The carb should be left alone - the speed of the closing of the valve has no influence on the air-fuel mixture. Just back the adjuster out one turn , with a fine adjustment later- that should be enough.

Hi.

Problems with leaking gaskets are usually due to incorrectly torqued head bolts.First make sure that you have used enough torque and that you have replaced the screws. The screws must be replaced along with the gasket. The screws are Torx 25. Also use Antiseize Compound.

If you have replaced only the gasket you may need to replace the control cover and screws as well. The right side control cover is part 5483700700015. Here the cover: KTMWorld - KTM Parts - CONTROL COVER R/S.
The screws p.n. is 58605083014. Get three new screws and follow procedure when replacing the gasket. See: KTM SCREW M5X14 TORX 25 07

Here replacement procedure:

The new nuts and washers must be lubricated with anti-seize compound at the threads and contact surfaces. First tighten the nuts without reaching the full torque and then tighten again to reach final torque following the same pattern (the screws are torx 25 07. If you tighten them over the max torque you need to replace the parts again).

Here parts manual for this bike.

Regards.

SOURCE: getting torque from ktm 200 xc

Vance,
Thank you for contacting FixYa with your inquiry. I have been going over some of the older help requests that have been archived and
trying to provide solutions for those that didn't get answered. Hope
this information helps.

The simplest way to build torque is a trade out increasing gear ratio for speed. Go up a tooth on your rear sprocket.
That being said, I'm sure you want more beans out of your engine. Jetting has a huge effect at high altitudes (riding in the mountains). On the more expensive side you can purchase 3rd party pipes that change the power band, you can, do some flowing on the ports and removing material raising the exhaust port to make a huge difference. Cleaning the carbon buildup out of the port adjust system might help as well.
"If your a fat guy like me, a weight loss program could take as much as 25 lbs off the bike and the need for torque decreases some".
Depending on the bikes age, you might want to trade up to to a 300 or 350 where you have more torque and six speeds using the speed ranges in the transmission while not loosing top end. Have fun and keep the wire tight.
