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 The previous version was outdated and no longer supported.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!

Don't do this.
Find a ratio you are going to always use, jet the bike for this ratio and ride the bike. Adding more oil makes a leaner air fuel ratio and we all know what happens when you lean thing out to much.
True. I brought home my new 300 last spring, and as soon as I made sure that it had the correct jetting in it, I mixed the Motorex at 60 to 1 and have been running that ever since.

As far as the premix goes, i started with the break in mix for like 2 tankfuls and then went to 42:1. May seem a little thick but it runs awesome, never stalls, and Ive only changed the plug once in 20 hours just cuz Im a stickler for maintenance. There was nothing wrong with it.

in reality adding oil means less gas going through the carb jets, but in the real world unless you are leaned out as far as you dare you will find 32:1 vs 40:1 not as dramatic as it looks and that is a big change
now that sid I always reccomend rejetting after any fuel or ratio change
as to 32:1 is 3% added oil as in not fuel and 40:1 is 2.5% added oil, 32 parts fuel to 1 part of oil,
over the years I have changed oils I remember when 16:1 was the common mix, I went to 32:1 in the 70's, 40:1 in the 90's I am currently running 50:1 and I did rejet as necessary

Sure what ever you say. I have only being repair mistakes like this for 30 years or so but I'm sure you're correct. Thanks
Yep, I agree. Manual says so and there is no issues doing that. Going from 40:1 to 30:1 with good oil will make no difference and you have to go way off the map to make it so gas lean it would be a problem and you would have so much oil it would be near impossible to seize it. Run a few 32:1's through it and then find out what you want to run and do that. I like Amsoil at 40:1 and feel it is super reliable doing so. Have tested this big time a few times.
More oil means leaner mixture because there is less fuel per volume. The more oil displaces fuel per unit and makes it leaner (air to fuel mixture). Make sense? IMHO though not enough to matter.
No reason to have an attitude about it, this is a wide spread misconception and understandable. Would have taken the same effort to explain as it did to be sarcastic.
