YES MY BROTHER WANTS TO TRY PILLION ON SHORT RIDES DONT KNOW WHY THAT SEAT DONT LOOK CUMPHY BUT WHAT THE HELL MY FIRST TIME WITH PILLION ON BOARD SO WHAT ADJUSTMENTS CAN BE MADE AND HOW AND WHERE CHEERS ANY HELP WILL BE APRIECIATED 88 3EN1

First off, you need to fix you caps lock key it must be broken dude!
On the top of you shock is a stepped cam, turn it clockwise to increase preload the other way to decrease.
If you don't have the c spanner you can use two screwdrivers one on each side

as above ... but with out the screw drivers

Put some more air in the tyres - a copule of psi in the front and about 4 in the rear.

Take it steady, don't try an be a racer because the bike will feel very different with a pillion ... remember brake early and don't slam them on, be progressive.

will be doing the things you suggested next time done a dry run with no changes to tyre presure or adustments to the shock only went 4m circut on damp roads with this set up the back end was vvtwitchy i didnt feel safe at all i was glad to get back to my bro's upright he on the other hand said when we goin out again
