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 The previous version was outdated and no longer supported.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

2007 smr 510 runs great then dies when hot.

Okay so as my title says, I have an 07 smr 510 and it runs great but always has a dry black spark plug but when it warms up and Gets hot after I give it full throttle it immediately just quits and needs a few minutes to cool down before I can start it again and usually I have to jump it with jumper cables even with a new battery. I've had the coil tested and they said it was fine but they never tested it with heat on it and I don't know how to test the coil or cdi or stator or voltage regulator. Any guidance would be fantastic, I have a new coil and cdi on the way but they're on back order and won't be here for a few weeks. Any input is very much appreciated.

Dry, black plug means too rich. A bike needs less and less gas as it gets hotter, yours sounds like the choke/fuel enrichment is stuck open, bike is jetted too rich, someone has tried to clean the jets with steel wire and enlarged the holes, making it too rich.

Hey Nignog did you fix your problem with new regulator?

No, my new cdi comes in today actually, the regulator doesnt have anything to do with spark, you can unplug your regulator and still get spark. If the new ecu doesnt work, the last thing I am going to try is a new stator. Ill let you know how it goes tonight.

Here too, I think. Just too busy to fix it. Easier to ride my spare bike which I recently replaced with a new one.

Right? I'm grateful that I have my Victory Vision to keep me on 2s, and have my 2 track bikes to give me my speed fix. But I really want this sorted. I was left stranded on the way home from work today. No bueno.
 
I had the same issue with one my bike when got hot she died, turned out i needed a new coil. New coil fitted problem solved.
 
SOUNDS LIKE PULSER,WE FOUND A REPLACMENT WITH MINOR MODS WORKS FINE $74.95 INSTEAD OF BUYING ENTIRE STATOR,CHECK YOU PULSER FOR A PULSE WITH ANALOG METER WHEN SPARK GOES AWAY.
 
I had a similar problem with the motors 450 08 and ' 09. after half an hour started misfiring, had to keep the revs above 3K for it to work. I changed each of the components - stator, choke, pump, coil.. the reason was simple. all my recent spark plug cr8 copper (5 pieces) was defective. put the old spark 8iex and motors work perfectly
