Boxer 427 over heating?

[rack]

So I bought a boxer 427 and love it, only thing is it seems to be running really hot (it was 90 today), is there anything that can be done to lower the operating temp? Or any aftermarket warning lights I could install?

I feel like the biggest thing would be moving the muffler outside of the unit and mounting it on the side if that is possible.
Thanks

I had a TL224 and the fuel would boil out the tank when you took the cap off. The muffler end blew out and I put a header together and moved it outside the body and solved the problem with a tractor supply muffler for $30. Ran better too
