Title: Mean Streak Rear wheel
Post by: TinSoldier on June 03, 2015, 01:46:40 pm
Well, the time has come.  I just ordered a set of Avons for my stock wheels.  I have been reading about the dwindling choices for rears and now I have to deal with it first hand.  In reading about the conversion, it seams that finding a machinist to do the work is going to be difficult.  I started to wonder if anyone has tried modifying or replacing the caliper mount instead.  I think there is plenty of room to "move things around" to fit.  Anyone looked into this option yet?

I dont have the background on the other option, but I did not find it that hard to find a machinist to do the work.  the difficulty might be in the "how much" category.

If you have the OEM bags, I highly recommend that you machine the wheel to move the rotor and caliper inboard, otherwise the caliper will be very close or even in contact with the bag.  Since the bags tend to move around in motion, so this could lead to the brake dragging and/ or the bag wearing through.  Machining the wheel not only allows the use of the OEM caliper mount but insures there is adequate clearance between the caliper and bag.  I used the Mean Streak rotor without machining the wheel and made my own caliper mount, but I have aftermarket luggage that leaves plenty of clearance.

As for finding some to do the work, the machining can be done on any mill or lathe with enough capacity.  Google "wheel machining services" to see if you can find someone in your area.

I think Jan Trento used a Meanstreak rear caliper and modified the caliper mount but those posts would have been lost with the meltdown.  IIRC you had to remove 1/4" from the mount to get it to fit and then work out a caliper bracket stay (he modified the swingarm and bolted it the same as a Meanstreak, I think) but I couldn't say for sure that there was no wheel machining.  I bought a wheel and caliper from him a LONG time ago but ended up having the wheel machined and used a Nomad rotor after a friend volunteered to do the machining for free.

I will be doing the front 17" swap in a couple of weeks when I need new tires and THEN I can try out the new PR4 GT's I bought over the winter.

Thanks for the input.  I know about the proceedure that's been posted here.  I was just looking for an alternative solution.  I thought i read a post somewhere that it could be done without modifying the wheel.  I just cant find it again.  In looking at the stock setup, I can see enough room for the caliper to be repositioned  to line up.  Just curious about any prior attempts to make it happen.  I plan to get the MS wheel and Vulcan rotor anyway and I may do the engineering just for fun.  With the new tire in the mail, I have time to play with it.

GF-in-CA Thanks for the heads up on the bags.  Perhaps spacing the antlers would give back the clearance.  I know I should be able to find a shop here in Richmond when I start looking.  Sometimes my mind needs to get back figuring stuff out to stay active.

Sport Rider,  Thanks for the invite.  I will let my friends know and we may make it there.

RodWpg,  I think you found exactly what I was looking for.  It is food for thought when I get the wheel.  Actually, it might be two wheels since my brother has my '88  and needs the same mod.

Thanks again to all.

The non machined Mean Streak wheel swap was me. I have been riding for a while now with no issues. As far as any interference with the MS caliper and Connie saddle bag..... there is none. The way the right side bag is shaped, there is a cut-out that the MS caliper lines up with (see pictures). I have had ZERO contact with the caliper and saddle bag. As I have said before, I don't claim this is a better way to mount a MS rear wheel, just a different way.  ;)

Definately thanks to you TxFatboy for your work to make a "what if" a reality.  Your method may not be any different in costs but it may save time by not having to locate a machine shop. A good welder should be able to handle it.

Woody can correct me if I'm wrong, but I believe his solution still requires some machining of the Mean Streak caliper bracket to narrow it down.  Still easier than machining the wheel though.

Gary, the Concours and MS rear calipers are about the same width... just under 4.5 inches. And yes, the MS caliper bracket had to be machined to the same thickness as the Concours caliper bracket.  I think the total was 0.180 inches (0.09) from each side.

Here are a few pictures of the process and finished (gray caliper bracket).
I like the way you used the Mean Streak wheel, but was wondering if it would be possible to fab a brake caliper stay, instead of the tube welded to the swing arm? I am a welder, and I was thinking of making a Connie brake stay modified to fit the Mean Streak caliper bracket, bolted to the same spot as the Connie brake stay. Do you think this would work? Also, when I install the wheel and caliper bracket, why would you take .09" off of both sides of the caliper bracket for a total of .18", instead of taking .18" off the outside face of the  mean Streak caliper bracket? It seems to me that the distance for the caliper to fit the rotor should not change when transferring over the whole Mean Streak wheel and brake assembly, and by taking .09" off the inside face, it would make the caliper offset in by that much on the rotor… am I thinking correctly? If so, the machining would be a simple cut of .18" off the outer face of the bracket, giving the same overall width as the connie wheel and brake caliper bracket. Let me know what you think!

