Water cooling the Bucket

[TZ350]

I know its not Buckets but it is thermosyphon and cooling by latent heat of evaporation.

I remember the thermosyphon water cooled single cylinder engines that ran milking machines, water pumps and shearing sheds on remoter farms. Usually the radiator was just a 44 gal drum fill of water sitting on a stand next to the motor. As the water evaporated away, it was topped up.

Some engines used a different principal and relied on the latent heat of evaporation to directly cool the cylinder and had a water reservoir cast above the cylinder, which was kept topped up.

Two engines with water drums can be seen on the back of the trailer and one with a cast reservoir can be seen at the front right corner of the trailer.

So I fitted a temp gauge to the bike, got a slight problem though, it's obviously getting interference from the ignition because as soon as the bike is turning over, the display goes blank doh! but once the motor has stopped, it shows the temp. I took the bike for a quick test run after warming it up and I may have hit the jack pot as the temp seemed to stabalise at around 50 degrees, which is a little to cool, I will aim for 55 but better to run cold than run hot!

Can't wait to really put it to the test!

Wicked! How do you make it run a little hotter with a system like that? So you will make an appearance at the next buckets then?

As dave said, you could tape up part of the radiator to reduce the amount of cooling fins exposed.

Pretty cool dude, did it pretty frecken quick too!

That was Mike, but yeah common to tape. Was it a Daytona temp gauge? I had no end of problems with mine getting interference. I was going to run a thin coax wire & maybe some filtering but lost interest.

Perhaps reducing the diamater of the piping from the radiator to the head and back, could also reduce the amount of fluid being able to be flowed.

Anywho, doesn't seem too far off. A fair bit of hard riding should bring it up a couple of more degress.

get a rg50 temp gfauge they were accurate as always at half on the gauge

I have had the same problem with all the daytona stuff, (incl ex temp sensors, and rev counters), I wrapped the pick up lead on one with tin foil, then covered it in insulation tape, and it worked, dod the same for another and it made no difference.

Go figure.

[F5 Dave]

yeah a friend had the same gauge mounted on the same type of bike in the same place with the same ignition & the same plugcap & had no problem. I had one 2nd hand one, a new one & a replacement one give trouble. Maybe it knew he worked for the distributor at the time so gave no issue.

The Daytona gauges tend to have fairly flimsy wiring into the back of the unit, we always used to replace and resolder it when we ran them in the Karts
