Actually the water cooling keeps it cooler longer... and no, it's not the same temperature for both cylinders. The rear one will always be warmer because the front one always has more fresh air flowing over it. I agree with KingRobb. A friend of mine just recently rode her 30,000 mile on her Road King and STILL has yet to have the temp light come on. Especially with the new Evolution motor Harley has just come out with. And, although my bike is liquid cooled, it's always running out of coolant, which is a pain in the butt to refill! Ah well! C'est la vie!

And the two outside cylinders on a liquid cooled inline four also run hotter. What's your point?MotoF150 wrote:as an air cooled engine, ask any guy that owns a HD, as long as ur moving with a constant air flow the engine will stay cool, the V twin engine is a poor design to be air cooled, while ur moving, the front cyl gets the cooling air flow and the rear cyl gets none, and ask any HD Mechanic and he will tell you the rear cyl will wear and fail before the front cyl does. On a water cooled engine its two-fold, the water cooling works to warm up the engine quicker so it runs more efficient, and ALL parts of the engine are kept and controled at the same TEMP. water cooled is better!
This should be accounted for when the carbs are synced. But you're such an amazing mechanic you'd know not only why but how.
Of course I'm generalizing from a single example here, but everyone does that. At least I do.
