i have a 200 blaster and it has a knock in the engine someone told me rod bearings.does anyone know what it is?

 

is the knock in the head of the engine? put a glove on and place your hand on the cylinder of the engine. if thats where the knock is comeing from time for a new piston+rings and an overboar job. if it has been a couple years of rideing since you last rebuild its time for one

 

well i have only had it like a month and the guy i bought it from said the whole thing was just rebuilt and it had only like 3hrs on the rebuild

 

thats not good... im not an expert on 2strokes. but usually when they make noises its rebuild time

 

it seems to run just fine though so i dont know
