My Yamaha YZ80 is spitting coolant back out the radiator and the overflow line

Have you noticed any change in how your temperature gauge is reacting/performing? Is it slow to reach optimal temp? Reach it too fst and then exceed?
If either of the above, suspect stuck thermostat. An inexpensive fix, and a DIY job.

Hi, Anonymous and the usual suspects are:
1. Low coolant level.
2. Restricted radiator air flow.
3. Faulty thermostat.
4. Coolant pump or fans inoperative.
5. Vent hose crimped.
6. Air in the coolant and needs bleeding.
7. Engine idling too long or bike moving too slow.
8. Coolant too old needs to be replaced.

In town my engine temp reach to 108 degree of centigrade.if this temp is harmful for engine,please help me.thankyou

Petrol engines like to run at or just below boiling point. The radiator is pressurised and that stops the coolant from boiling. I would not be happy if it got any hotter as I would worry that the coolant may expand too much and leak.
Try using less power on hot days when in traffic and keep moving the air through the radiator.
Hope this helps.

I have an overheating problem on my 1980 kz 1300 i think its the thermostat but i dont wanna buy a new one if that is not the issue is there any other solutions to this problem or is it the thermostat?

The thermostat will only cause overheating if is not opening - or not opening at the correct temperature. Before replacing it, you may want to rule out some of the other possible causes of overheating: Bent or otherwise obstructed radiator cooling fins, contaminated or insufficient coolant, clogged radiator, incorrect temp gauge reading, inoperative cooling fan, defective radiator cap, etc.
Check the above things, then ask yourself: Does it overheat when riding at highway speeds, or just in slow riding conditions? Is it really overheating? Coolant temps that exceed about 250F is cause for concern. Coolant temperatures which do not exceed 250F while negotiating stop-and-go traffic on a hot summer day are quite acceptable.
If all else appears in good working order, remove the thermostat and place it in a pot of water, over the stove. With a thermometer handy to measure the water temperature, begin heating. You should be able to see the thermostat begin to open by the time the water gets up to 185F - and it should be fully open at 210F. If it fails this basic test, replace it.

2005 Yamaha YZ 250f. suggestions on type of motor oil.

The manual gives different grade for different temp . sorry if your in america these temps are in centigrade.
if it gets below 0 deg C use the thinner oil 10W30
5deg-40deg 15 or 20W40
If it gets to 50degC 20W50
just make sure it is motorcycle oil without friction modifiers or the clutch will slip

I have a 600tt.The temp gets hot very quickly after a 20 min ride, reaching 100 degrees. is this normal

well depends if your ragging the **** out of it if not then check to see if you have coolant and normally when the temp hits 90+c it will drop then get hot again it drops because the thermostate has opened if this is not happening you need to take the thermostate out and dunk it in a cup off boiling water and look at it and you should see it move if not then that needs replacing buddy

My cbr 929 honda is overheating how do i fix this problem

Check the coolant circuit that does not have air at all kept inside.
With the bike cold and the radiator cap open on the bike's kick stand start pressing again and again the coolant pipes and fill in coolant if you have to.Then start the bike without closing the radiator cap and keep pressing-releasing (like a sponge) the pipes until the radiator's lower pipe start getting hot.Then close the cap and wait with the engine running until you hear the radiator fan turn on.If you reach 227 F (108 C)and it hasn't start turn it off and check the temp switch on the radiator or the fan.
If the radiator's lower pipe never get's hot but the temp gauge shows you the temp reaching above 194 F (90 C) then you have a thermostat problem and you should check your cylinder head gasket too for compression failure.
