I have just replaced the pistons on my banshee to one size over, and bored the cylinders, do i need to have it re-jetted??? what is the oil ratio premix i should use with this new top end? and finally what is the breaking procedure if anybody knows? thanks for ur help....

I AM REPLACING A CRANK, CYLINDER, AND PISTON ON MY BANSHEE AND I DO NOT KNOW IF THIS ENGINE HAS EVER BEEN BORED. I DO SEE A NUMBER 200 ON TOP OF THE PISTONS, DOES THAT MEAN THAT IT IS BORED? AND IS NOT A .020 NUMBER, I AM POSITIVE THAT IT IS A 200 NUMBER ON TOP OF PISTON. ANY HELP WILL BE APPRECIATED SO I CAN ORDER THE CORRECT PARTS. THANKS..
