I know this post is a couple of weeks old...but here's my setup:

If its bendy go with 1 or 2 degrees Caster, 2 degrees negative camber and 4 to 8 mm toe-OUT

If its more straight go with 3 to 5 degrees caster, 1 degree negative camber and 4 to 8 mm toe-IN

good luck!

Just cut it off and put some forks on it, then you won't have to worry about toe in and out.

Nice trike advice Smile

As JRE suggested, add a bit of toe out for general riding.
Not for speedway though, it will increase your 'toe-out on turns' which will slow you down when on opposite lock and make catching a loop out a little harder.

6 deg castor should be enough, but try more if your steering is still light.

How are you measuring the 6 degrees castor?

Surprised ..I see that the riding setups in Oz are WAY different then the way we setup here in Holland.

6 deg camber/caster? ..If i would run that, then the first tabletop i hit would be the end for the front hubs i think.
1 or 2 deg is enough... in Holland that is..Wink You can also set it up by pressing down on the front suspension. When you reach the maximum travel you get on the track you ride,then the wheels should be straight up(0 deg).

About the toe-in/out, When we ride sand tracks we go toe-in and when we ride hard surface, we go for toe-out.

I run the Houser Slicasts on my TRX450R. It has the quick adjust pins on the ends with the degrees on them for the caster adjustment.
Like on a motocycle,the more backwards leaning the hub is(on a bike the forks)...the more straightforward stability you have. More straight up wil make you turn better but you get less straight line stability.
On the bendy tracks(which are usually hard surface),we go for 1 or 2 deg caster. on the sand tracks we run 5 or 6 deg caster because the tracks have deep lines to follow and you want to stay in that line.

How do you like the Houser Slicast Arms, been thinking of changing the TRX ones.

I remeasured the toe in and now the front end has settled in it had 5 mm toe in, adjusted it to 4mm toe out and will give it a squirt on Monday.

It doesnt get used for speedway Bullet, only trail riding and am measuring the angles with a degree thingy that my mate uses on his sprintcar, its got a straight edge and a degree thing that floats in fluid, I check the caster on the ball joint threads and camber on the rim edge

Ok sounds like you are measuring the angles well.
I just asked because graduations or indicators on aftermarket arms don't account for the frame angle that they are essentially bolted to.
If when you ride the bike is sits nose high or low, that will change your castor before the indicator on the arm knows about it.
Even going from 18 inch rear tyres to 20's, would knock maybe a degree off your castor.
If your castor goes negative under brakes, the front end gets that 'fold underneath you' type feel about it.
The only real disadvantage of too much castor is heavy steering.
With your measurements, if you feel the steering is generally too heavy, i'd knock the castor back to 3 degrees first (leaving 2 - 4mm toe-out).
But remember to check your toe-in again after making camber and castor adjustments.
On some types of adjusters (probably most types) your toe-in will change.

The 5mm toe-in you measured will be the twitchy, fast steering response you were trying to cure.
They start to get pretty sketchy with more than 5mm toe in.

Your new 4mm toe-out will feel a lot flatter and smoother to turn, and you might want even want to run a bit less that that after you've tried it.
The only quads i run more than 4mm toe out are 4x4's, where the front wheels tend to pull forward under load.
For general riding, MX etc, I never run any toe-in on the DS, it's always somewhere between Zero and toeing-out.
But when it comes to the last 2 or 3 degrees of whatever angle, there is no real right or wrong and rider preference, type of quad, and type of riding account for bigger differences.

Some good advice from others too, sounds like your all over it now Smile

Think that Bullits post just explains it all!. especially on the Oz riding styles.
Dude really sounds like he knows what he is doing Cool

..The Houser work really well for me, they have been on the quad for 4 years now and they have been beaten down for that whole time. (The guy i bought it from was a europeaan championship factory supported rider)

even now they are still in very good cond. Im rebuilding the quad and replacing all bearings,but it wasnt absolutely necessary.
The quick caster/camber adjust works really wel to.

good luck with the setup m8..and ride it like you stole it! Laughing
