Coolant overflow tank

So the stock coolant overflow tank interfered with the idle speed screw, float bowel drain screw, and the choke on the Mikuni TM33 I mounted on my KLR250.
I made a new, smaller tank from a baby bottle (clear and heat resistant). Now I can drain the float bowl, reach the idle screw and it looks like I can fit the carb mounted choke plunger. Right now the baby bottle is zip tied to the frame. If it seems to work, I'll work out a better mount.
I drilled two holes through the baby bottle flat storage top, epoxied a couple hose barbs in the holes. One of the barbs has a hose inside the bottle that hooks to the radiator tube, the othe barb hooks outside the bottle to the vent tube that goes to the rear fender. The baby bottle nipple flange is being used as a gasket.

I think it will work. If it warms up a little next week I'll get some more riding in with the new carb and catch tank.
