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 The previous version was outdated and no longer supported.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

SM610 Cold Starting Issues?

Hi All

Not sure if I have an issue or not so I just wanted to ask the group - Are these FI SM610s cold blooded?

Background:
I got a 2008 SM610 last fall that was non-running. I fixed a host of electrical issues and had it running last fall. It seemed to run strong although I didnt run it long. I know they can be noisy motors, but I thought I heard a ticking sound so I checked the valves. Im 99% sure I was at TDC compression and found the front valves to have a huge clearance - something like .080". It was so much that the little swivel cap on the end of the rocker could almost come off. I figured that was the source of my ticking, so I adjusted to the spec .002". The rears were measuring right at .002".

Fast forward to now, I put the bike back together yesterday and tried to start it up without much luck. It turns over fine and seems to pop and fire every now and again, but just doesnt take off. If I open the throttle a bit while it's cranking it will fire and run for a second until I leg go of the throttle.

It's about 30F here right now. With that thick oil in there are is it just too cold to start? Did I somehow muck up the exhaust valves? Note I tried the little enrichener lever on the clutch handle with no change. I did a compression and leak-down test prior to starting any work on this bike and it checked out great. Seems like I still have spark so I guess im down to valve issues or just being a cold blooded monster.

Since I didnt intend to ride I didnt work very hard to get it to stay running - figured I'd ask here first.

Thanks!
