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 The previous version was outdated and no longer supported.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

125-200cc Compression: Rings or Rebuild

Hey Guys,

If the compression reading is below 160, do you assume re-build or is re-ringing an option?

And if you are re-building for the first time, is an oversize bore assumed or can you drop in a stock-sized new piston and call it a day?

Thanks!
 
160 isn't that bad.

You shouldn't have to overbore, unless you have damage to the cylinder wall. Stock piston should work.
 
I was told mine should be 160-165.
At 25 +/- hrs it was 140-145, so I did a ring. After the ring, it was 145-150.
After doing a bunch of searching on here, it seems that my numbers are normal, but the 125 may be a little higher.
 
Look in the manual for your bike, find the wear limit/maximum piston to cyl clearence. Measure it exactly how the manual tells you to. Doing it this way removes the guess work! It would be safe to assume if you have say 25 hours on it, and have used up .002 worth of clearance. You will use another .002 in 25 hours.Don't skip measuring the squish band clearance eaither. The lower portion of the piston is widest, so you will have to slide the feeler guage in far enough to reach
