I almost hated to ask but you know what they say, "the dumbest question is the one that doesn't get asked." Hate to have a disaster. I'm removing all water hoses. Coolant is drained. I'm down to the last two hoses on the oil cooler. Can I just unclamp and pull them off or will I have an oil spill? These are just water hoses, right? No chance of contaminating the oil?

---

Correct. You are looking at two coolers in one. Oil is separate from the water. Think about this. I have no clue what art is, but I know what I like when I see it. With that said, my eye darts around the bike, first thing I see is how did that finish off, was that hose statement.

My take is the bike will look unfinished, not finished off. Why stop at the water hoses coming off the radiator? Finish it off with both oil bends. Call hoseman and suggest the comment made. I suggest they keep hosing or I see it as, 'ah man, they shoulda, look at that, I don't know? Do you see it?'

---

Mate, I'm 99% sure they're all coolant hoses on the #9s. If that lower hose was oil, there'd be a return hose down there too. The manual confirms in the Engine Lubrication System - page 7-16. Item "D" that you're referring to states both hoses going to the cooler are "water hoses". Go for it.

---

Oil spill, yes.

Here's what you do. Finding a clear hose like the bulk at homedep for fridge water say, and say we are looking at inches over mm diameters. Either it fits too tight and that's a good thing or slips over and now hose clamp it down to stop any leak. Have the hose higher than the crankcase oil level so it obviously can't climb to get out. Cover the hose end with a wine cork cut down, I'm imagining the diameter of the cork would work.

Pg. 7-4 Oil Path

See the gray parts say oil?
See the arrows say path thru oil?

See bolt 5 with circle around the number? See the circle with the S letter in it? I believe those are oil lines out of the oil cooler housing.

yeah, I saw a diagram showing the coolant circulation and both contain coolant. Just thought I better ask. I'll pull them.

Oh, I see it. It's up to Samco what hoses they want to include in the set but they'll want have all from me. I think they will make the oil cooler hoses as a part of the set. I was told Samco will include the the small diameter hoses in the set and the oil coolers are bigger hoses. I think they will do the whole 9 yards. Everything that holds coolant.

I'll ask them to include some of their straight vacuum hose for the drain tubes on the left side. That would finish off the hoses very nicely.

So I pull off the oil cooler hoses tomorrow. Still have to take oft the small hose behind the water pump, too. Need to remove the sprocket cover to get that one out nice and clean. This is definitely the most pieces the bike has ever been in.

Maybe it's the way I'm seeing it, not to dispute your knowledge Hub, but that oil path is from the oil hose/rail which enters adjacent to the filter and cooler beneath the cooler. The water hoses enter via the cooler body. Pages 7-6, 7-11 & 7-16 show that more clearly.
Bolt 5 on your cooling diagram are cooler body bolts. 4 of which have to be tightened in "S"equence.

A good idea but I would loose some oil before I could get the stopper hose on there. I don't think it will be necessary though.

Yes, the oil cooler is shown as a part containing oil. But it contains coolant as well.

See bolt 5 with circle around the number? See the circle with the S letter in it? I believe those are oil lines out of the oil cooler housing.

Bolt 5 is a mounting bolt for the OC. "S" means follow specific tightening sequence. No way those are oil lines out of the housing. P 4-4, OIL COOLER, Outlet hose (to rad), Inlet hose (from the T in water pump outlet to engine/ oil cooler). Both of those oil cooler lines have to contain coolant. Also, if it was an oil line, they would not use just a hose clamp, there'd be a permanently affixed connector of some kind, I'd think.

I think I'm clear to pull those oil cooler hoses, hey?

That has to be right. The oil cooler contains both oil and coolant. They can't go into the same chamber or they'd mix and you'd have oil in your coolant and coolant in your oil. The oil cooler must have a chamber that surounds a separate chamber for the hot oil. If the hoses are pulled no oil will come out. Maybe a bit of coolant will.

---

You're on the same path as I am now Rook. Send the dogs out and pull the hoses.

---

Sweet, you are correct. Pg. 4-4 pointed it out. My apologies for that moment I want to buy a lotto ticket, I had some instinct about this. I've never torn down bullet so that was an assumption on me and how they cool that oil deal.

---

1 AM here, fellas. Time to hit the hay. Off to work a little later in the AM. Then we pull the rest of those hoses and send off to Samco. Might be international shipping. About $60. Maybe I can get them to pick up the tab on that one.

Thanks for helping me figure this out for sure, guys.

No probs Hub. We're all here to help out and discuss yes? How cool is it when you have help that's working the problem through together, to a rapid conclusion all at the right time.

Last bike I recall was a late model suz 1000. And now I recall, those suz lines had the same old line fittings from the cb750 honda. And if the kawi brand uses this water to oil approach, how clever is that idea? Don't get old! Oh, I'll have more of those seen your moments.

---

how clever is that idea?

It's a good idea. I wonder how much dif it makes though? Some turbo 14s need to relocate the oil cooler. Muzzy or someone makes a relocator bracket. If I'm not mistaken, I think I recall hearing that some owners removed the oil cooler all together? Eh, I'd have to research that a lot before I ever tried it. The busa has a small oil radiator to cool oil. It works just like a coolant radiator. Oil in, heat dissipates through fins, fins radiate heat off into the wind. I'm giuessing these bikes need something to help cool oil. Sure like to try dropping the few pounds of oil cooler though. But then I'd have to give up 2 of my Samco hoses.

---

Had a 2"(?) hunk of aluminum tube stock, glued the thing in front of the oil cooler. Lets put it this way, it didn't change a bar on the dash.

... owners removed the oil cooler all together? Eh, I'd have to research that...

1) Faster oil pressure. 2) Less weight to compensate (ounces add up). 3) I don't hear turbo's cooking the 14.

Sure like to try dropping the few pounds of oil cooler though. But then I'd have to give up 2 of my Samco hoses.

Stay stock. Whatever you think that thing looks like it weighs, See this?

---

The oil cooler might just even the weight loss off to -100 lbs. A pound here, an few ounces there....it all ads up. I'll try the oil cooler block off some day if I hear others have had good luck running without one.
