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 The previous version was outdated and no longer supported.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

Hey guys, I just bought an 08 smr450, great bike. The coolant resevoir cap has a small hole in it. it looks like maybe a vent hole or something along those lines. Im new to huskys so I dont know too much. However, every time I ride or transport the bike coolant seems to be spilling out of the hole a bit. Is this normal? or is there a way to stop it? many thanks for any help. :cheers:
 
The hole is for the pressure that escapes the radiator cap to come down and escape from the reserve bottle. I drilled the hole a tiny bit bigger on my cap so any pressure venting could happen a little easier. On my bike, that happened just a few days ago when I forgot to turn on my manual fan during some slow riding.

I don't run any coolant in the reserve tank. I run just enough coolant in the rads to cover the fins when the bike is on the sidestand. When hot, the coolant expands naturally and any excess will dribble into the reserve bottle.

Try this: empty the reserve bottle and then check the level in your rads. Go riding and if any coolant comes out of the bottle, you may have a bad rad cap or an overheating problem.
