I think I'm going to test out a Buell 1125R - Page 12

Right on. I've added a half qt over 1500 miles.

The reason the xbs do consume oil is because of the expansion rates of the metal on start up.

If you ever see somebody start one up and get on the gas right away, it should blow black smoke a bit. After its warmed, it shouldn't happen.

I know it doesn't leak a drop. But it damn sure consumes. I just check often and add as necessary.

Does yours consume?

Mine used to when it wouldn't start properly. So, I'd have to hold the throttle a bit to get it to idle.

After I had the start up sorted out, I check it occasionally as opposed to every time I ride it.

Ya know they make a flat plastic thing to place under teh oil filter just for that. I have one at home... can order it from Drag's fatbook.

Aircooled engines run hot and therefore burn more oil. It ain't no thang. Same goes for the BMW aircooled flat twin.

Good info. Thanks. I know this sucker runs hot, that is a fact.

I'd like to see some numbers on the running temperatures.

I think the reason most air cooled engines feel so much hotter is because the heat is being dissipated between your legs. Whereas on a liquid cooled bike, the rad is placed away from you. This way you don't feel the heat transfer taking place.

I've always thought that the idea behind liquid cooling was to have a more consistent temperature throughout the entire engine allowing tolerances to be more exact which in turn would allow for a more powerful, efficient and reliable engine.

Water transfers heat at approximately 30 times the rate of air. But, at the same time your radiator is air cooled. I understand the concept that it's in an optimized position for air flow, the surface area of the cooling tubes is increased and the volume of water flowing through it definitely allow it to removed more heat than your typical air cooled engine. I would just like to know how much more, and what the average running temps are of air cooled vs liquid cooled bikes.
