OK, I'm going to go stand in the corner for awhile. Hooked up Tune Ecu. Had a code for the temp sensor, which (I fixed, by finding the plug for it), and had error on coils 2 and 3, from when I fired it up with only number one coil connected. Funny, idled fine on one cylinder! Anyhow, cleared the error codes. THEN discovered I was looking at the wrong light bulb! I know, I know. Poor old eyes going to hades, even with reading glasses on. So sad. I was seeing the engine light, thought it was the oil light. Sorry Guy's for the bother. All appaears to be well now. Tomorrow will put the radiator on, try to find the fan socket, and run her some more before I start re-assembling the swing arm, wheel, etc. etc. as a consolation prize, I'll get some video tomorrow. Hope it makes up for my stupidity. Sorry, sorry, sorry.