The bracket is made from 5/8" aluminum plate and was machined with a .300" "notch" to mount the caliper so it lines up with the rotor.  1/4" aluminum spacers on either side of the bracket center it relative to the stay arm, as shown in the second picture.  I used the OEM bracket as a pattern and offset the mounting holes and stay bolt hole the required amount to work on the 300 mm rotor.  No problems to date   :motonoises:

 When converting to the 15" Eliminator wheel on my C10 I came to an early decision to place the caliper outboard 1/4" due to contact of the black caliper frame with the rotor.
 So $25 machining charge on the outboard face of the bracket hole common to the axle and two 1/8" washers inboard to maintain the width.
  One with a good eye could cut/file saving machining cost.
 Just saying that KISS works sometimes. Have no idea if this is applicable to this threads wheel conversion.

Gary, I like this idea, but I was thinking of using the Mean Streak caliper bracket, and making a .18" cut where the axle and swing arm are for the proper width, and then fabbing a brake stay down to just above the swing arm for the Mean Streak caliper and bracket. do you think this is a good option? I am trying to use what I have, and the less complicated the better. If the tube welded on the swing arm works, then a brake stay from the stock location to just above the swing arm should work also. What do you think?

JDM, the rotor is from a 1999-2004 Vulcan Nomad, Kawasaki P/N 41080-1447-CM, or EBC P/N MD4150.  You can also turn down the rotor, the C10 rotor is 280 mm dia and the Mean Streak rotor is 300 mm dia.

I think I understand what you are trying to do, and it should work.  If you can visualize a line between the axle centerline and the hole on the bracket that attaches to the stay, I would try to make the angle between that line and the stay as close to 90 degrees as possible.  If you use the existing hole on the Mean Streak bracket, this would mean rotating the caliper around to the back of the rotor.  I know of another owner who used the Mean Streak bracket and chopped off the stay arm on the bracket and drilled another hole closer to the caliper, then attached the OEM stay to that.  It worked well.  Hope that makes sense.
Title: Re: Mean Streak Rear wheel
Post by: Yamahawk on June 27, 2015, 03:38:52 pm
Yes,
     It does make sense, as you wouldn't want the bracket to move around, hence the 90 degree between the stay and the bracket. I am thinking, that it shouldn't move much though, even if it isn't 90 deg. as the axle and bracket hole would have a fixed point, and then the stay would also…. I will think on that. Moving the caliper around to the back side of the rotor would actually help clearance with the bag too, as it would lower the caliper in relation to it…. i think lol.
Title: Re: Mean Streak Rear wheel
Post by: Bob_C_CT on June 27, 2015, 06:26:40 pm
I cut down the meanstreak rear rotor. Was going to do it on a lathe but it is an interrupted cut when you get to the holes. A friend wired it on an EDM machine for me instead. If you use a lathe take light cuts when you start getting into the holes. If your Meanstreak rim doesn't come with a rotor (mine did) a Nomad is much easier.

The 90 degree number is to minimize the force in the stay, and since the OEM parts are at that angle, it will keep the force right around what Kawasaki designed.  You're right that as long as the bracket/ stay/ swingarm form a triangle, there won't be any movement.  Moving it 10 degrees one way or the other won't make much difference in the force, but getting them to where they are close to parallel will increase the forces significantly.  All in all, you're better off trying to keep the angle close to 90 degrees.

