thermostat, remove or not?

Ramo1 · Apr 27, 2006

Do you guys have an opinion one way or the other about removing the thermostat and related hoses, and just using an inlet and outlet hose? This is the first bike I've had with a thermostat, and it just seems there could be too many places for leaks or punctured hoses. I get the idea, but is it really necessary to run it?

They are trouble-free. I'd leave it stock.

That is a good question, I don't know the answer but like you suspect you should remove it if you live in Cal, or Aust. It is for cold weather, when it is hot which would be the Aust and parts of US situation it may cause problems. I think I would remove it, but am always really cautious of messing with what experienced engineers have set up. The main acception in the paste has been the breather hose.

FE600,
I tend to agree with you about the removal. Does the system help with keeping the jetting more consistant? I will usually ride in temps between 45-100 not usually any colder. With summer on the way I guess I would like to stay as cool as possible. I'm still stumped, but thanks for the input.

I would say to leave it in.
The thermostat is designed with one thing in mind, to maintain a stable temp in an engine. It does this in one way that works differently in summer and winter.
It is designed to slow the flow of water to allow it to heat up in the engine, winter time, or cool down in the radiator, summer.
If you remove it it will not cool down in the summer it will actually overheat the water and boil the engine. In the winter it will not heat up and the bike will not run properley.

If your engine is overheating you should try some additives in the radiator, like a good quality coolant like ice. Dont just use water, it boils at 100c and just isnt good enough. A good coolant will rasie it above 125c.

I heartily agree with squizz, the thermostat will enhance the engine life by providing a more constant temperature, and quicker warm ups. A poor design could cause overheating, but the Berg's seems to work fine! Buzzard

Thanks guys, I knew I would get good info on the issue. Went out for a 60 miler, and for the first time had some boilover problems although it was slow going at times I suspect air flow was the problem. I think I will leave the bike as is, and try some addditives as squizz suggested. I'll let you know if all goes well.

Thanks again,

Ramo

Hi Ramo,
I suggest leaving the thermostat installed, changing to a water-less coolant and installing a temperature gauge.

Hope this helps.
