What if you lay the bike over? I know that we don't like to think about that, but If you laid the bike down on the crash bar and it split or kinked?

Just like every other part that gets broken, from a crash or whatever, you fix that part also...

Those crash bars are strong. If you break it enough for oil to leak, that will likely be the least of your problems.

Moving to Vegas sure seems like it would justify a real oil cooler.

If the crash bar was any kind of effective, HD would have done it years ago.

I would agree with you if it didn't work really well. But it does, or at least it did in my experience. As I mentioned in one of my earlier posts, the bar got so hot it melted some of the paint on my lower. So I wrapped that small portion, NOT the whole crash bar, but ONLY that small portion that contacted the lower. And since the bar got HOT enough to make the paint go soft, I know it's doing it's job dissapating heat. And while the bar does not have radiator fins on it, I see it as the WHOLE thing as one giant fin dissapating heat. Since the inlet side is hotter than the outlet side, I know the oil is being cooled off as it courses through the crash bar. And sitting on the strip in Vegas is where I really saw the difference.

From reading some of the posts here it's plain to see that the HD oil cooler is NOT for everybody. Those who wish to only run a traditional oil cooler are more than welcome to. But having run both, in my experience I have to say that both work well.

Excellent question. As Beary pointed out the crash bar is quite rugged and can take quite a beating. But IF it were to start leaking than bypass it. Carry a small connecter and just hook the hoses together. However in my experience, and from what I have read from others, the real danger from leakage comes from the hose clamps, not the bar.

One think I liked about the crash bar over the traditional low mount oil cooler is ground clearance. Being able to ride up and down curbs and sidewalks without fear of smacking the low hanging oil cooler on the curb was a plus for me.

I would bet that the crash bar has more metal than the oil cooler's fins, however we could add more metal for cooling like highway pegs, lights, cup holders and even that dead cat that was hit awhile back.

.......OK, maybe not the cat.

Hot on the inlet and cooler on the other end.
Sure does sound like it is doing what you want it to.

Interesting.

This is an old mod I'm glad to see renewed. Ya just gotta be sure that bar is absolutely clean and dry. And any worries about rupturing it? You'll bust your own guts open before that thing ever cracks. It'll scratch and bend but unless you're in a violent crash it'll be just fine.

I was thinking about Kreeming the inside of the crash bar. http://www.bikebandit.com/kreem-tank...LAID=338724069

Stuff works great in old rusty gas tanks. Just a thought, might just flush it out though.
