LT250 Front Camber Mod
« on: October 01, 2012, 09:52:31 am »
I think most everyone knows this modification, but if not, here it is.

All LT250's were originally built with positive camber. Positive camber is when the top of the tire is tilted outward.
When turning, this allows the tire to roll over on the side wall making the handling less than desirable.

Here's the fix:
 1) Remove the lower ball joint from the lower a-arm.
 2) Grind the 2 "flats" on the lower arm that locate the ball joint FLUSH.
 3) Find or fab some washers/spacers approximately .200" that have the same ID as the ball joint OD.
 4) Slide the washer over the ball joint and reinstall. (Note: use an adjustable wrench to hold the ball joint from turning)
 5) Re-set your toe-in alignment.
      Note: do not go over a .200" spacer/washer as the ball joint bolt will not have enough thread "bite" into the ball joint.

Here's a small photo showing the finished setup (note: I machined down a blue hex nut instead of using washers)

Wasn't this the flamed wonder bike that was for sale?

This mod goes for the 500 too.
Ain't ever seen it......but I have heard it.

Key word "was".
Keeping it for my 2-stroke fix until the hybrid is done.

Yes, 500's can do the same camber mod.



Same mod as the 250.  Grind down the ball joint lock tabs, find some washers that are .200" and install them.  Once complete, reset your toe and your good to go.

For the record If you get longer bolts you can go more than. .2"
I Think I went .375 to get the wheel to be @ 2 deg negative. I used some Cromolly tubing I cut on the lathe.

I doubt it I did it on mine before I went to Burgard arms That was probably7+ years ago. All my stuff is  Yfz 450 based now and has been for a few years. I think I gave all my oem a-arms away. If I still have a set I can mock it upagain but don't hold you breath.

 I don't know why I never thought of that, that is a great idea and I think I have the right size tubing. Just need to find the longer bolt.
I'll post pics when I get it done.

This camber mod, combined with the bump steer mod (flip flopping tie rod spindle brackets) is one of the best and low buck improvements you can make on a 250. Glad I did it!

You mean that the tie rod bracket would be pointing out toward the wheel?

I have a beauty thread pitch checker with the metric hole sizes aswell. Does the trick. Metric thread pitch can almost allways be described as being course or fine thread thou. the hole size most important.

Armadillo or similiar has ball joints that fit our bikes and they are adjustable width and look a little better than stock in my opinion. Im not positive that the design is as stong as stock ball joints as they have alot of metal between the joint and the mount compared to the skinny looky armadillo's. I am thinking that only 2 are needed and should perhaps be mounted on the upper aarm not the lower, if the strength is notr there.... Rockymntatv sells them for around 25 apiece :)

Could be there so you can safety wire them so they don't loosen up and come out.
