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 The previous version was outdated and no longer supported.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

Rear sprocket wear

I just replaced my rear sprocket and noticed this wear only on the spoke side. What is the problem and how do I fix it so I don't wreck my new IronMan sproket?

I would check to see if the chain guide is feeding the chain on so that it is centered on the sprocket. I have seen the chain guide lugs on the swing arm bent or not welded on correctly to begin with.
Look/sight down the bottom side of the rear sprocket and see if it is centered in the guide.
 
Tie a long line of some sort around the rear tire in back and hold the lines while standing in front and sighting down them. You want to keep the line just touching the back and front of the sidewall (or a 2x4 etc...). See how the front lines up.

Your issue though is rear sprocket and countershaft so I'd see how the sprockets align with a straightedge. Could be adjuster marks are off and then the guide.
 
Motion Pro makes an effective and inexpensive alignment tool. Works great and very simple. Adjust your chain tension and wheel alignment as normal, putting the axle nut on hand-tight. Then attach the MP tool and kneeling behind the spocket side of rear wheel make micro-adjustments to the axle blocks until the Rear & CS sprockets are perfectly aligned.

Unfortunately the swingarm & axle block reference marks simply aren't accurate enough to align the sprockets reliably - most will get you in the ballpark but your driveline components will last much longer and your bike will perform better if you take the time to do it properly.

As Excuvator mentioned, make sure your lower chain guide (that guides chain onto rear sprocket) isn't excessively worn of has been bumped out of alignment. If still using the OEM chain guide replacing it with one made by TM Designworks is a great upgrade. Good luck.

I have the same tool, works great and is less than $20. Highly recommend it.
