  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Te511 oil shower

Been awhile since I have done anything with AN, NPT sizing and found this page to be a helpful brush up. http://aeromotiveinc.com/2010/01/an-vs-npt/

Basically 1/4"NPT out of the oil return/tapped filler plug, to 6AN straight fitting, then a 6AN swivel fitting to run 3/8" hose to a bottle or tee fitting.

Hey Tinken, the bottle kit is supposed to come with the fill cap right? Can I buy separately for the same price, since it sounds like the bottle is a ways out?

That is what I am thinking of doing. Ty was thinking about actually making this fitting, but this is a good design and might not have to be reinvented.

You can go ahead and pick up a fill cap now. We haven't decided what is going to be in the kit, but we might sell one as just the bottle and one as a kit so that people have more options.

I plan on doing this mod myself however the only concern I have is that wont the oil filler return mod also become a breather vent as well?? So instead of the oil returning to the crank case from the Zip ty's breather vent it cant because pressure is coming out of the oil return. I could be completely wrong and have no where near as much knowledge as people like tinken but thinking logically wouldn't this be the case??
Im hoping tinken and a few others that have a lot more experience maybe be able to shed a bit of light on this.....

Absolutely would be the case :cheers: What will happen is the gasses will find a check valve after going out the filler and will be stopped in there tracks :thumbsup: I have thought of every single way to do this :lol: The way I did mine is ran the oil return line bellow the clutch cover so the line loads up with oil to block the gasses, there isnt that much psi in the case as long as the vents are working good, like less than 1 lb.

Did you actually add a check valve to the hose line or is running the hose under the clutch cover your version of a check valve?
 
My original breather bottle had a check valve, but I removed it because it didn't make any difference and it impeded flow back. In my new breather bottle coming, it doesn't make any difference whether the gasses flow up from the vent or the oil drain.

I tossed the breather box for a radiator reservoir and a auto chain lube system.... still needs testing.... My breather can worked great but I wanted more.

I knew that was comming ! Ha ha let's see what I come up with, bike will be down for a bit . I might parallel two lithium batts and install a 12v cigaret lighter when I get to electrical :)
 
Just a thought , what if I were to strip off the red powdercoat on the valve cover , weld an AN bung on and red anodize the whole thing ? Were is the best spot to put the bung ? I haven't taken the cover off yet to case this mod. :)
 
The valve cover is magnesium and difficult to weld, the reason behind us not welding them. There are no good spots on the valve cover. You would have to build up a ridiculous amount of material on one of the rounded surfaces and then weld to that spot. The time and money involved to add a clearance free mount exceeds the cost of our mod, which is why we made a lot of them to cover the ridiculous time into the project. :)

I wondered about this, but a couple of other guys on here had run similar set ups without issue. No issues for me with 1200cc of oil. This is where the breather bottle will complete the design mod correctly. And act as a cooler to some effect.

I ran clear tubing up to the airbox, thinking that I would run a few tests and possibly see some oil build up. My first test was 70mph (with stock gearing) for 3 to 4 minutes, followed by about a minute of riding in circles with some simultaneous brake and clutch play -no visible oil. Next test was a 1/4 mile or about 800' of sustained hill climb -no visible oil. Last week I had two 'lazy bike' incidents while trail riding, where the bike was on its side for about 5 seconds -no oil on the left side, little oil wash evidence in the clear tube when it was down on the right side, but no sitting oil.
 
when the oil fills the torque limiter holes, then the oil really starts coming, its like a siphon.

Yeah, I haven't tried more than 1200cc, but do remember Rear's oil experiment videos. I though I would have seen some oil build up at the top of the hill climb...
