Remove stand & mounting plate from swingarm (or retrieve from corner of
garage so often referred to).  Curse designer who obviously never had to
ride through a rut with this huge appendage sticking out like a,  sticky out
thing.  Cut back the swing arm mount you've just removed the plate from so
it's out of the way a bit.

Weld to frame as in picture so the holes are just about horizontal & pretty
much in line with the footpeg mount bolt.  (Note my bike is a '91 but will
work with 95's etc if you play around a bit) You will need to tickle the
side a bit & just tack it in place.  The stand will now not extend past
centre properly so grind the stop point until it comes forward the same
amount it used to.  Then when folded up; grind the stop back quite a bit
until the stand foot rests right up by the side number plate (other
picture).  The toe of the foot will sink away level with the outside face of
number plate so that it can't catch you if you fall off the back, but still
not touch the tire.

It will probably require a little twist to get the position just right so it
misses the swingarm, (bounce on suspension to check).  Then you finish the
weld proper & hit it with some paint -job done.

At first I thought the bike leant over a bit too far & I was thinking of
screwing a bit of rubber to the foot but out on the trail this hasn't been
so.

Note the Just KDX design stand, now with the longer lever so that a 160
pound chap can lift it by hand rather than have to jump on it.

Also note the Trick wider 3 row pegs made by cutting another in half &
welding it on, cost $10.  Teeth sharpened with cut-off wheel.
