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 The previous version was outdated and no longer supported.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

Zip Ty Racing waterless coolant

I dont know but the only one I can think of. Once you use it you will be like, humm.... thats pretty cool. :)

I was actually pist the first time I used it, wondering wtf no one had told me earlier. I lost three RFS racing engines due to over boiling in the desert, all of which could have been avoided with $23 bucks worth of XF. I'd say it's pretty damn cheap considering it lasts the life of the bike. The down side? If you have an emergency and have to put water in it, you can, and it still keeps pretty sweet 257° boiling protection. But when you get home, you have to drain it all out and put fresh XF in again. :cool:

Thanks Tinken. It has to be your coolant because before the fan would turn on in about 5 minutes.

Please let us know how the XF works in your TR650 in the long term, maybe after a couple of rides. And thank you for using our product!
 
For Aussie consumers, I noticed Autobarn has started selling Evans Power Cool 180. Not sure about the quantity options tho.
Liquid Intelligence 115 has a 1.5lt tin which is rite for the TR.
 
Question - If I replace my coolant with XF and fill the system and radiator, what is the optimum level and do I still need the Expansion tank to be connected or will it become redundant?

The safe answer is... keep the tank and keep the coolant to the same level.
The reason I've retained my tank is because I dont want any air in the system.
XF2 and 115 are made for motorcycles. If you go to the evans be sure to get the motorcycle blend.
Hope this helps:D
 
Here this man says two interesting things:
1-«Evans has been designed in a way that the additives stay suspended within the solution at all times, so we hear many comments, especially from people who don't drive their car every day, that when they do get to drive it, they have to replace their coolant and that's because the additives drop out, they settle at the bottom of the cooling system, they crystallize and that coolant is, effectively, useless.».
The last time in which I flushed my (water based) coolant, I noticed that at the bottom of the bottle into which I poured it there were some white solid things!
I've kept it for inspection purposes and today I've taken a photo:

2-«We get comments that water is the best thermal conductor and it's true, we can't argue with that, but only in its liquid state, so, once the water becomes vapuor, the thermo-conductivity of water is no longer relevant. That vapour, within the cooling system, actually creates pockets throughout the cooling jackets and separates the coolant from the metal components, stopping any heat transfer.» (Like Tinken already wrote in the previous page).

That is my thinking also. I made sure there was some XF2 in the overflow tank so when it cooled back down it didn't suck any air into the system. I filled mine to pretty much overflowing with the engine hot and running, then slapped the cap on quick.
 
That white precipitate is just DKP. It doesn't dissolve in EG well, so manufactures like Evans must add a little bit of water. XF2 contains no DKP and only trace amounts of water because it is hydroscopic (pulls water out of the air), far less than Evans. As tested, Evans turns dark brown when heated, XF2 did not. We use very high grade EG which contains less contaminates such as water.
