Help--I need to set Quadracer toe-in

[ccdhowell]

Today I installed a set of +2 a-arms from Fullflight Racing on my '90 QR. A pretty straight-forward job, but now for the toe-in. The camber is way off with the new a-arms, I guess I should start by setting the camber, anyone know a better way than just eye-balling it? As far as toe-in goes, I have the shop manual, but it calls for a special tool that would be kinda hard to duplicate. I know you can just use a tape measure, but have never done it and don't know the tricks.

Tell me the tricks ya'll know and what to look for when it's right.

Thanks,
Chris

The way we did it at the ATV dealer was we hung 2 triangles (They were about the size of the tire) and measure from bottom bar to bottom bar. I'm sure you could use anything as long as you can get a flush measurement, dont want it thrown off by human error.

I am not a guru at pro level quad suspension.
But I assume that the wheels are way cambered in at the top.
You want to get you camber and caster set before you do the toe in.
The camber is the outward/inward tilt of the tire top to bottom.
The caster is the amount the spindle is pitched forward or rearward.The caster adjustments will affect the ease of turning the quad.It also wil affect bumpsteer to a degree.
But start by setting your caster even.The arms will be adjustable with spacers or bolts at the pivot bolt area.Since you want to trail ride,harescramble it,you will want even settings becuase you will be turning all different ways.If you were just turning left all the time,you would want to pitch the right front a-arms more foward then the left a arms to help the quad turn left better.
The camber you want to adjust ,with your riding wieght on the quad.
You want the tires to make a 90 degree contact to the ground with your weight.In other words you want the center tread making complete contact while sitting on the quad.You will probably have to get a friend to adjust while you sit on it.
Then unload the suspension,to see were the camber is,via mid air during a jump.
A simple level taped to the front hub may help making adjustments.
The toe should also be set with your wieght on the quad as well,and should be with 1/16th to 1/8 of an inch of each tire.A tape measure will help set the toe in.
There is no concrete set-up. All you can do is start with a base line and play around to get different feeling from the quad.It is all in riding style and rider feel.

Hey thanks guys, I'm out to the garage right now to tackle the camber and toe-in. I'll let ya'll know how it works out.

Alright, I got it. Took me 6 hours...with no beer...caster at +7 degrees, camber at -3.5 degrees and toe-in is about 3/16 inches in. That should be good, I'm gonna ride it and see. Dang this was hard though, trikes are allot easier in this respect, and several others. Chris

I have always been under the impression quads are supposed to have a slight toe out.

[ccdhowell]

Everything I read warned against a toe-out condition, said it was dangerous. Over at QuadracerHQ Forums the concensus is to adjust toe-in about 1/4 inch difference front to back measured side-to-side from center of tire to center of tire. I guess every quad is different, IDK about anything else, this is my first quad.

do youself a favor and give it like 1 -1 1/2 of camber.


most guys use a square ......just hold the square on the floor and to the tire and measure the gap

[ccdhowell]

I did use a square, but I bought me an angle finder so I could read the degrees. The -3.5 degrees I have and what you said most guys do are quite close. I didn't measure the gap but at the end of my square it was maybe 1 to 1 1/2 inches off the floor. Angle finder will come in handy and was only $6 at Harbour Frieght.
