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 The previous version was outdated and no longer supported.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

Engine breather, '09 SMR510

Hi All

Thought I would share with you my installation of an engine breather on my SMR. Rather than the vent hose running to the after filter side of the engine air/fuel intake (and sucking in gummy hot oil vapours) it vents independently. The K&N filter sits next to it's bigger cousin via a 10mm hole and a coupling tube through the plastic plate. The breather entry to the inlet has been blocked with an alloy blanking plug. So she's only breathing air/fuel

Nice mod man...Just did the same to my TE 610ie last weekend.No more oily and hot fumes sucked from the intake...Cheers....
 
I was just messing with this the other day. I routed the hose up towards the neck of the frame. So any oil vapors will condensate and run back down the hose and into the head if possible. I was also thinking of putting a check valve in towards the top so that only Positive pressure from the engine can vent, but the atosphere (Rain/dirt) cant get in..

But I like your Idea. I dunno which is better though. Anyone have any good,extensive knowledge on the matter?
 
Hi JR. I kind of went on the principle that it only vents to the intake for emissions regs. And the intake actively sucks, not a neutral air zone. I do prob 2k a year max so no real issue to 'global warming' going on here. My older 4 strokes always ran a crank breather with no valve, just routed upwards slightly to fresh air, often from the oil filler neck, not even a breather and they all got ridden hard and owned for years at a time. A lot of crank vents do vent from low down so there should be high pressured oil splash here, just the hot fumes. Which I guess will always run back toward the exit point as you say as it sits lower than the vent. I think re the check valve also, the engine 'sucks and blows' (missus!), so a one way might cause probs? If anyone else has any thoughts throw them in
