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 The previous version was outdated and no longer supported.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

250-500cc Pic of my WR250 Piston

Wiseco's do heat up and expand somewhat unevenly, but in stock engines, they do just fine. In heavily ported or very large bores, like 500cc, I like to add another .5 to 1 thousandths clearance (in any boreable barrel) to make sure the piston will not stick on break-in. other than that, Wiseco pistons hold up really well for a long time. I use them in all my bikes.

The ProX piston that I won on ebay is out of stock (it makes me so happy to find that out after waiting a couple weeks), so I went with another Wiseco. Hopefully now that the bike is mikuniless, this next Wiseco will have an easier life.

I saw those ProX pistons for the first time the other day. Are they an "Asian" product?

I was just over talking to Ron at RB designs yesterday. We started taliking about pistons and he believes Wisecos aren't finished quite as good as the once were. He feels they don't do as much pickiling/stress relieving, so the first few quick heat cycles are more important than ever.

Thanks for the info. I will take my time doing the heat cycles.
 
The pro-x piston I bought was ugly and I did not want to put it in an engine of mine. I would rather use the wiseco piston.
