i'll get some pics of the tank when i go to the shop

btw, i didn't fill anything on my motor. the side covers are REAL thick, i just sanded the cover until it didn't say yamaha any more. i get people all day long now trying to guess what it is, lol.
you must have a newer motor (mines a 74) as the older ones don't have a sight glass, just a regular dipstick.
