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 The previous version was outdated and no longer supported.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

CHAIN PROBLEM

Hi, having just fitted new sprockets on my 511,a 14 front and a 53 Supersprox rear, with a new 520 Renthals chain.
Problem is the new chain has about 30mm slack, (tight spot), having set the chain with about 10mm play as recommended , when rotated it has way to much slack.
Anyone else had a similar problem and knows how to cure it.
I changed the front back to the original tonight and same problem, so I've eliminated the front sprocket, I've also clamped a piece of wood to the swinging arm against the rear sprocket and it appears to be true, this leaves the new chain, which I find a little hard to believe is faulty?
Any ideas?

It might be bit hard with the chain in the bike. You could try counting a set number of links e.g. 15 and measure them, count the next 15 and measure them until you reach the start. Ideally divide the totoal number of links into 4 or 5 sections . Measure them when they are not sagging. See if you get different numbers.
 
Not the same length as old chain, due to change in gearing.
Am going to measure the chain links tonight.
 
Lot of "tight spot" to have to stretch to even the chain.

Do you mean the new chain has kinks in it that prevent it from straightening out? If so move the chain adjusters so the chain has 0mm play. Rotate the tire by hand a few times so the chain makes at least 1 complete rotation. Check the play and repeat if necessary.
 
no, no kinks, it is like a old worn chain with tight spots rotate, and 30-40mm slack-tight spots. something is not right, just not sure what.

Perhaps it needs to stretch some. New chains can we weird.

Might be something to this. I experienced the same problem changing the gearing on my 310 (new rear and chain). I set it up on the loose side and rode it for about an hour and after that it adjusted up fine.
 
Mine stretched enough during the first couple hours that I went back and took out another link. I left it a bit long in the first place so I could keep the tire out of the mud flap.
 
Changed the "expensive " rear Superprox, as it wasn't a tight fit on the hub, as it was a 1.5mm ish out,and couldn't centre it giving it an egg shape, had to buy another sprocket to prove this and eliminate the chain as the culprit. Another £30.00 for an alloy Renthals on top of the £70.00 Supersprox, now cured the problem. I didn't know a sprocket would be manufactured, either to big or out of shape, but I suppose its like anything.
Emailed Supersprox and am awaiting a reply.

Thanks for the update, you should try and take some measurements before you give it back to them for them to look at it, they should definitely refund you.
 
supersprox was a brilliant service, but my sprocket was spot on so i guess tolerances or machines have worn.. bad luck bro, where in uk are you moto?
im in gloucestershire trying to sus out howmany husky owners are in uk im up to 3 others now lol
