Thanks, that will help me mark the clear tube I have going to the tank. It won't work to mark the tank since it's solid SS(see picture), but I used a clear plastic tube purposely to allow viewing of the coolan level. Thanks again.

You can see the overflow mounted on the downtube next to the radiator. With the clear plastic feeder tube it works good for checking coolant level in the tank. With that unprotected seatpan it reminds me of my HS days riding a hardtail. First time out with no foam, it was "crunch" time when I went out the driveway. A couple times like that will make Glen Campbell sound like a bass compared to you.
