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 The previous version was outdated and no longer supported.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

Certainly some mixed feelings out there with many focusing on the possible lack of negative impacts. Well I have not had any, and I have had only positive results imho. As previously stated at 100:1 mix ratio the bike is running as per expectations. It is not smoking, there is no spooge eminating from the exhaust, the motor is not running rich or lean. It is however imho running smoother, the bike (both my bikes) seem to be the better for it. I am convinced it is a positive thing to do. Just think of it as cheap valve and piston maintenance that results in enging longevity. Not to mention the aid to fuel left in the tank. If a racing team uses this approach with success and personal use for over 2 years has only produced good outcomes, ie not one mechanical failure then where's the negatives?
 
I just bought lucas upper cyl. lube. I think i will give it a try. I don't think it could hurt to give the fuel pump,fuel injector and upper cylinder a little extra lube.
 
I squirt in a shot of 2T oil and run the bike a bit before storage in the winter....just to coat the upper cylinder...and I think it helps the accel pump and seal from drying out....I run it out in the spring

but I am not sure for those with a cat converter and O2 sensor.....probably risky??

nope, I spent a lot of time researching this, and people seem to say it, because they heard it, or assume it. However, they are never able to back it up with facts. All the facts I found showed it does not hurt o2 sensor or cats, unless you run very high ratios and the exhaust temp is increased enough to damage the cats, nothing like what we are talking about

I see klotz makes uplon fuel lube just for 4st. Thay say to run it at 256:1 ratio. Any one use it.

I run Klotz in every engine on our dyno here at work, good stuff.
 
I decided to try it on my 05 tc 450. These bikes run hot. I race Hare Scrambles on the East Coast and Run Evans coolant. I ran Honda HP2 at 175 to 1 and noticed cooler operating temps. Don't see the down side of doing it.
