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 The previous version was outdated and no longer supported.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

Anyone else having a hard time adjusting their TC250 chain?

I have never had such a difficult time getting the chain adjusted on a bike. I have to get it really loose when on the stand, so it is not tight when the suspension is compressed. Too tight...and the countershaft sprocket seal begins to weep. To loose and the chain is rattling around, and my family is wondering what is going on with my bike.

None with my son's other than it needs adjusting after every ride it seems. I think we'll go with a beter chain soon. LOL it is loud now that you mention it. I allways tell him "hey you need to tighten up that chain!" as he clanks around me on the MX track.

Maybe that is it, just need a better chain.

The swingarm pivot doesn't seem any farther from the counter sprocket than other bikes but I have to leave my chain pretty loose too.
 
I noticed the same thing.

The quality of the chain has nothing to do with it. It's the suspension/chain geometry.

It needs a lot of slack on the stand...like a KTM.
 
Are you guys setting the chain at the 35mm slack @ 145mm from the pivot like suggested and still finding it too tight?
 
I don't find my sons chain to tight, we set it up ride it a few hours then it needs to be re-set. It just seams to need adjusting more often than most.
 
I always pull out the swingarm linkage bolt out. That way you get free full travel and its way easier to set the chain tension right. Once you find the tightest spot in the travel, set it there.

measuring the slack with the shock in place is not precise enough IMO.

It's surprisingly loose on the tc250...
 
I do all my bikes the same.

1) Put the bike on a stand with the rear wheel off the ground, put a tiedown strap through the rear wheel and over the seat.

2) Crank the tiedown until the counter sprocket, swing arm pivot and rear axle are all in alignment. This is the point where the two sprockets will be the farthest apart.

3) Adjust the chain for a little slack, I make mine so I can move my chain up and down about 1/2" with my fingers.

4) Tighten up the rear axle, take off the tiedown and let the rear wheel hang down all the way on the stand.

5) Measure and record the slack in the chain at a certain point. On my Husky I measure from the top of the rear bolt of the slider to the bottom of the chain as I am lifting up the chain with my fingers. I write the measurement right on the swing arm with permanent marker. After the first time I just use my recorded measurement to adjust the chain.

I do our TC per Husky instructions and find that it will loosen a bit after a few races. I'm like most here and think a higher quality chain would be the ticket.
