Hi all, First post on here so here we go.. I just bought my VTR and notice the the temp on the digital display is at 97 98 degrees C (Australia).. My question is what is normal temp for the bikes to run at? I just get the feeling that 97 is too much.. Any replies will help greatly. Cheers, Tony

 

welcome Tony. glad to have a new member. I wouldn't worry about that temp. I would change the antifreeze and all fluids if you don't have proof of recent changes. It's cheap insurance and gets you acquainted with the basics.

 

Welcome aboard. 97-98C (206-208F) should be fine. A quick search online said the stock fan does not kick in until 102C/216F.

 

A lot depends on road speed and ambient temperature. If you're travelling at 50 kph in 30 degree celsius weather for any length of time your temp gauge will be registering in the 90's. As long as the fan kicks in as captainchaos said and the coolant is at the proper level, you're OK. Enjoy the ride. Welcome to the forum.

 

Welcome to the forum.

And those temps are fine.

 

Welcome to the site...

 

Thank you to all for the information and for the welcome.... I was under the simple of idea if water boils at 100 deg c then 97 to 98 is way to hot but if this is the norm then i am cool with it Thank you to all for the speedy replies and the warm welcome. I have been scanning this forum for weeks and just joined so im sure i will hear from you all again.. Thank you, Tony

 

Pure water boils at 100c when at sea level and normal air pressure.

The cooling system of any vehicle is pressurized and not pure water. With a 14psi radiator cap pure water will boil at ~127c (260F) and not 100c, add to that "antifreeze" and your coolant will not boil till an even higher temperature than that.

 

Yeah what he said You beat me to it.

 

One of the worst things you can do to a vehicle is run with no radiator cap or a big leak in the cooling system.. As this brings the pressure in the system back down to that of the air around it and allows your coolant to boil much sooner, severely compromising it's ability to cool your engine.

 

I think i will flush the coolant and start fresh.. Thanks for the info all!

 

Use distilled water and silicate-free antifreeze.

 

Use a mix of vinegar and distilled water when flushing the coolant. The acidic vinegar will break down the basic deposits that form because of the coolant.
Basically, drain the old coolant out as well as you can, seal the system up and fill it will water and vinegar. Run the bike till warm, then drain the vinegar mix.
After you do this you can go ahead and fill it up with coolant and distilled water.
Make sure to bleed the system as well.

 

Sweet trick, Ill give it a go in the next week.. Thanks for all the replies and i will post pics up in the next few weeks.. Thanks again

 

another trick. After you drain the vinegar and distilled water , you can let it cool a bit, and then make a great big salad with it.

 

Or add baking soda and watch it bubble and foam.
