F6B To The Dark Side

[bob109]

, okay Bob, I am listening. Please keep me informed, either through the forum or a PM, to let me know anything and everything you can about your experiences with this tire on this F6B. I am more than willing to...learn.

As for TexasTC's idea of powder-coating the wheel, I have had that done on all 3 of my GL1800 Wings, and my local powder-coating company charges me 100 bucks per wheel. I am happy with that. With the powder-coating, you know it is a good hasrd surface, and the wheel cleans up easily.

Doc:

Thanks for the advice on the powder-coating. I have a local company, Sterling Products, who does powder-c and may go that route in the future.

I promise that I'll keep some very detailed records of my experience with the G-MAC CT. I have a Laser Thermometer that will be used for capturing tire temp after low/high speed riding. I'll perform that procedure on the current Bridgestone and have that info for future comparison. Along with the install mileage/date, the capturing of tread depth will be recorded every 1K miles. I initially plan on taking the bike to the nearest large parking lot for some repeated slow turn maneuvers. I like to get a feel for the tire before blazing out on the highways. Like a MT, assuring the "mold release agents" are scrubbed off will be another first on the list. Usually while the tire is in the static balancer I'll rotate the tire and hit it with some course emery cloth by hand.

Additional photos will be added to this post as time/things progress.

P.S. If and when you publish that book put me first on your list for a "Autographed Copy"

Put me on second

Btw for some more interesting reading, Neil Peart the drummer for "Rush" also has a series of interesting books about his motorcycle adventures. He rides his BMW in between shows as he travels around the world.

Any connection to your screen name?

I'm a huge Peart/Rush fan. Have seen their shows several times -always great!

Bob, and there in lies the problem. You read what you wanted to read and NOT what I posted. The weight or additional weight in and of itself is NOT a huge issue. What you didn't get was lateral force applied to the FD's bearings. So maybe before revisiting you should look into it some more.
As I stated I have no interest in fighting over this with you. I am pretty sure some fella's with a whole lot more engineering experience than I have a better knowledge of what should not be done with the parts they designed. I'll leave it there.
May your journeys all be safe......

Gumby, why would I not open this thread? I find it of some interest to see what folks are doing with their bikes. Why so defensive over opposing views?
Obviously I am not going to change Bob's mind, nor was that my intention, but I did point out a few flaws in the DS argument. Won't make any difference to those who want to run DS, might for someone on the fence.

As for the "can't find any" DS failures? Didn't look too hard because there is one posted to youtube, and it was a wing.

Ride safe fella's.

Once again "Thanks" for sharing that with me

As (your quote) "I didn't get what was"lateral force applied to the FD bearings", I'm giving you the podium so you can share your knowledge on this subject. Please explain it in layman terms so "I get it" along with all the other folks who are following this thread. I know you will clearly articulate the difference between the MT/CT lateral forces so there's no mistake on anyones part on this subject, which you raised as a issue. Thanking you, "Teach", from all of your inquisitive students. Were listening!

You Ride Safe Also

I couldn't find it on YouTube can u post a link ?
I still putting it on my bike ! Just would like to see the video.
I Have been riding the same roads Keeping track of my speeds
So I can do a fair comparison When I change the tire.

Found this intense article on the web about CT vs MT.

Yes, as a matter of fact it is. I'm a big fan too, really enjoyed reading his books and seeing RUSH in concert. I originally saw them at the swing auditorium in San Bernadino when they played backup to another band during their 2112 album concert. Just blew away the audience.

Bob, sure I can, but it would be much better if I just quote a fella I know who knows more about DS conversions than anyone else.

"If the centerline of the wheel stays in the same place, then static loading on the final drive bearings remains the same, regardless of how you get there.
All that the bearings 'see' is how far away from me is the load applied (centerline) and how much (total mass being supported at that wheel).

If you offset the wheel farther away from the final drive, then the output shaft will see a larger moment load which will result in addition loading on the bearings.

Imagine a bar held horizontally in your hand, as a weight gets moved farther out away from your hand it has a greater torque load that your hand/wrist much resist in order to keep the bar from sagging.

-----

Now, imagine adding extra weight at the same spot on the bar you are holding, and you will agree that it also takes more work to hold the bar level, right?
That is analogous to what would happen if you go with a heavier wheel/tire.
OR..... if you add extra mass.

Except, our wheel assembly is not hanging out in space, it is resting on the ground and holding up the final drive (and rest of the bike/rig).
So when stopped the extra weight of the heavier wheel has no effect on the load seen by the final drive bearings.

BUT....
You didn't buy the bike/rig just to have it parked and looking pretty, so you drive down the road. And while driving down the road you will hit bumps, causing the suspension to move.
NOW that added wheel/tire mass does have some effect. The wheel/tire/final drive/swingarm is all mounted "below" the spring/shock unit and is refered to as the 'Unsprung Mass'.
Greater unsprung mass affects how quickly/well the suspension can react to being bumped. Basically, it takes more energy to both get it moving, and stop that movement when you have more mass.
Which means that with a heavier wheel/tire your suspension is going to feel harsher, and in some cases may not stay in contact with the road/trail as well.

And, there is then an inertial force that is transmitted to the bearings of the final drive as the wheel bounces around on the end of the output shaft. The larger the mass that the final drive bearings are trying to control, the more load the bearings see.
The heavier the wheel/adapter, the more force transmitted. And, the rougher the road/trail, the more inertial force transmitted through the output bearings due to larger/faster/more frequent movements of the unsprung mass.

Yes, inertial loading is probably a smaller component to the final drive bearing loads than static loading, but NOT insignificant."

Hope this helps.......
