thats true... BUT, try as we might, we aren't writing canon here...

as good as the write ups are (or future ones may be) they are not always crystal clear. inevitably people have questions...

the way i look at it, if its THAT good, then no one is going to post a question anyway, so whats the point of locking it?

Re: Wheel Alignment: The String Thing

The factory marks are wrong on my new '07. FWIW they were correct on my '06 (Green - that was stolen)
Just did my first service. On chain adjust equaled up the rear marks with correct slack.
Tried the string check. They indicated out. ..Is this correct was my first thought.
I used the front of f/wheel for the front location, back thru the inside of center stands, and as far up rear as would alow without fouling on parts.
After many checks, then did a run out check on the rim at axle hight. Spot on.
The marks are just under half a division out.
Test run..speeds up to 75mph, no shake at any speed, even w/out hands.
-Alan '07 Silver.
Thanks FOG.

Re: Wheel Alignment: The String Thing

Hi guys. We use a tape measure and measure from the swingarm pivot bolt to the axle bolt when aligning the rear wheel. Much faster and dead on accurate. From that point we use the string method for lining up the front.

Re: Wheel Alignment: The String Thing

Please stop corrupting this method with complete inaccuracies. Your tape measure meathod is very bad Idea and will not cure anything as it does not addresses anything but the relationship of the two axles. any number of errors could be introduced into the actual alignment of the two wheels. You might as well measure from the seat cushion to the tail light.

You got a good Idea start a new thread.

I'm NOT corrupting anything! I'm in the pits all the time and see the techs aligning the rear wheel this way. Are you saying that all of these PROS are wrong?

Re: Wheel Alignment: The String Thing

I'm saying it an incomplete method. Your "Pros" already know where the front wheel is and they are only interested in getting the back wheel in line with a already known chassis. They spend $$$$ at GMD computrac too, or even own there own systems (GMD).
The string thing is a process that gets both wheels working, as best that can be even if the chassis may be bent. and is dooable by the average "JOE" it is well though out and tested.
You said "after you do the rear " then you do the string thing for the front. If the front is off , do you move the rear?.

If you want to offer another method, fine do it on you own not as a tag line to the String Thing.

Re: Wheel Alignment: The String Thing

I get what you're saying. But if the average "Joe" doesn't know that his front end is out of wack it may make things worse. Why put the rear out as well? The tape measure method does work for the rear.
It will also prove if the marks on the swing arm are out.
Sorry, I didn't mean to ruin your sticky... I thought the purpose of forums and threads were for learning and asking questions. Just because one person says it needs to be done a certain way, doesn't mean it's the only way or even the correct way.

Re: Wheel Alignment: The String Thing

That Video. is only Partially complete and good to only show the set up. The scale on the front tire is going to be a pain when you have to adjust the rear. I believe it missis the whole point of using this method to adjust the rear.

In any case this dosn't belong here I wrote the String thing as a set of instructions to help . not as a topic of discussion . Please move this "Comment" to a new thread.

Re: Wheel Alignment: The String Thing

I did this string thing when I put a new back tire on my (new to me) 96 500. I have the back wheel aligned to the front wheel, but the front wheel seems to be a little left.

Like this if it makes any sense
| <-Back wheel
| <-Front wheel

The bike is on a reconstructed title so maybe the frame is bent? I measure the "chrome" part of the forks and the left side is like a half inch shorter. Will doing the "rocking" fix this? Im a noob at this and still waiting for my dad to look at this, maybe Im just missing something.

Re: Wheel Alignment: The String Thing

You did it wrong. Your supposed to put the back wheel in the center of the front. What the hell did you align it with?

Re: Wheel Alignment: The String Thing

I ran the strings from the back wheel to the front wheel, then I straightened the handlebars to make the front wheel parallel. The strings are an inch from the front rim on the chain side, and half inch on the other side.

I understand I should tighten the tension adjustment on the brake side, but any more will cause the string to touch the center stand.

Re: Wheel Alignment: The String Thing

Check the vertical alignment of the front. And the center stand don't count. you ride on the wheels. Move it or relocate the strings.

Re: Wheel Alignment: The String Thing

I'm new to the forums, I have been researching many ways to get my wobble out? I'm not sure what to call it, when my chain was dragging loose, I took it into a dealer (usually they know, but now i know they can be impartial charged me $45 to almost break my chain, it was wayyy too tight, the chain was making screeching sounds at 65) anyway I got home safely and looked in my manual for a chain adjustment. So i get the gear to loosen my chain, 14mm for swingarm butts, 23mm for right side swingarm, and aadjustable open end. I noticed there was a cotterpin on the right side, so I removed it to adjust. Loosen the swingarm nuts and the buttplates, and used the stock marks to adjust the chain. When i tighten the stuff togehter its not fully 'tight' (as in i can turn the buttplate nuts and adjust the chain tension very easily.) I replaced the original cotter pin.

Any ideas why?