I got the MeanStreak rear installed, ended up milling off at least a 1/4" around the axle hole on the caliper bracket. I clocked the caliper back at 9 o'clock, and used the brake stay from the Concours, just cut off the inside ear of it, and drilled a larger hole for the M12 bolt that threads through the caliper bracket. This ended up around 87-90 degrees in relation to the bracket and stay. I have to say that it was pretty easy to do, only took a couple hours to get everything done. I had a friend make me up a 22 1/2’’ brake line (stainless) and it clears everything well. It is on, now to go for a ride!! :D
Title: Re: Mean Streak Rear wheel
Post by: Yamahawk on July 21, 2015, 09:25:32 pm
My cell phone bit the dust, so no pics yet… but, after the test ride, I found the stock length of the Connie brake stay was too short for clearance on the right bag, the caliper was hitting it on bumps. So, I cut a piece of stainless 1/2" pipe and made it 2 1/2" longer, and clocked the caliper around to about 8 o'clock. Now, all is well. It handles pretty good! I have to work on tire pressure etc, but I like it.

This is why you machine the wheel. Another advantage is being able to put the stock wheel back on in case the meanie gets damaged. Glad it worked out for you.

Post by: Yamahawk on July 22, 2015, 10:11:32 am
Yeah, I can still replace the Concours rear wheel, I purchased another brake stay and modified it and kept the stock one. The parts are all from the Mean Streak that I installed except for the modified replacement Brake stay. It works out really well, If I ever have to re-install the original stuff, all I have to do is bolt them on, re-bleed the original caliper and line, and its all good to go. I cut the ends off the other 06 Concours brake stay, and welded them to a 1/2" stainless pipe (I'm a retired pipe welder  :great: ) and made a custom length stay, that clocked the caliper around the back side of the rotor, giving plenty of clearance for the right saddlebag, and kept the right angle orientation for the caliper bracket and the brake stay.

I agree. It made the bike more manageable and handles better too. The height is about 1" less or at least it feels that way, and it gives a better slant to the bike also. I put 22 miles on it last night with the wife on, 40psi in the rear shock, and #3  damping setting, was nice and stable.

I hope not. That would mess up the bikes ride geometry. When I did my mean streak upgrade the bikes height stayed exactly the same from stock to mean streak rim.
It was designed to do so. You dont want to raise or lower the rear or the front specially by an inch. That is a lot.
Title: Re: Mean Streak Rear wheel
Post by: Yamahawk on July 23, 2015, 12:10:55 am
Mike,
  It just feels that way. The 170/60-17 is actually only a 1/4" lower really, but the 120/70-17 is almost 3/4" shorter than the 120/80-18 that I replaced it with. I can tell the front is lower, as I look a little more over the top of my Rifle windscreen. I have to experiment with tire pressure, and it seems that it likes more than 40psi in the front and rear. I get a little wagging with the lower pressure. I has 45 psi in both, and it rode really well. I will try in between, 42-43 psi and see how it does. It definitely does corner better, not as well as my race bike, but better than the stock geometry tires.

I am running 42psi front and rear. Sweet spot for the Dunlop Roadsmart 2. I used the 160/70. It is not for the inseam challenged for sure. Feels significantly taller than stock.

Pbfoot,
you and I are running the same f/r setup.  my rear tire is set at 42psi but I have had good luck running the front at 39psi.  someone before me (GF-in-CA?) did some calcs and the 160/70 wasn't a lot different in height from the stock 150/80.  it did slow the tach a little.  I haven't noticed it being hard to get on or hard to plant both feet at an intersection.  and the RSIIs definitely grip way better in the dry and wet than the OEMs did.  but that's understandable.

Not a big difference but the first time I sat on it I could tell the difference. I have been running this since October, about 4000 miles. Very confidence inspiring. Front suspension is done, I think I will try a heavier weight oil in the rear shock.

I changed the air pressure to  little over 42psi front and rear, and it is very stable. I had the occasion to take it up to over 100mph on the entrance ramp to the e-way this morning, and it was extremely stable, and felt very planted, even on deceleration. So, I think that is where I will keep it. The rear shock had about 29psi, and 2nd damping setting. This is a little light for two up, went for ice cream tonight with the wife, and will try about 38 psi loaded and with the 3rd damping setting for travel. It might need even a little more rear air pressure but, hey thats all good.  :beer chug:

Here are some pics of my rear conversion, using all MeanStreak parts, and a modified Concours brake stay. I had to cut one ear off the rear of the brake stay, and used 1/2" stainless steel pipe for the stay, 2 1/2" longer than the stock solid rod used by Kawasaki. This clocked the caliper down about 8:30 or so, clearing the right bag well. It has Great Brakes in the rear now, much better than the stock one.
