[QUOTE="TravisCR500R, post: 239719, member: 22382"] [b]Don't scribe!~!![/b] Dont "scribe" the piston! It will scratch the side of the piston and wear out the cylinder quicker! Instead: use stuff called "dykem" its a machinists blue...you can get the spray stuff or use the paste...or take a black marker and "color" the area on the piston...the area inbetween the "color" or dykem (if you choose to use that) will be the area you should drill your holes. Would you run sandpaper on the side of a new piston before putting it in your cylinder? I think not! Do be sure to deburr the holes...they will create a hot spot if you dont. Travis R. [/QUOTE]
