Overheating in idle???

Its a 929rr 2001 and has only 853 miles on it. Only had it a week and had to replace the 30 fuse and charge battery to get it started. Thats all and hadn't been cranked in two years or more. Thats Honda at its best. I have new oil and filter in the bike and the coolant level reads fine but today I started the bike and leave it running in idle for awhile as the temp just kept climbing so when it got to the danger zone I shut it off and let it cool. What temp should I be at 165 to 180 or what and what else should I look for to cause this problem besides coolant level? Please help I don't want to damage the bike but I also cant afford to go to Honda right now either, thanks.

Re: Overheating in idle???

Did you replace the coolant? Who knows what mixture is in there and how long it's sat. Don't know what the temp reading should be but that would be the first thing I would do. Then check the thermostat to make sure it's not sticking. My 954 runs around 180ish in the cooler weather and the fan kicks on at 217. Don't know if that helps.

The only thing I trust on the road are the nine hundred and fifty four CC under me..........

How on earth does an eight year old Jap bike (very common on Italian junk)have less than 1000 miles on it?
Normal temp is around 85-ish Celcius and the fan comes on just above 100C. I don't work in F but I don't think 180 is up to normal temp yet?
What did you consider to be the "danger zone" exactly?

Re: Overheating in idle???

yeah that helps for sure I would say the 929 should be close to yours at 180. I did notice the fan never cut on I checked all fuses before I'll look again at that. What kinda coolant you recommend and how do i check the thermo?

thanks for reply

In that case, the bike is not overheating at all.

Then the fan should have been on long before then.
Check the fan and the fan switch in the radiator.
Without the fan the bike _will_ overheat while idling.

Re: Overheating in idle???

Lots of threads on coolants. I'm going to try engine ice or wet wetter next. Take the thermostat out and put in a pot of water with a thermometer. Heat the water and look at what temp the thermostat opens. I don't know when it should open though. Bladeracer could probably help you out with that.

Sorry, I overlooked that fact that the fan wasn't running............yeah, check that first.

Amazing but also sad to leave a thoroughbred sitting like that all these years.

Since I appear to have been nominated ;-)

Thermo opens at 80.5 to 83.5C and is fully open 8mm by 95C.
Fan switch comes on at 98-102C and off at 93-97C.
Despite my Haynes being printed in the USA it doesn't bother with fahrenheit - and rightly so.

Practise and use higher gears.
Have you ridden before?
