They will not affect the center stand not being level, just the rear wheel position at rest.
are the bones stock?another thing.the abs light is flashing.i know the back brakes are soft and i was going to bleed them but the nipple head is rung.what size nipple tread do i need? m6,m7,m8,m10???

Skik,

Yeah, those straight-plate "dogbones" are not stock.  That is why the rear end is so high in the air.  Nothing is wrong with the center stand, except now it is too short.  The correct length of dogbones will probably "fix" the center stand issue for you.

P.S. Life is too short, and health is too valuable, to ride on cheap parade-duty tires.

If you want to keep the ride hight you can add some extra material to the top edge of the centerstand to prevent it from rotating so far over center. I have TIG welded and ground my stand to get it just right.

Wouldn't it be better to add extra to the bottom? The amount it goes over centre is what stops it falling off the stand. I would not like to have the bike rocking off the stand with any less encouragement than it takes now and the height gain is negligible.

The best fix would be to reduce the rear end height, it looks way too high.

No, the centerstand on my 89 needed the extra material by the time it had 40,000 miles. There is lots of slop in the pivot holes, pivot bolts and the top edge of the stand that acts as the stop in the up position wares quickly.  I raised the rear almost 1 full inch and I've never had any problems with it rocking off the stand.

Another "fix" is to simply lay a short section of 2x4 under the stand when you use it. 

Raising the rear by shortening the dog bones can really help improve the handling of FJs.  If you change the dog bones to "fix" the center stand you probably won't like how the bike handles then...

Of course the middle ground is to make another set of dog bones slightly longer than the current ones so the rear wheel is just off the ground when on the center stand.

I had mine raised up pretty high in the rear at one time and it will effect the handling.  I since have lowered mine closer to the stock height, about 20 mm higher and am happy with the way it handles now.  I have a rear rack and large top box usually with some misc. stuff in it so it settles with me on it at a good balance point.

You can make those dog bones easily with some flat bar and a 12mm drill bit. If you do,  there are some design considerations.  The weak point is around the bolt hole area, notable the side area.  Use as wide a flat bar as you can fit.  Good practice to round all the sharp edges and to paint or coat them as best you can.

Your side stand as is probably short now also unless the P.O. modded it.

thanks for all the tips folks.im glad its just the bog bones.was starting to think the frame might be twisted or something else bad.the bike handles well [smooth] .wonder if i could stick some hard rubber onto the bottom of the stands?

My 89 does exactly the same thing (both wheels just touching the ground on the main stand), I have the RPM shock on the back set to the correct preload, my fork are 1/4" for slightly faster steering. I don't have any mods to the bones so I just put the stand on a wooden board when oiling the chain etc. The bike handles/ rides fantastic so I'll be damned if I'm touching the current ride height.
Why don't you go on the road, light up the rear tyre until the tread disappears and presto - clearance  :sarcastic: :good2:
