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 The previous version was outdated and no longer supported.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

Time For New Drivetrain Parts

I got home from my weekend trip and went to lube my chain. Wow, the rear sprocket is destroyed. I have 3 broken teeth and the others are so thin I'm surprised they all didn't just shear off during my ride.

Does anyone have any suggestions for some good long lasting sprockets & chain that fit the 630? Bonus points if they come in red.

I'd prefer steel over aluminum for longevity purposes, unless there's something I don't know about some magical aluminum sprockets that are stronger than steel.

What size rear did you get - in the red 48 tooth is the smallest I see...

If you go down the page a little where it says "ON DEMAND CNC" on top of a gold sprocket, you can choose a red 42 in there. It's about an extra $30.

Here are a couple pics of the torn up OEM sprocket:

I replaced mine with a Supersprox - 44 tooth (I didn't want to go any smaller than 15 on the front). I removed the OEM one and was surprised it was made of aluminum. JTemple: how many miles did you have on the original?
 
That sprocket is in bad shape, how many miles? I see you have new parts on the way, but MotoXotica is a good place to go for the Husky special parts red sprockets. Did you get a red o-ring chain to? That sure is a nice looking combo.
 
Original stuff has about 9000 miles on it. I'm not disappointed with that. I think the chain I got is gold. Chain color isn't much of a concern as it'll be gooped up with lube all the time anyway. The new sprocket is a 2-piece deal from Supersprox that has a red AL center with black steel teeth.

I'm also replacing all the chain guide parts since they're all toast as well. What I really want is a BRP chain guide, so I'm trying to find out if their 610 version will fit. If it won't, I'll have to go OEM.
 
I bet the 610 guide will fit. Hopefully it does as it's a great piece of drivetrain compared to the stock crap my 2 bikes have come with.

Same here, 15 tooth in front promotes longer chain/sprocket life. But I do have some related questions.

The rear sprocket I want only comes in 41 or 45 teeth. If I keep stock 15 front and go 45 rear that gives me the gearing reduction I want. Actually 15/45 gearing would be identical to 14/42.

However I remember reading somewhere that it's not recommended to have the rear teeth evenly divisible by the front, i.e. 45/15=3.0 This would also apply to someone who dropped one tooth in front with stock rear, i.e. 42/14=3.0 Something about the same chain links matching up to the same sprocket teeth more often or less often? Is there any truth to this or is it only a wife's tale or superstition? If it is a problem then I guess I'll need to go 14/41. Not quite geared down as much as I wanted and will also get more wear from the smaller sprockets.

Secondly any idea if a 16 tooth CS will fit on the 630? If I go with 15/45 I might later on want to go back to stock gearing for a long road trip. 16/45 is near identical to stock 15/42 gearing. I do realize a longer chain might be required for 16/45 though. I don't pick up my bike until this Saturday otherwise I wouldn't need to ask this question. I really want to get the sprocket on order before then so I can swap out the stock aluminum sprocket and gear bike down as soon as possible.
