Plans: 1: Continue incorporation of engine upgrades for additional cooling. Status: Complete. The three cooling mods were installed: header tape, blower fan with coolant sender and vents. Also, it was noticed that the overflow bottle for the radiator failed at some point. The cap cracked and is now insecure. The engine cannot be run in this condiotion. so I looked online for a replacement cap. None was found. You need to buy a complete bottle assembly to get the cap. The bottle did not appear to be available direct from Aeromomentum anymore so I continued to look elsewhere. Ebay had them. The bottle was replaced.
