solid dependable bike decides to misbehave

[Cognitive_Faux]

evening bcf.


first up. been a long time since i have posted anything here.... like 3 4 years....

4 years ago, i bought my self a honda vfr750, standard.

and has been 100% reliable and dependable ever since.

serviced reguleraly, annually.


however.. today... something occured. so i need advice please.


while on my way out of the office, just started the bike, choke was on. phone call.. took longer than expected... bike ran with choke on for longer than usual. i would say 5 7 minutes. turned choke off... conked out. started again but felt suggish... but temp guage was of the chart. so i left it to cool down...

it ran ok the 4 miles home but again the temp have climbed up.

whats is happening or going to happen...

thank you people.

You probably have fouled the plugs up which is why it stalled when you let it off choke as the revs were to low for it to idle.

The high temp will be from it not moving. Not moving = no air through rad to cool the water. I would have expected the fan to cut in though. If it didn't you still had a fair way to go before it got properly hot EDIT:or its broken

It probably was hotter than your used to as the temp of most bikes sits pretty low this time of year. Around 70 degrees or so. In the summer this will easily shoot up to 100+ so I wouldn't worry to much. Take it for a good run to clean the plugs.

Is it a digital temp gauge or an analogue one?

If it was digital what temp was it reading? Anything below 110 degrees and your safe. Anything above that and there is a serious problem somewhere!! The bike should never get that hot.

I'd second a bike getting too hot can be related to the fan being broken or not switching on. Although yes, they don't like standing still, and it does heat them up more.
Also check your coolant level, as a matter of course.

They do get hot pretty quickly if they're not moving although as said, the fan should have been on if the temperature was in the red so that's one thing, either your fan or fan switch isn't working.

Test by disconnecting the wire from the fan switch (there is only one) and connecting it to earth with the ignition on. The fan should come on. If it does, the switch is not working. If it doesn't, the fan is not working.

Maybe worth giving the radiator a clean off? I did mine recently and its running noticeably cooler. I took the plastic gurard off, gave it a good soaking by spraying it with hot soapy water followed by cold fresh water to loosen any dirt then gave it a blow through with an airline. Blasted a fairly impressive quantity of dead flies and road grit out.

thanks guys.

its an anolouge guage. and its never been accurate just like all the other guages.. epescially the fuel.


now that you mention the fan.. i cant remember it ever working.... unless its really quiet.

clean the rad off? ok.

thanks. hopefully no news is good news

my bike stays clean becuase my car doesnt.



possible the fan has never worked then hahaa

im use to cleaning chunks of mud and chalk and all sorts of crap out of the radiator and mechanical parts of my car/jeep (i go off roading in it alot) and always use to a fan kicking in.

i dont tend to get stuck in traffic when on the bike so havent noticed the fan kicking in... i would imagen the fan would run even if the engine didnt. (ignition on) which means then.. if thats true.. it doesnt work.



right then coolent oil levels things like that i will check.

not bad considering the bike has done 24k since 1995
