1980 XS11 Special - Ugly Duckling Rebuild

[motoman]

Hi, Kurt -

The tire balancing product DiverRay referred to is called Ride-On ...

You can read about it here:

Ride-On Motorcycle Dynamic Balancer & Tire Sealant

If you're doing your own tire changes, you can purchase the product directly from Ride-On, or buy it elsewhere online, i.e. Amazon, etc.

If you're having it done, I doubt you'll have any trouble finding a tire shop/dealership in Atlanta that uses Ride-On ...

Like I previously stated, most all bike shops/dealerships use weight balancing as a SECONDARY option. Ride-On IS the go-to PRIMARY balancing method....least is in my part of country, everywhere. Plus you have flat protection using it. And, NO, it has no corrolation with the old green slime crap. No need to order, as you can buy it at most any local bike shop if your mounting your own tires. 8oz. bottle, you squeeze 4oz. thru valve stem in each wheel, air it up, DONE!

If the sizes of these bearings is mentioned I can 100% guarantee I can find every roller or needle bearing for these wheels (and the bike for the that matter) available in the U.S.A. I work for a Japanese production facility as Maintenance Manager and we replace dozens of bearings every week. I did not remove mine as I was sure I would destroy them on the way out. Without replacements in my hands that would not have been good. If I had the O.D. x I.D. x Width & Style (seal(s), shield, etc.) I am certain either McMaster-Carr or B&D Industrial will have them. If not, I have a dozen other places I can get them from or import them from Japan with one of my other orders if necessary. I will find them and post the results with contact info in an appropriate thread.

Hey Kurt,

Take a look at this rear bearing repair thread. Lots of pictures as well.

http://www.xs11.com/xs11-info/tech-t...pictorial.html

Here's a little quote from it telling what it's model # and dimensions are.

Drive side should be 5904 (one off size made ONLY for Yamaha about £45+vat) OR I use 2x6904 about £3( same bore and OD but only 9mm thick) so you will need a spacer made(37mm OD, 25mm ID, 5mm Thick) and place BETWEEN the 6904's when you reassemble.

SO...IF you can find a USA provider for this special bearing, you'll make many XS11 owners very happy!!!

XS Folks,

Thanks for info on "Ride-On". Obviously, I'd never heard of this product before. I grabbed the following text from their web-site:

"The great thing is Ride-On will continue to adjust and literally rebalance your tires as you ride for the legal life of the tires. So go ahead, pop off those wheel weights, shine your wheels, and enjoy the smoothest ride you have ever experienced on your bike thanks to the orange wonder of the world!"

I'm ASSUMING this stuff stays in a liquid form within the tire? My only concern would be that I install the new tires but I really won't be able to do any significant riding for a while until all the motor work is all done. Would that be a problem? It sounds like (from the snipped text above) that won't be a concern?

I kinda remember the green slime people use to use to seal punctures and damage. If I recall correctly you had to get the wheel spinning pretty quick once installed, the stuff WOULD harden up, make the wheels out-of-balance, AND totally screw up the inside of the rim. Sounds like the Company that makes Ride-On has eliminated all those issues and eliminated traditional balancing....

Thanks again for the info. I drop into the local bike dealer and grab some!

Rear Wheel Bearings

Hey Kurt,
Take a look at this rear bearing repair thread. Lots of pictures as well.

SO...IF you can find a USA provider for this special bearing, you'll make many XS11 owners very happy!!!

T.C.,
I just got off the phone with one of our bearing suppliers (open 24/7/365). They have a "FAG" 5904 In-Stock. HOWEVER, it may not be correct. According to the rep. it is 20mm I.D. x 37mm O.D. x 25mm W it's a needle/roller angular contact bearing. BUT, the overall width dimension is actually 23mm as there is a 2mm extension of the ID. The correct dimensions are apparently 20/37/23 according to the link.

I don't see an extended I.D. on the sample in the link. I didn't actually pull my bearing as I didn't have a replacement. I will get my parts guys all over this on Monday morning!

Sincerely,
Kurt

Hey Kurt,

I happen to have one of the ones that John England had gotten and provided to many of us "Yanks", and so I just finished taking some photos of it with the Caliper to demonstrate the dimensions along with the box for the brand/model # as well! They are not in perfect focus due to having to NOT use the flash!











So...Kurt, you can see from these that the actual WIDTH dimension IS 23mm, not 25mm?? The outer edge of the ID ring is 25mm!

SO....looks and sounds like you might have found one after all !?

Hey Kurt,

T.C.

TC,
What I BELIEVE the Rep was trying to describe to me verbally was that the WIDTH of the ID was <-Wider-> than the width of the OD (The ID extended 2mm beyond the width of the OD).

Your third photo placed seems to show the ID extending a bit? Maybe that's just the way you have the ID inserted into the race?

The rep was going to send me a .pdf drawing to my company e-mail. I don't have a VPN access on this computer so I can't go grab the drawing (until tomorrow a.m.).

Unlike McMaster or Bearings & Drives the company I called is not going to sell to the general public.

