I know I'm gonna have people saying I don't need one but I want one. That said, doe anyone know a good spot to drill and tap a tell tale into this motor. It looks like there is an un-used boss on the starboard side just under the first coil and a little forward. But it is actually behind the head and I'm afraid I would be drilling into the cylinder if I went there. Is there a water jacket behind there or is it a straight shot to the cylinder?
