I was just going to put in new rings for the 100 hour service but after i got it apart it seamed like short money for a piston as well as new rings, even though the original piston looked great. Is it the A piston or the B piston. Slavens says B piston for any 300 over 25 hours. I have just over 100 hours and like 2000 miles.

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 The previous version was outdated and no longer supported.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!

I have 88 hours and are installing a B piston and rings tonight...will let you know how it makes out. I know people say it can go 150 or even 200 hours, but I do it once a year regardless, it is cheap and keeps things in top shape. I race also, so maybe 150 hours at trail pace is OK.

Measure the bore with a dial bore gauge that is accurate to .0001" and there won't be any reason to guess if an A or B is correct. I had an Italian WR250 that had well over 200 hours and was able to go back to the same exact size piston as the original. The difference between the A, B, C, and so on is only a 1-3 ten thousands of an inch per each letter size which means even if you guess wrong it is not likely to cause a problem unless you disregard the break in procedure.
