could someone give me valve clearance, carb adjustment and plug gap for this model. im tuning it up for a friend, but have no manual.

 

Do you mean a 250sx? I have a 200sx quad and here is the information you need for the 200cc "the valve clearence for both the intake and exhaust valve is 0.08 mm", the plug gap is 0.6-0.7 mm, what do you need to know about the carb?
