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 The previous version was outdated and no longer supported.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

2006 TE610 - No Spark

Searching for Ideas...

Brief history - Bike only has 4000 miles - Bought it off my brother who clearly didn't ride it much. Had it out on a dual sport ride and ended up with an undetected leak in a coolant hose which allowed the bike to overheat, which caused a head gasket leak, which pressurized the system keeping coolant in the overflow bottle, so the leak went undetected. Ended up overheating the bike enough to end up with two stuck exhaust valves - They didn't get bent, or contact the piston.


So, I had the top end rebuilt. After reassembly, the bike fired up and ran, although it didn't want to idle. Did a carb rebuild to check for any junk in the carb preventing the bike from idling. After reassembly, the bike fired and ran for a couple of minutes and then died. It will not restart.

It's not getting any spark at all...

I've replaced the plug... Nothing

I've checked the resistance of the coil and it falls within spec.

I've checked continuity between primary and secondary winding... it's there...

I've checked the 15 AMP fuse... It's good

Any ideas?
 
Check the condition of the plug cap and HT lead. Could be earthing someplace. Is the coil securely fitted and grounded? Check the pickup coil also.
 
Not sure if the pickup coil and CDI are the same thing but everytime I had a no spark condition on a carbed bike it was due to the CDI being dead.
 
Pulled the left side case this morning and it became painfully obvious why I wasn't getting any spark...

Something's missing here...

These do not look like they should...

Fortunately, Hall's had everything in stock and I should have the parts to complete the repair soon...

In all likelihood, when the coolant leak resulted in the overheating and the exhaust valves sticking, the heat probably caused the epoxy that holds the magnets to the flywheel to lose adhesion and the magnets came loose.
 
Made in China parts. Shouldn't have come apart like that even under those circumstances. Glad you got it sorted and hopefully the debris didn't make it through the engine!
 
According to Hall's... no updated stator available, although there is an aftermarket flywheel/rotor available if I wanted to upgrade. I'll take my chances with OEM replacements. Should be fine...

Pretty sure that the debris stayed contained inside the flywheel/rotor assembly, but I'll be able to tell more once the flywheel puller arrives with the parts and I pull it off. Obviously an oil change and filter replacement and screen filter cleaning will be in order and then another one fairly quickly just to be certain.

The top end was just gone through when the stuck exhaust valve issue was addressed. New rings installed, and the cylinder walls and piston were flawless. It only ran for a couple of minutes since that refresh, so it should be in good shape...

Parts arrive Friday, so I'll probably get it all installed on Saturday or Sunday. Hopefully we'll have some decent weather to be able to get out for a short blast after I get it back together. Not ready to admit that it's starting to look a lot like winter... Maybe if Santa brings me that Warm & Safe heated gear I've been hoping for, I'll get to extend the season a while longer...
 
The 2008 (or 2007) 610 and the 630 did get an updated flywheel and stator didn't it?
The magnets look different at least. And the stator cover is also different. The question is, are they interchangeable?

630/610 updated ------ 2005-2006 610
 
Should have clarified, Hall's said no upgraded stator available for the 2006.

Not sure that the FI flywheel will fit a carbed bike...
 
Stator assembly arrived on Friday and I got it installed when I got home from visiting family for Thanksgiving on Saturday night. Solved my issue. Bike fired right up... Now I just need to do a carb adjustment after the rebuild and all will be right with the world...
 
Glad you've fixed the bike!

I remember that, 9 years ago, when they released the EFI version of the 610, I read, on a magazine, that the alternator was more powerful because of the EFI. Therefore, I'm not surprised that the flywheel's different.
My EFI 610 doesn't have that caramel coloured sort of plastic. It's not the first time that it shatters in a carbed 610 and, according to someone who wrote that on forums, it's a dielectric material.
