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 The previous version was outdated and no longer supported.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

TR 650- chainslider / sprocket/ chainwheel not in line??

On my terra the chain and chainslider do not get in contact as they should do. Whether the chain should run a bit more to the right or the chainslider should be mounted more on the left.
Furthermore I removed the sprocket after 700 miles and saw that the sprocket shows nearly no wear on the outer side (right side) on the teeth, but severe wear with blank polished arears on the inner side (left) side near the foot of the teeth. This tells me that sprocket and chainwheel do not run in line.
To check this in detail I removed the screw of the sprocket and rolled the bike in neutral several meters for- and backwards. As a resulte the sprocket slided a bit (2-3mm) off the the shaft.
I showed these findings to my BMW/Husqvarna dealer in Aachen/Germany and after rechecking with terras/stradas in the showroom and a call with Husqvarna. The simple answer was: This is the state of production/technic and he cannot solve the issue.
Fact is that an offset between sprocket and chainwheel will lead to excessive chainwear or excessive wear on the sprocket. Any similar findings on your side?

It's just the way it is. My 03 Suzuki DL1000 had the same issue which could be fixed by changing some of the spacers on the rear wheel. I'm sure a fix is possible. Perhaps some washers behind the counter-shaft sprocket? I intend to examine mine today and get back. Thanks for the heads up on this.
 
It’s not a production line issue as mine is perfect.... Check you rear wheel alignment properly by measuring the distance from the swing arm spindle to the wheel spindle is the same both sides [KTM make a tool for this] The swingarm spindle is the reference point at which all frame measurements start from.. If your wheel is inline and the sprockets are misaligned then your frame is out of alignment.. I had this with a KTM 690 SMC and had the bike replaced under warranty.. It was a long way out though –]
 
I replaced the chain and sprockets at 8354kms. The front was starting to wear as per normal, albeit very early but when I removed it I found it was quite badly worn on the engine side. Approximately 0.4 mm had been ground off the rear face of he counter shaft sprocket. My friend who bought his Terra at the same time had the same problem. The aftermarket rear sprocket had a rebate machined into the outside face to save weight so I reversed the sprocket when I installed it which has effectively moved the chain 1.5 mm towards the centerline. I didn't do the math to see how effective this will be but I will keep an eye on it and see how it goes. Having a case saver makes that so much easier.

BTW I replaced the counter shaft sprocket retaining bolt with a 10.9 strength (vice the 8.8) and lock wired it for good measure.
