  • 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 The previous version was outdated and no longer supported.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!

Gas tank breather line routing

My steering head bearings are really taking a washing from my tank breather line that is pointed down into the steering column. I really hope to stop this by rerouting the breather line.

Is there any chance the bike could catch fire from the hot exhaust pipe if the gas tank breather line was vented in such a way that gas was leaked on the pipe? I need to come up with something to stop the bearings wash but do not wanna start a fire.

You could try one of these vent cap check valves. Just be sure to keep it clean because if it clogs it will stop the fuel flow. They are available from a number of differnent places. http://www.mooseracing.com/products/?productGroupId=1477&productId=114728

Yep I had those but seem to loose them also ...It'll get super glued on if I ever get another one.

I need something for tomorrow ... I'm thinking I might just route a hose behind the number plate and put some foam over the end of the hose till I can get something better ..
 
That happens on my 630 as well. Now if you think thoroughly about the design of the bottom triple clamp/tube (that goes up and through the steering head of the frame) then there shouldn't be any way for gas to be washing grease form the bearings. Your vent hose is inside the inner tube of the assembly and that inner tube is truly separated from the bearings. That makes sense, but I still get the tell-tale streaking down the back of my front fender that tells me something is washing away, and that's not good.

Anyway, if you're just worried about the short -term then you don't have to have that hose pointed downward in a draining angle...it's to vent fumes/pressure so you could zip tie the end section up high, onto the bar clamps or something and pointed horizontal as gas won't come up that high. Conversely don't fill the tank quite as full, on mine that makes all of the difference between the puking of some gas and not.

I have one superglued on. Its been working well.
 
Get a long hose (same dia as oem vent hose) and route it all the way down under your engine, been doing that for years now. Cut end off on an angle and add a slit as weel, same for all vent drain lines to help prevent clogging at the ends.
I zip tie the loop to something up near the top and have the free loop going onto the cap, I always yank the tube then remove and reinstall the gas cap, even in qick pits.
 
You could safety wire the one way check valve. The hose being cut at a 45 and a slit up the middle is so it's harder to create a siphon.
