Front axle spacer questions

[djrashonal]

How wide are those fork bottoms where the axle goes through?

And are they symmetrical about the fork leg centerline?

They are both 2 5/8" wide and seem to be symmetrical.

can you snap a shot of your axle and spacers alone?

I'll have snapshots up tomorrow Am

this is the shot from the ebay auction i got it from

out of curiosity, have you tried using your GSXR axle and spacers? does everything fit bolted up that way?

i tried, but the large side of the gsxr axle wont fit through the larger side of the 999 fork

Have you tried mocking up the axle and spacer with out the wheel, and taking measurements (vs the width of the wheel bearings) to determine where the problem is?

It will not be 100% exact due to the fork legs not being settled properly, but may shed some light on which part is "REALLY" the problem.

2 5/8" is 66.7mm.
They're likely 66mm wide.

OEM Monster forks are ~44mm wide.

So, a spacer that's ~11mm shorter should work.

That'd put it at roughly 19mm.

Lots of ASSuming in the above.....

Thats a good idea, I'll hoist everything up and do a mock up without the wheel. First I'll measure where it ends now, and where it is without the wheel. then i should get a pretty good idea of what it should be.

Well Nick I'd prefer to leave your ASSuming out of the forks.....or is it the forks out of your ASS   

I'll have a better idea tomorrow but your rough numbers seem to make sense. Hopefully you're off by two mm and I can just use that 21mm spacer you've got so I dont have to pay somebody a ridiculous amount of money to mill this one down. Thanks for all the help everyone - the bike is coming together and I'm super excited to get back on the road!

i'm still dumbfounded.... my 999 forks went right on with my stock axle, spacers, and wheel.

[djrashonal]

just did the 999 fork swap on my s2r800.
the 999 rotors stock have an offset of 5mm. your monster has an offset of ZERO, unless you changed that when messing with your rotors. What this means is that you will need to either space your rotors 5mm further out from their current location in regards to the wheel, or space your calipers 5mm closer.
I chose to space the calipers IN, as the 5mm thick washers with a 2cm outer diameter, and 1cm inner diameter were easy to produce. I also chose to get longer (and fancier) caliper bolts, as i was not comfortable with amount of thread in the caliper with the stock bolts.

does this mean you did a 5mm thick spacer for each caliper? because i think that might be where my problem is. The spacers for me are on my wheel. so if i took those spacers out and spaced the calipers in, I should have the clearance for the axle and the calipers should line up right with the rotors.

I'll know more when i get a chance to get to the bike and mock up the axle without the wheel (prolly about 2-ish hours)

yes. between the caliper and the caliper mount on the fork-bottom i have installed a 5mm spacer. effectively, it's a 5mm thick washer. 2cm outer diameter, 1cm inner diameter, 5mm thick. Two on each side, one for each bolt. 316 stainless, but that's just because it was available.
it will move your calipers 5mm closer to the wheel.

i am unsure if rotor spacing affects axle spacing.

[djrashonal]

OK so I measured how far the axle was spaced with the wheel on and where it was spaced when correctly placed over the holes with the wheel off

Wheel on:                                         4mm protruding on the brake side and 10mm on the clutch side
Wheel off correctly placed over holes:  2.5mm protruding on the brake side and 12mm on the clutch side

this leads me to believe that I need 2-3mm to make everything line up. I don't know if I have any play with the fork legs, or if i tighten them down in place if the axle will shift or it applying pressure to the fork legs could cause damage.

This gallery is new pics as of late last night/this morning. I snapped a few pics of the wheel and which way I had it going. the side that says "Front wheel" on it with the Red Grease around the bearing is the side the was facing the brake side. The bearing on the other side is recessed a bit (seen in the Pictures) and is facing the clutch side. If I flip that around the axle will go in far enough and everything will line up, but if I do then my tire will be backwards. Is that how it's supposed to be? or is that recess made for the spacer?
