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 The previous version was outdated and no longer supported.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

If in boudt check your TDC relative to the timing mark the you use to set your timing.. Im guessing it is your stator windings are fried. They don't last forever... I did mine twice on the 570. Once when new and 4 yrs later.
 
Thanks man, i have a puller coming in the mail from England so when it arrives I will look at the key and check the damage. The part appears to be around £2 or so, so hopefully this is the issue.

I've learned a lot about my bike through this problem.

Good suggestion.

but his bike was running just fine til he stalled it which is what makes me think the woodruff key sheared. He has good spark.
 
Is there a method to get the flywheel nut off of the rotating casing without using a flywheel tool? I dont have that particular tool.

I'm hoping the solution is evident when the casing comes off be it stator, woodruff key or magnets.

Gotta thank you all for the help, i'd've never got this far without it.

impact gun.

you will need some way to hold it while torquing it when you put it back on though. Strap wrench will work in a pinch.

If you can get hold of some 6~8mm rod. Put a bend at about 15 mm down @90deg. Now measure from the hole in the flywheel to the footpeg. Put another 90deg bend so that it picks up on mounting bracket. This will allow you can anchor it down then undo the nut. From there buy a puller off eBay.
 
Nice suggestion man, i have a puller coming from eBay and I managed to undo the nut using some mole grips. I'll post up my findings when the puller comes.
 
So this is how the cover aligns with TDC, with the mark aligning with the bolthole. I cant check if the magnets have slipped or the woodruff key until the cover can come off.

Can i do anything more to diagnose?

So got the flywheel off and the magnets were loose as hookers. Been looking at realigning them. Ive been reading the primary magnet should sit at 10 degrees btdc.

Where should the 10 degrees align to, is it the woodruff key slot which aligns with the stator at 12oclock or is it the mark on the flywheel case about 90 degrees forward?

There is a slot on the crank and one in the flywheel. There is no way to get it wrong.
 
Absolutely, this is at 12 oclock or thereabouts when my engine is TDC. Should i mark my 10 degrees before this? Or before the mark that seems to be on the flywheel case you can see in the above picture that aligns with the bolt.
 
Ok so i got the bike going with timing 10 degrees from the top and centre of the flywheel as you look at the back of the flywheel, so one oclock as you face it.

This image helped me where you can see the flywheel key slot which also aligns to 12oclock when TDC. The other arrow is a primary magnet dimple on a new flywheel assembly for my bike.

Thanks to everyone that helped me along the way, its been educational.

The timing is important to the cam angle. The timing is set BTDC. Before top dead center. If you have moved the magnet position relative to the stator you could have problems excessive retardation or advance. You need to check using electronic metering.. also keeping the magnets in check is important. Pinning then to the flywheel is the best way.
 
Thanks, I epoxies the shit out of those magnets and tuned the timing by the Allan screws that holds the stator on. I was getting a little idling problems initially but once tuned using this method she sings and kicks on the first kick. High revs are fine also. :-)
