• 4 Stroke Husqvarna Motorcycles Made In Italy - About 1989 to 2014
     TE = 4st Enduro & TC = 4st Cross

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 The previous version was outdated and no longer supported.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

Need TE511 Chain/Sprockets Recommendation

OK, thanks for the response. I thought you were talking about the difference between my BMW's 5th gear ratio and the TE's 6th gear ratio. No wonder I couldn't figure out what you were talking about. They are pretty close to one another the BMW being taller a bit but certainly not 33%. You and myself seem to be the only ones whom appreciate the BMW gear box as well. I remember it shifting silky smooth all the time even when beat hard with out the clutch. Don't get me wrong the TC shifts faultlessly too and I seldom use the clutch once under way. A bad habit from my old Maico riding days.

I'll be sticking the BMW back in after I have you frehen it up, Big Bore,head chamber and port work. My forum buddy Matt, whom I sent to see you, has been out with the BMW G450X you just completed and says it has way more power than he needs. He'll be a full on dirt rider soon and is enjoying the bike immensely. Still farkling though.

I understand the sprocket logic and am always concerned with front countershaft bearing wear. I've seen it wear out and chew up the swingarm pivot shafts a few times on the BMWs. I haven't seen anything larger than a 51 for the rear for the BMW. Its the same sprocket as the v-twin Aprilia 450/550 Enduro's. If I went to a 15/51 or larger in the rear if available. I think the wheel would be so far forward it would chew up the rear chain guide. Nobody that I am aware of sells a quality aftermarket chainguide so I would have to pick up a good used one off ebay to have for spare parts for around 30.00. A new one is probably 3 times that, which is typical.

... but 14/52 seemed pretty balanced, while still providing stump pulling power in 1st. Top speed with this ratio is about 83mph and cruises around 55.

I run the stock, which I believe is 15/51. I thought you told me that 55 is too much for cruising but with lower gearing you say 55 is ok? Maybe that was because of my little oil barfing situation? I now run the full oil recirc kit so I'm going to try 55 for a short run and see how it does. RPMs seem pretty low to me at that speed, and I'm thinking of going to a 14 front too.

I use all DirtTricks Ironman sprockets. They are stronger and last longer than even SuperSprox. I didn't have to replace my Ironman sprocket on my KTM race bike until after 6000 race miles.

I second this, super long wearing sprockets.

Probably should change the front. You don't have to but it will be much nicer to your new chain if you do.

As for chains the $50 SRT chain is very nice and holding up well for me so far. Several KTM buddies running them.

Will I have to cut it if I go with 14/52? I've never cut a chain.

Not sure but cutting a chain is EZ. Grind the pins down on one side and use a screw driver to pry the link side plate off.

Get your new sprockets on first. Then adjust your adjusters all the way in so you can move your wheel as far forward as makes sense. Than lay your cain on and mark the side plate that needs to come off. You need to end up with two inside links as the Master is the outside link.

Here - just found you a complete how too...

but the stress you are putting on your chain, sprocket and CS bearing going from a 15 down to a 13 is far greater. I played around with a 13/51 and it was too low in first, but 14/52 seemed pretty balanced, while still providing stump pulling power in 1st.

Huh, I was unaware of this. I'm running a 13/51 for tight east coast single track and like it but didn't realize that I could be stressing the drive train.
 
Has to do with the angle of the chain off of the guide to the cs sprocket. It does put added pressure on the output bearing side. Though it may cost more to purchase a 53 or 54 rear sprocket, it may be cheaper in the long term not having to replace the output bearing and seal.
