ok, i got a 1994 yamaha blaster with 240 bbk in it. the kickstart lever wont go down to turn the engine. and i took the cylinder off and tried pulling on the piston and pushing on it and it wudnt budge. ive been told its a rod bearing or crankshaft bearing. can anyone help me out on wat it is? i dont have money to throw around on parts i dont need and want to get it going
