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 The previous version was outdated and no longer supported.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

Spark but no start

Yesterday a rare problem happened, the engine cut out whilst I was riding (luckily on a play area so no traffic) and the bike would not start anymore.

Since getting the bike recovered I have tested for a spark and thus far every time I have tested there has been a solid spark white coming through.

But the bike still won't start.

Here is a video if you don't believe me:



I have pulled the carb and checked it and half heartedly cleaned it since it was so clean anyway I knew it wasn't needed.

The recovery mechanic suggested it was the ignition coil but in January the ignition coil failed and I replaced it with a new one from Husqvarna so the coil is only 8 months and 1600 miles in.

So if I am getting a spark, fuel and air is it possible the ignition coil is still at fault but in another way? I am hoping the CDI isn't shot but then it wouldn't be sparking at all would it?

I have measured the resistance of the ignition coil like this

And without the cap

Are those readings nominal?

What could cause a no start with a spark? The comp is fine, it's getting air, fuel as the plug is wet when I pull it after starting attempts.
 
My friend check your compression and that the spark is at the TDC the compression is the easiest one.. If you don't have enough compression could be a scorched valve or just closed valve clearence.
 
Figured out why. This was stuck to the pickup coil and throwing the spark timing off

Any idea what it could be a piece of? I was thinking guide blade but it's metal coated with plastic. As far as I am aware the guide blades are just plastic aren't they?
