Rotor turning/resurfacing in Colorado?

[rgoot01]

Exactly. It's cool that there are other riders/individuals who genuinely have a concern for another persons well being, especially when not knowing the other person. I can assure all here that If I honestly didn't feel that it was safe in any way, I would not even think of attempting to do it. I am not one to do something if I feel it may not be safe. Hell I used to tear down haul trucks in the quarry I used to work for, and I can tell you this, you don't bull**** with safety when 100 tons of truck is raised above you. Look I'm not trying to get in pissing match.

That's it

You hit the nail on the head. We have enough buddies who go out way too soon. All of us here would rather not see ANY punch their ticket early and try to dissuade iffy actions. There "were" a lot of people who thought they could get away with something and didn't. With all that said we still respect each other's rights to do as they please. Just don't expect us to be happy with tossing flowers. There's few enough of us as it is. I think you understand.

Rotor resurfacing

After reading all your comments about this topic, doing some research and asking lots of questions, I believe this insight from one person that does the work. The rotors can't be "turned" as we understand it. He resurfaces them. If the rotors don't have a lip at the edge, it means they are not worn down, as the pads would create the lip when wearing down the face. In any case, he would not do the work if he had to take too much off. Mine was just badly scuffed and looked rusty. As I don't have the tools or knowledge, I sent the rear one to be resurfaced and drilled. This is how it came out.

It looks nice, any idea what what process or machinery he use to do it? Any idea what the new thickness is? Too bad it wont look the same after 5000 miles. :P

[rgoot01]

Now thats a nice rotor! Thats what I would like. I just want it cleaned up and drilled. The rotors I have are good to go, just want them drilled and cleaned up like that. Think I will drill them and then just clean up rust with coarse scotchbrite. I like bikerphils rotors with the 3/8 holes rather than 1/4. I was thinking of doing the same pattern,but doubling up on it. Are there any limits to number and size of holes I drill. Also anyone got other pics or variations of patterns.

What does something like that cost to have done.

[XS1100 Newbie]

I would agree with him that it is not worn if there is no ridge. If it is warped, that is a different story. Usually a warp you can feel is over .006. He is probably using a flywheel grinder to surface them. I had thought about asking the machine shop i use if they would do it.

this mean with no front brake it will take you 70% longer/further to stop then a bike with both brakes

That doesn't compute. Kinetic energy increase/decrease nonlinearly... Meaning, doubling speed increases far more than double the kinetic energy. Likewise, say for instance with a good set of front and rear brakes stopping at 100%, you have a stopping distance of 100 feet at whatever speed. Reducing your brake stopping power by 70% isn't going to simply add 70% distance to stopping distance.

So, in actually calculating it, a bike traveling 60 mph with 100% braking front and back brakes has a stopping distance of roughly 140' under perfect circumstances with a friction coefficient of .86. At a 30% braking rate, the same bike in the same perfect circumstances is going to need 465' to stop. More than triple the distance! Most bikes are going to stop on the 35 yard line.. your bike won't stop inside the stadium.

The rear brake only works fine. Rather than be negative why don't you look at it this way, I obviously have a greater confidence in my abilities than you have in yourself.

I don't care if you're the best rider in the world with there being none equal to your level of confidence. Rear brake ONLY isn't fine and doesn't stop well no matter WHO you are. Having confidence in a rear brake only setup.... I think Ivan pretty much nailed it. You may have yourself fooled, but you're not gonna fool me.

Not trying to crack on you or spread bad juju or anything, just stating the facts. What you do with those facts is up to you.

Good luck.

Pretty harsh replies for someone not looking to get in a pissing match.

FWIW I am sure my skills are vastly superior to anything you might assume or posess.

[daveyg]

Well I can piss past the 50 yard line! JK My choice is to not use a rear brake only system. Sure that under most circumstances I never use the front, but there have been instances where I have needed to and have been damn glad it was there and worked properly. Take it or leave it is up to you.

[crazy steve]

Before you go with a rear-only brake setup, it might be good to see if it's legal to do so. You see lots of 'show queens' running without legally required street equipment, but that doesn't mean these are daily riders.

As to the advisability of running no front brake, I'm sure you'll change your mind the first time somebody pulls out right in front of you and that rear tire locks up....

... assuming that you survive.

Quite frankly, I could care less if you have no regard for your personal safety and won't shed any tears for you. 'If yer gonna be dumb, ya gotta be tough'. But it does irritate me that I'll get painted with that 'dumb biker' brush that will come out after.

Where is that popcorn eating smiley, I really need it right about now.

BTW - sorry my last post was not mathematically correct, I'll take notes and try to do better next time.

For rgoot01,

From Sport Rider: (this was using a modern Bandit 600S and professional rider, you distances will be longer)

Our braking distance from 60-0 mph using only the front brake was 151 feet.

And rear brake only:

Braking distance from 60 mph using only the rear brake was a long 289 feet.

Both brakes:

For our final test, we modulated both the front and rear brakes simultaneously. Not surprisingly, we brought the motorcycle to a stop in the shortest distance of the three tests: 146 feet. Both brakes together undoubtedly provides the best braking performance.

My 1999 Toyota Camry stopping distance @ 60 mph: http://www.edmunds.com/used/1999/toy...549/specs.html

Braking Distance (60-0 mph): 133 ft.

So, when you end up following me and I have to slam on the brakes for that stupid kid in front of me you will become a Camry/rgoot01/Yamaha sandwich. Please pin your insurance info to your ass so I can get my repairs done in a timely manner...thank you.

[Ivan]

I had another thought...

I doubt the XS11 even retains 30% of total breaking power with the rear only. Everytime I hit the rear hard without using the front to help settle the suspension, it hops like a jackrabbit on crack. So that 30% just got divided into another 1/2 at most.

[hightec_redneck]

hey rgoot01, sorry my note got you into such a nasty discussion. I did not go into the details as to how I did it and how I checked it out when I was done, because I did not know if you were interested. And from some of the responces you recieved I am glad I did not. It is a shame that some people have nothing better to do than pour out their negitive opinions, instead of a simple replay to be careful not to get the rotor out of specification as it will cause the brakes to not work properly. Anyway, if you need any help just send me a private message and I will explain anything I can.
