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 The previous version was outdated and no longer supported.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

Solving TE570 Vibration, counterbalancer?

I've been converting my TE570 to a street bike (SM 17's, dropped 9 teeth out back, etc) and took it on a long trip for the first time this past week. With the 40t sprocket the RPM's are at a comfortable range at 65mph, however the vibration is NOT. I had to keep shifting my weight between punishing my feet or ass. It's like riding a giant palm sander.

I'm wondering if any of the SM models have a counterbalancer that can be swapped into the TE570? I'm hoping I don't have to fabricate rubber motor mounts to resolve this... Anyone have any fixes?
 
No way to install a counterbalance shaft, different engine designs. I'm sorry, but the 570 was never supposed to be ridden at 65 mph for any length of time, and the engine isn't happy to do that either. I guess you could try with rubber engine mounts, but I don't know how much that could help.

It may help to get the engine internals ( crank, rod @ piston ) balanced by a professional company who has a dynamic balancer. Has someone changed out the piston in your engine at some stage?
I know the left kick engines were renowned for their vibration. `

I have no idea if the piston has been swapped out. I'm going to be opening it up to do the rings and valve seals at least so if I can solve this internally now's the time.

How would they balance it? Don't you need a weight to counter the punch of the piston to do that? I have no experience in this realm...
