YZF600R wheel mod wrap up...... or why I'm not a dive bomber pilot

Say, Fred,

Are you still running that uncut stock brake stay arm?

How much clearance between it and the 170? (Sure looks tight in the pic!)

I should have mentioned... I haven't been able to find a number for the amount the stay arm needs to get spaced out anywhere. I'm putting on a 5.5 in. and I figured that if you'd found that clearance to be acceptable with your 170, then likely 5mm would be enough for a 180 (180 - 170)/2. And if you were getting rubbing, then I'd have to go a bit farther...

TIA, and cheers!

It is tight, but no rubbing. I wasn't able to find any measurements for the stay either which led to my problem. It might work with a 180 tire but I have my doubts. Just giving it an eyeball measurement it looks like about 5mm clearance with the 170. I'll check it later but I don't have a caliper or anything to measure it .

Thanks, Fred,

The way I see it, as long as there's some clearance at the most extreme condition, it's enough... no extra points for a bigger-than-necessary gap! 

Cheers!

It's been a while, but IIRC, Jon Cain told me 8mm.

Hey Steve,
I measured the clearance of the stay today. I came up with 5.5 mm between the tire and the stay. I used stacked valve shims to measure it, so there is probably a couple hundredths more space in there. The stacked shims were tight enough that there was no wobble, but loose enough that they would fall out if I let them go.

Thanks, Fred, that's certainly close enough!

Here are a couple of your pics:





I think that is the most "fairing modified" FJ I've ever seen that is still utilizing the stock frame.  Your camera SUCKS though!!!  I'd like to see some clearer images sometime if you have them.  Nice front and rear end mods as well!

....... Thanks March, ....Yes, I used one of those trow-away-camera's.

Fred,
Thanks for that post on the rear wheel mod. I have been inspired. I've owned FJ's since I bought my first new one in 84. At the time there were choices for rubber, but now only Avon makes radials in 16 inch. By the way, I bought those Avons cause I was going to ride an 86 one more season, so I didn't want to fork over too much coin for tires to give to the next owner. I have to say that those tires exceeded my expectations, over Metzlers and Bridgestone. I degress.

I just wanted to get some clairification on the milling part for the 17" conversion. On AK's site it says "The way it goes is 8mm off of either side and 3mm off of the sprocket carrier on the outside where the sprocket bolts up". I just can't interpret the "8mm of either side" What does that mean exactly? 8mm of the cush drive or the chain tensioners? I'm trying to hunt down a wheel, but can't find any here in Canada. What's a good price for a wheel? Also would it be alright to do this mod and keep the 16" front?

I'm also looking into doing the calipers from the earlier R1-R6 and the master from the ZRX1100 or 12. I need the holes for the mirrors on the 84. But again finding parts locally is futile. Has anyone ever dealt with GDL Cycle Sports in Florida? I find the site odd, that there is no contact info or order form. Great prices for calipers though, $50.00 ea.

As you said Fed, this is a GREAT!!! site with GREAT people!!! Been learning lots reading here. Just one more mod, I'm doing the headlight relay setup. The biggest issue I'm having with that is finding wire, found all the other parts in one store (no wires). Most places sell spools of 100 ft. Can't find a place that sells it by the foot. More hunting today.   

Thanks again to everyone on the forum!

Try NAPA Auto Parts.

They usually have a pretty good selection, sold by the foot.

I found erverything today other than the Black lead. That shouldn't be too difficult:Ithink?

You can use a mid 90's YZF-600 rear wheel pre R-6 with all the stock axle spacers for that wheel and sprocket carrier.  You will also need the rear brake caliper mounting bracket. Remove 8mm off of the round axle spacer (making it shorter) on the sprocket side of the wheel. Remove 8mm off of the outer side of the brake caliper bracket (where it makes contact with the swingarm). Remove the sprocket studs from the sprocket carrier and turn 3mm off of the rear sprocket carrier where the sprocket sits. You will need to bend your brake stay just a bit to get it to line up with the newly machined brake caliper bracket and your good to go. With this wheel mod you will be able to run a 170-17 rear tire.  Hope this helps..

 As for the measurements.....Yeah what Eric said. I paid 50 bucks for my wheel on eBay, got the seller to throw in the rotor and caliper bracket too. But I lost a lot of auctions before I got that deal.