If the bearing looks like it's going to work, I'll buy a couple hundred of them on my corporate account and pass 'em out like candy at Halloween.

Now that you've posted some great photos, my parts guys will have an easier time finding these.

Kurt

Kurt, T.C.'s got you dialed in and the correct dimensions for the rear wheel bearing are 20x37x23mm.

The FAG number is in the 5904 family but Schaeffler doesn't have an image of the bearing I can look at, I can only find an ITN number. If it really is an angular contact bearing that's not the one you want, that's a combination needle and roller bearing:-

INA NKIA5904 Needle roller/angular contact ball bearings
single direction axial component, to DIN 5 429-2

Supplier has TEN(10) In-Stock on the Shelf NA5904 NTN-BR

XS Guys,
My parts guys found these in-stock at one of my suppliers locations. These are $27.08 per unit.

They have TEN ON THE SHELF TODAY! They can GET MORE!

Thoughts??????

I could easily buy all of these BUT they're a little bit too expensive to be giving them away like Halloween candy.

I need to speak with my wife to see if she is willing to ship them all over creation for you guys as I don't have the time to do that myself.

Please provide your thoughts!!!!

EDIT = NOTE: This is NOT the "FAG" bearing I found on the weekend. This is the actual NTN bearing shown in the photos above (posted by another person).

Hey Kurt,

That's great news!! I did a bunch of research the other day, but due to the site crash I wasn't able to post it last night.

There is a site called "Locate Ball Bearings", and they are selling a similar NA5904 bearing on both Ebay and Amazon, it's a SanYun (SYI) brand, but is the proper design with all needle bearings, hardened machines races and inner race in the correct dimensions, and surprisingly it's a bit cheaper ~$16.99 but then charges $9.95 S&H ! They are a bit heavy and will cost a few bucks or more both in postage and packaging/wrapping to mail regular US Post. I know it will fit into the SMALLEST Priority Mail Box which only costs ~5.00.

I don't know if the quality of the SYI brand differs or is much less than the NTN brand? Also don't know how much your SWMBO will be willing to deal with this process of taking/receiving payments...suggest Paypal vs. check/M.O.'s.

I'm tempted to write to the ebay store to let them know how to better describe their bearing so that XS11 members could more easily find it. They might also want to get in touch with Partsnmore.com to see if they might be willing to take a shipment and sell them on their site along with the other XS11 parts they provide?

Just as an aside for other members that are needing or wanting one of these bearings, that they need to be sure to search for NA5904, and not settle for NKIA/B5904's as they are like Scott/3Phase said...combo needle and roller bearings, and are not MACHINED and Hardened shells and races....and not up to the stress/rpm ratings of the NA5904.

SYI NA5904 specs: rpm=16,000 3050 kgf/dynamic load ; 4050 kgf/static load.

http://www.ebay.com/itm/NA5904-SYI-N...23#ht_60wt_916
$16.99 and 9.95

http://www.amazon.com/SYI-Syi-NA5904.../dp/B00DBOYVVQ $16.99 + S&H

Website LocateBallBearings.com that sells them in the above 2 sites.

I bought one of those SYI a while ago.

It measured correct.

I have it on the shelf for future reference, so I can't yet report about the fit.

Center Stand Modification (No left pipe)

XS Guys,
As the thread tells, my bike currently has no real exhaust only head pipes. I'm hoping to patch together something for the short-term and then properly fabricate a SS system in the next few months.

The OEM exhaust had a provision to stop the center stand and without the exhaust the center stand impacts the swing arm/shaft drive.

I added a small piece of solid round stock (1-3/4" +/-) to the stand to stop it's travel at an appropriate distance from the passenger foot peg and FAR from the swing arm. I tapped the piece for a 5mm screw and added a small piece of rubber. The piece impacts the frame cross member.

Even if I install a 4->->2 system, the modified center stand will stay this way to protect the exhaust.





Seemed like a good idea?

Kurt

[3Phase]

It's difficult to say, Kurt, what's it look like when the center stand is up and not deployed?

If it's not tucked up high enough you'll get some exciting sparky-lever action from the foot bar when you don't really want it in the middle of a left-hand turn.

Stand in up position......

It's difficult to say, Kurt, what's it look like when the center stand is up and not deployed?

3Phase,
After your post I took a look at it. It's probably a little low. The photo below is a little dark but the foot pad for the center stand is about 1" below the passenger peg. How far away should it be if in a stock-ish position?

I can very easily trim the added piece to get 'er up higher.. . . . .



Kurt

[3Phase]

That's some nice work!

It looks like the center stand is high enough and it's easy to adjust if it's not so I think you should go out and ride it just to be sure. It may take a lot of riding until you're sure you've got it right so be prepared!

.

[TopCatGr58]

Hey Kurt,

I think it does need to come up a bit higher. I'm posting a photo from our Brochures section, showing the left side of your bike/year/model, but the sidestand is down. But you can see the end of the centerstand that you put your foot on should be about level with the bolt that secures the rear footpeg. The curved portion of that part is to clear hitting the muffler, but just barely. If you are going to be getting sporty in your riding, then you'll want as much clearance on that side as possible.
