Im in eastern/central Ohio. Took the bike out for the 1st time. I havent ridden since 98. My last bike was an 85 CR 500. I know suspension has changed ALOT from that bike. But I have to figure something out on this GasGas because it is no fun! lol. I went for a ride and the front end felt like I was riding on marbles. No i havent done anything with sag or any personal setup yet, but jeeez I almost dont know where to start with the front end.

Start with servicing the suspension and getting proper springs for your weight. Then set your sag. Adjust all clickers to their mid point and locate the forks at the stock height. Then ride it, see how it does, and adjust from there.
 
I did all that to the suspension today. seemed like front was 26 clicks rebound/comp and rear was 26 rebound, but damn i counted like 70 clicks on the compression. I think the rear has the high/low speed adjustment with the 17mm nut and screw inside of it. I read post here about setup, but front was for Marzochs, I have the Ohlins. But, i found out that one of the bike previous owners has a suspension shop and he races GNCC, so maybe there are heavier springs in there. Waiting on phone call back to see if he remembers the bike. Anyway, also going to get different front tire, Magnum ex on there now, and push forks all way up in trees. Theyre about 12mm up right now.
 
You don't know how many hours are on the suspension or the spring weight? Without knowing that all other adjustments are pretty much worthless. Everything starts with that. Get it serviced. Suspension should be freshened up (new fluid, possibly seals and bushings) about every 40 hours of ride time or once a year. Also, while having that done have the springs checked to see if they are right for your weight. Any shop worth dealing with can tell you what springs you have in there once they get them apart.
 
Replace jet block o ring .Always a cause of bad idling and shitty running.No amount o jetting will overcome this You need to do a plug chop to get an accurate plug reading. 40 or 42 pilot .Throw away original needle ,try the Suzuki rm 250 and 180 main AFTER you check /replace O ring .Good luck
