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 The previous version was outdated and no longer supported.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

Another one Bites the Dust

I also have two riders so far, confirm that the new XF2 coolant flows perfectly past the oem thermostat, no flow issues, no overheating.
 
Sorry, I had an issue with one of my coolant labels and I had to hold shipments. I will get everyone's coolant out in a couple of days.

I received my XF2 coolant yesterday, wahoo!

Thanks Tinken.

Easy Peasy Dan. remove right side plastic, remove bottom screw on water pump, put a large diameter drain pan underneath, then remove the radiator cap. GUSH. let drain overnight. Blow out with compressed air. pour into radiator slowly to let the air escape. Do this at least 3 times and top off the coolant bottle. Then RIDE ON!!

I did the XF2 coolant swap today.

Something I'd add to the process is I found a fair amount of coolant remains in the radiator as there's no low level drain for it.

I removed the lower hose and leaned the bike over to the right as far as practical and about a pint more coolant came out of the radiator.



Another thing I'd add, I made sure the overflow tank drained out into the radiator neck. Then I pinched off the overflow tube with a pair of forceps. I then added new coolant to the overflow tank and released the forceps and allowed some to drain out until it ran smooth, then pinched it back off. I then proceeded with the slow fill of new coolant burping and allowing air to escape as I did so.

I started the bike and let it warm up adding coolant as needed to keep the level to the top. I could see the thermostat open and coolant start to circulate, then topped off again. after the fans had turned on and cycled on/off a couple times I did my final top off and put the radiator cap on and released the forceps on the overflow tube. Then I let it cool back down.

I'd say it has much more thermal inertia now, it takes much longer for the temps to rise and overall it's more steady. It will rise to where the fans kick on but they will lower the temp bar back down. How far depends on how heat soaked the engine is, either to where they kicked on and hold, or further down and then stop.

One thing I noticed is now I will see the temp drop even when riding very slow in 1st gear, say 10-11 mph and hold at a lower temperature. I think a combo of the holes in the fender, no air pockets, and a high quality coolant makes the improvement.

I'd say the cooling system mods are done and it's working to my expectations.

The thermostat block off devices went on the milling machines today. Should see working units by next Monday. I will probably need a test guinea pig.

I would be very interested in being your guinea pig. I've been waiting for you to announce this.
 
Wow that's a better offer than those new drug trials. The only side effect is getting to try a little Tinken magic and smiling.