I don't want to really be all up and technical of this apparent string-thing that works, but before right when I bought the bike back in July 08, I could let off the throttle and it would 'ghost ride' striaght just fine. But now it wobbles a little bit. Is is possible the 'castle nut' is too loose and is 'wobbling' my rear wheel? Oh the bike is a 08 red Ninja 500R.

Re: Wheel Alignment: The String Thing

You must !!!!! tighten the Axel Nut to 80 Foot pound of torque or more. And since you posted it here in the string thing you must have read it. Why didn't you do it?

Re: Wheel Alignment: The String Thing

I can't wait to try this especially as i noticed that when i put the rear axle through and pulled it all together there isn't enough of the bolt showing through to locate the indicator bracket on the swingarm properly and it can move about 1mm either way on the end of the bolt

I centred the bracket on the bolt and then lined it up but i look forward to doing it this way and having some confidence its right.

If i have chance to have a go at the vertical alignment then i'll post some photos up. Probably won't be for a couple of weeks though. I need my dads garage which is only free on weekends. I'm n0t doing this on the pavement outside my house!

My bike rides straight and true with my hands off the bars but i think i got lucky and wouldn't recommend the way i did it to anyone!!

Re: Wheel Alignment: The String Thing

Have had new tryres fitted and just went through all the steps on this. The vertical alignement needed a little sorting which is strange as the bike has only had a very minor fall ( rubbing marks on fairing point and indicator but no cracks or other damage ).

Anyway if you haven't done all this do it. It's like riding a different bike when you get it right

ok so let me get this straight ?!? i take a string and run it down the left side of the bike
then take a second string and run it down the right side of the bike,
then move both stings together till they touch the edges of the front and rear tires,

now this is where i get lost!!!
1 where do i measure? front of bike, undercarriage, rear of bike
2 do both tires need to be completely removed from the rim's?
3 what do you do to prop the bike if you don't have a centerstand? i'm sure/positive the kickstand would create a lean...
4 what do i loosen or tighten? the axle bolt's


my left rear tire from a standing point behind the bike is cocked left...
the bike only wobbles when i take my hands off the grips soon as i put a finger on it, it straightens up...
i rode the bike a few day's ago and it didn't have this wobble at all
the only thing i did was put the front caliper and master cylinder back on

note to keep in mind, the bike HAS been wrecked previously into a house, speed unknown, and the only major damage was the upper fairing, fairing stay, and left can, gauges and everything still work but due to crash the mounts broke off so i haven't had it on the bike to give you an accurate speed... i will take a picture of the back wheen tomorrow and post it here if i can figure out how lol... and i'll take the front brake caliper off...

Re: Wheel Alignment: The String Thing

You don't read well, the strings are supposed to show you where the rear tire is pointing. they never will touch the front tire.

so what your saying is the string thing is BOGUS!!! I can look at my rear tire and tell you it's off center, you could be blind and see that!!!
perhaps if you were a lil clearer with your choice of words or maybe even made a video of how it's done on youtube people wouldn't ask you question's that you never answered!!! and your so called thread wouldn't be cluttered with question about the blank spots!!! i'm not saying you don't know what your talking about cause apparently it "worked for you" least you say so... i'm sure everyone here knows the rear tires is bigger then the front so your going to create a /\ line effect anyway... then you can look at it like this IT'S ONLY STRING what's to tell you have this STRING exactly straight with the frame or even the swingarm for that fact?

If you can't pass high school geometry, don't bother even thinking about it. Go get charged $40 for an alignment, or do some simple searching on these forums as the issue has been discussed at length. You're not some great Ninja crusader that's suddenly blowing a murder mystery wide open here, you're simply somebody that has completely misunderstood the concept of what is being taught and then based conclusions on top of flawed understanding. Dozens of people on here, probably even hundreds, have aligned their wheels using this method, and suddenly you're the the messiah that's going to prove everyone wrong.

Read this again:
Check to be sure the string is just touching the same part of the tire on all four points and not touching any other part of the motorcycle. Move the front stands so that the string just lightly touches the front edge of the rear tire and is not bent over it.

Now the strings show the path the rear tire is taking on its way to the point where the front tire was. I said that strange sentence to illustrate the point of what were doing here.

Now turn the handle bars to make the front tire parallel to the strings.

Now measure the space from the string to the front wheel rim on both sides. Both measurements should be the same w/in 1/16Ē

ok like this i()i with "i being the string, and () being the tire,
i()i
then what do i do loosen the rear axle and adjust till it's aligned with the front tire?

Re: Wheel Alignment: The String Thing

From the 1st post in this thread, as part of the directions that you can't seem to bring yourself to read and fully understand:

Quote:
Now measure the space from the string to the front wheel rim on both sides. Both measurements should be the same w/in 1/16Ē

If they are youíre done.

If they are not: adjust the rear wheel chain adjusters to correct the error.

Re- set the strings and measure again. Repeat till OK.
