F3 wheel conversion question

My bike is basically ready to be ridden. That is If I could just wheelie everywhere. When I got the front wheel off eBay, it only came with the wheel and rotors. So my question is: which F3 spacer do I need to order right, or left (or that anyone might have to donate) What else do I need to expect to finish this project? I need some of you seasoned veterans' advice.

Or possibly the specs for the spacer you used. I can just purchase something similar and have it machined to specs. Since I live 2k miles away from civilization I'd rather not wait 2 more weeks before I can ride again

I can't remember exactly. But i ended up ordering an F3 axle with spacers off of eBay. I just mixed and matched until I got the correct spacing.

Hope Helimech doesn't mind. But he sent this to me in a PM awhile back when I asked about his F3 set up. Hopefully it helps you out.

The 900rr rear is a 100% bolt on swap. All the 919 stuff installs and away you go. That parts is easy.

The F3 front is a bit more challenging. You will need the F3 axle spacers & some spacers for the calipers.

Use the F3 axle spacers in conjunction with one of the 919 ale spacers, on the 919 axle to get the wheel centered up between the fork legs.

Next you will have to mock up your calipers and shim them with spacers to get them centered over the F3 rotors. I am using CBR954RR calipers and had to shim the L/H side 3.45mm and the right 4.15mm, you can use some stainless washers or have some spacers turned on a lathe.

Here is a pic from another WT thread of the spacer setup to get you started.

I machined my own space from a spare 919 one. I think I shaved it down to .045 inches and it worked fine.

Did you mean 0.45"? Because .045 is almost nothing!?

I would like to toss in another question: Why doesn't the f3 rear fit a 9er? How much work would be required?

It is a 5" and the 919/900 rear is a 5.50" .... or something like that. It's narrower and will require a smaller profile tire, also the sprocket might not line up. It pretty much just won't work at all.

Ha well crap, I had hope because the f3 I bought has a 180/55 17 on it. Just kept looking back and forth at it and the 9er's wondering.

This isn't to say I still won't try just once

Kicking this back up again.

I hope to be joining the 6 spoke club soon. I have the front wheel and rotor, now I need the spacers. Are there any that someone has laying around? Links to somewhere they purchased the spacers/axles?

Any help is greatly appreciated.

Here is a picture of my front axle setup to run a F3 front wheel on a 919. You may have to adjust the caliper spacer thickness depending on your forks, I was using F4i forks at the time.

All right. I'm using the stock 919 forks. I have an F3 front wheel with rotors. I was hoping to re-use the rotors with my existing 919 calipers. I guess all I need are some F3 spacers for the calipers. Yeah?

All you need is one F3 axle spacer & a few washers to make spacers for the calipers. You have everything else needed.

I used a rear axle washer along with a VFR spacer on my front. Didn't like how the wheel wasn't center.
Put the washer on the right side, had to sand it a little to get the wheel perfectly centered. That way I could use the same size spacers on the right and left calipers. Also bought longer caliper bolts, didn't trust having that much less thread in calipers.

Where did you buy longer bolts? Just hardware store bolts? What length did you end up with?
