Hey C moto people! Compliments of the new year, may you prosper ever more!

Ok, so now back to my problem. I recently bought myself a xmas prezzie in the form of a performance exhaust. All good besides the difficulty in idling and slight popping sound when I release the throttle while slowing down. Performance overall is deffinitely better than I had with the stock exhaust. Sounds great too! However I suspect my bike is running too lean so heres my question..

Which direction do I turn the air screw, clockwise or anti-clockwise. Thus far I have fiddled a bit with both directions and so far it seems slightly better. However I dont know if its because its now leaner or richer that has done it.

Please help!

My ride is the Loncin Jedi 250
