You can also do without. Honda thought so.
Honda also thought to do without making the engine 836cc with a big cam and a custom oil tank. And, had they included a $767 gauge that has a temp reading then they surly would have hooked it up with a $3 connector.
Put mine in the oil pan drain plug...that's where the oil drops after heating up before returning to the tank. Daytona makes all sorts of bolts that allow it
Thank you for that useful post! I will try this if my current solution doesn't work out.
Cheers.
