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 The previous version was outdated and no longer supported.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

All 2st What temperature on engine is right?

Husqvarna
AA Class
My question is what the temperature should be on the 2-stroke engines. How do i know that my engine isn´t too cold for the iceracing for example? How do i measure it?

u can get an infrared heat sensor, or some temperature stickers.

I think it would be fine as soon as its warmed up. AFAIK the thermostat on the bike will cut off coolant flow until the engine reaches operating temperature.

Therefore it really wouldn't ever be too cold.

At least thats how a vehicle engine works, I believe it applies to bikes as well.

On my KTMs yes that would be true,....however I don't think the WR300 has a thermostat. At least my '09 doesn't have one.
 
See if in the package you should have got with the bike there is a sheet of some sort to put in front of one radiator. The ktm I have with a thermostat only does it effect one radiator and you put the sheet in front of the other one in the winter. Just from looking at the size of the radiators and the water pump seems one on a modern bike would be pretty close to the effect of two older ones like late eighties. Actually find the themostat and make sure it is there. I would think something from automotive with a guage on the dash and a sensor to go in the water jacket if there isn't anything specifically motorcycle oriented. How about carb icing?

Johnny's a Swede,...and I'm presuming his bike is the Euro model, so I don't know if they're different or not. But here's the parts fiche breakdown of the US/CAN '09 WR300 like mine,......no thermostat.

I did get the black plastic block off plate,...but you could make one of those out of a Prestone jug or something and zip tie it in place.

You´re right, there is no thermostat on it, but maybe it´s a good idea to put some temperature stickers on then? I have covered half of both radiators now, and it runs fine, but you know, you want to make it as good as possible=)! New bike too, so i want to be careful, but it ran like a jet plane today! Lots of power! Nice iceracing today!

water temperature should be above 45°c.

temperature devices are available from many supplyers. examples:

Ok! Thanks!
i placed the blue piece in the big tube that goes from the radiators to the water pump. this means that the temperature i gave you is the "cold" water temperature.

Ok! Great! Do you know if they sell parts abroad? What did you pay for a complete kit, and which kit was it?
 
rasputin;69170 said:
do you mean the shop of which i posted the links? yes, they sell to sweden.

r

Ok. Is that the one you have? Just so i know if it fits my bike. Is there any part nr or do they know which one fits the WR 300? Do you remeber what you paid?

Thanks again!

i'm using the blue connector piece (16mm, if i remember correctly), in combination with a japanese thermometer device that a colleague gave to me.
kart dealers usually stock these items, cost should be around 50-60 euro (for good quality; you can also spend 100 euro, of course).
