I have done the search thing but is not successfully on the info, and are more confused now. I need info on jetting and maintenance for my 92 KDx125, but found zilts/non under the search function. Then tried only 125 but found that the KX and KDx is not similar engines, or are they? And what's the difference? In South Africa the Kx is not being sold, so my search on that will also not help. If possible someone can direct me in the right direction.
