HI all. May be a stupid quetion but, I bought a CT 175 not sure the year, aparently got some parts from a CT1 but there are parts form ct2 and Ct3. The engine come all in parts. The head of the engine got 2 spark plugs, Is that normal for a 2 stroke bike? Should it has only 1 spark plug as it has only one piston? Try to work my head around.. Thanks . John Pyles
