Just got this and it’s in really good shape for the year but the oil temp light comes on as soon as I turn the key on and doesn’t turn off any ideas where to start will be appreciated

You can check the oil temp sensor using a multimeter set on resistance mode. The sensor should measure between 9.5k - 10.5k Ohms at room temp (25 degrees C, 77 degrees F). It sounds like yours is shorted, so check the wiring and harness plugs first for a short to ground.
