Question about 2005 Honda Xr 250 Tornado

1 Answer

Overheating I'm having problems with a used Tornado that I recently purchased. After running it for a short time/distance, the engine gets extremely hot and the mechanic suspects, due to other problems it had, that it was overheated at some point in the past. Any ideas why it's overheating?

Surprised that your mechanic didn't mention the spark plug. The wrong plug type is a major cause of overheating. Speak nicely to your local Honda dealer and ask his advice. You don't have to buy your plugs from him once you know which one you need visit your local motor factors the difference in cost will shock you.

SOURCE: Overheating

I've never been a big fan of automotive oil in a bike. That being said, maybe the Castrol can be used in bikes too I don't know. Anyhow, hopefully someone will be along that can better answer that part of your question. There have been many discussions pertaining to what oil to use. Drop a PM to OilDoc. He can probably answer that question very quickly for you. If this was a car, I'd say that the thermostat was stuck. Maybe start there.

SOURCE: overheating

 chances are that your water pump could be bad or thermostat could be stuck closed  if you can locate the thermostat housing warm the motor up and see if the hose's on both sides of the thermostat housing are warm  if it is  it most likely the water pump  and  youll want to keep a 70/30 mixture of water and antifreeze  it the radiator  when filling their should be a air bleed screw some where on the cooling system to bleed any air out of cooling system while your filling it

SOURCE: Overheating

I havn't a clue what you are taking about. The cb400ss ( mine, anyway ) is air cooled, it does not have a radiator,and certainly no temperatur e guage or temp warning light. How do you know it is overheating, and at what temp. it is running at ?

SOURCE: I have an 86 Honda shadow 500 that runs near overheating

A lot of shadows run high on the gauge. I would be concerned if the fan never turned on when in the red /or if the fan ran constantly. You may just have a gauge that reads really high. I ride a Goldwing and totally ignore my gas gauge(it reads empty for half a tank)and my temp gauge many times does not come on at all. My fan does work, but it never kicks in, therefore i am not overheating. Both items are annoying but not worth fixing since they only back up other systems and are mostly there for looks. There are some antifreeze modifiers like "ICE" that are used in racing where antifreeze is not allowed. One of these may help lower a potentially high temperature. But may not be necessary.

I'm running hot about a mile N half down the road how do I no if it's a blown head

A bad head/head gasket will make the radiator hoses extremely pressurized in a short time. If you are driving this distance with a cold engine and the hoses are pressurized, possible head gasket.

Can I tow a 2005 ford expedition 4x4 behind my motorhome without any modifications?

It is not recomended to flat tow your expedition with the engine off and driveshaft in. The oiling system in your transmission runs off of the engine. You can tow short distances but the transmission components will be turning without fresh fluid being moved through them. This will cause exessive wear due to the fluid overheating and losing its ability to lubricate properly. You can flat tow unlimited distances with the engine ideling or the driveshaft removed. if you chose to tow with the engine running you should stop often to make sure you are not overheating the engine. You may not get enough air flow to the radiator while the expedition is behind your motor home.

Which engine?
Are you looking for a leak or does the engine just get hot?
It's been my experience that unless you have the timing too advanced (not probable on computerized engines), or there is a spun bearing (which would make noise), then an overheating problem is most likely (after the thermostat) the radiator being plugged up. It could have been partially defective to start with (no, 'flushing' doesn't usually help).
Bars leak will only make the problem worse.
