sources only carry the 120 link version and you have to cut it down to size.

The YZF hub takes the same sprocket as the FJs and most other Yamaha  bikes 600cc or above so what ever the FJ calls for chain length would not change. (unless you swapped swingarms at the same time)

[Arnie]

OEM stock chain for FJ's is 110 links of 530 chain.  This will fit from 17x39 to 17x41 sprockets.  I'm using a 18x42 set of sprockets and need 112 links.
As most of us have 'discovered' - buy the best O or X ring HEAVY DUTY 530 chain you can, the FJ eats cheap chains for breakfast.  The more expensive chains end up lasting way way longer.

18x38, on 110 links ...

[wakdady]

okay cool, and lastly... which rear sprocket do i use? or are they the same? Since i have to buy a new chain and front sprocket, the rear needs replaced as well.

[tqmx1]

Be it FJ FZ YZF the rear sprockets are all the same.
