i have a skyhawk gt5 66cc with cns carb . i have the oversized billet intake with after market air filter. bike runs great up to about 25 mph then starts to "4 stroke" on and off . my spark plug looks text book coco color and everything is tightened down nicely. it never did this till recently when i put a new carb on (last one broke) . acceleration is good but no top speed without serious vibrations. also should i be greasing up anything with some serious grease like the drive sprocket?
