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 The previous version was outdated and no longer supported.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

Rich and lean refers to any combination of items, whether it's gas and oil, air and fuel, or whatever else you happen to be talking about

Exactly right. We happened to be talking about the net mixture ratio entering the combustion chamber, which is fuel and air. Oil displaces fuel in that mixture ratio.
 
This is ancient history but when Belray MC-1 came out in 1979 the recommended mix ratio on the bottle was 85:1. I ran a whole season of MX at 85:1 on an aircooled 400 maico. Ran like a champ, no issue and 53 races on the same top end. I did need a piston at the end on the season, but the oil worked superbly. The new bottles say 50:1. I asked Belray about this and they told me that is was for public perception and most people were scared of running lean oil ratios. I now run the MC-1 at a sedate 60:1, but my old KX500 got 400 hrs summer single tracking and winter ice racing. Lots of great oils out there to use. I just wish the MC1 smelled like the Maxima 927. I tried the H1-R but somehow the bike didnt seem to run as well and gave more spooge. I think the main thing is to find a good oil that you like and stick with it. I am testing amsoil marine in my outboard this year. Cam.
 
You can get away with lean mix ratios with big bikes like that because you don't scream them like 125's. I did the same thing in the 70's with Belray and went through bottom ends on my 100's and 125's

Nice! I got Maico support in '81 &'82. I was in Boise and the bikes came from a shop in Kali. A leftover '78, then a leftover '79, MC250s. Both came with a case of MC1 and a Mik carb. We did break in at 32:1 and raced at 50:1. Don't remember what it said on the bottle :rolleyes:
:cheers:
