My old coolant tube that wraps around the front of the engine was in sad shape, so I had a new one made in SS (if anyone needs one, I can refer you to the shop that did mine $218). My question is mostly about the smaller heater hoses. 898 doesn't have any "Y" pieces that I have seen on others, just a pair of shut off valves going to the heater core. Is that a design evolution or an improper modification in years past? If that is the case, is it causing a restriction or problem if the heater valves are closed?
I've read the "proper" valves are shared with an Alfa, anyone know that model or part #?
Here are pics of the new downpipe and 898's arrangement for reference
