Pirate Cycles sells an upgraded Chinese chain...I've never had a problem with them.
HD 415 Chain Nice Quality!!
Yes...and as Justin says in the text...It's the chain that should have come in the kits.
Gonna order one up. Thanks.
You're welcome...and thank you for buying my parts.
Even with the MM sprocket adapter I still get a lot more chain difference from tight to slack than you're getting on my DAX Titan and I've tried 3 chains, one of them a Tsubaki 415. Im sure it's the drive sprocket which I've used 2 of too, one of them far worse than the one on the bike now.
Did you find a decent fix?
No. My chain goes from 1/2" or so to about 2" from tight to loose, it was double that or worse before the MM sprocket adapter. DAX uses counter sprockets made just for their kit as far as I know so I don't know what can be done. I get so much chain/sprocket grinding on the DAX kit I just can't stand to ride it. I never could figure out if the grind comes from the engine to jackshaft chain or the jackshaft to wheel chain or both.
After months of trying I gave up on the DAX and bought a Staton. The Titan kit is gathering dust in my garage.
Do you have the rear rack mount set-up, or the in-frame?
It's the rack mount. Looking on the website it looks like they don't even sell them anymore. If they all ride like the one I have I'm not surprised they dropped them. The kit uses 3 of their counter type sprockets, one on the engine and 2 on the jackshaft. I don't know which one is the problem or if it's all of them. I'm sure it's at least one of them. I have one I took of the jackshaft that the teeth are so far off from centered I can see just looking at it that the low part of the sprocket where the chain actually rides is higher on one side and lower on the other. You should see what it looks like spinning on the jackshaft, up/down, up/down.
Maybe the shaft on the DAX kit is bent??? Jims sprockets are 'dead on'!
It's not the jackshaft and it's not the sprocket adapter/sprocket. The grinding got considerably better with Jim's product but it's still too bad to ride as far as I'm concerened. It feels like it could lock up at any time. Those DAX counter sprockets look pretty cheap, I'm sure they are the problem.
I hope this new chain helps. I made sure again that the sproket was aligned perfect, tightened evenly, and runs true.
that is the difference between American made quality(Jim's),,,
and chinese made not-so-much(dax's)
'nuff said !!!
Hopefully you'll have better luck with that than I did. That Tsubaki 415 chain wasn't cheap.
