depending on your weight first you need to set race sag on the rear shock which should be around 100-110mm. compression and rebound adjustments are a matter of personal preference,and what kind of track you ride.if you are alot more than 190lbs you would need to have your forks and shock resprung and revalved.
Most stock motocross bikes with just supermoto wheel and brakes can get the suspension working OK - but not great.
To start I always take a motocross bike and go full stiff. Turn the clickers all the way in and go out two clicks. The rebound you might want to play with two to 5 clicks out.
As for sag - start with 100mm. Leave the fork in the stock position in the triple clamps - do not push them up in the clamps. If the bike works good - run it. If you get some front wheel chatter or a lot push - try adding 5mm of sag in the rear.
I agree with the other guys...set sag first, ride it, and adjust from there. instead of moving one click at a time u might try what smrscott said and go full in on adjustment and adjust out from there depending on feel. I run a little less sag than the other posters but 100mm doesn't sound bad. if you get a lotta dive, add some more comp. and adjust rebound to suit; the suspension should rebound faster than it compresses.
Thank`s guys for all the tips, I rode the bike with 105mm sag, and 12mm on the forks, and fell good, but to tell you the truth, I don`t know what to expect, because I never rode pavement, I will try the 100mm sag and little more compression on forks, because feel that the go to far on travel.
