My Transalp 700 is running hot, any ideas why?

I think some ally wheel cleaner is acid based like brick cleaner. But do not use on carbon disc braked cars, it disolves the discs.

Well done Mr. Newt. That citric acid is though enough. Use it carefully and in the most secret place. That or Mrs. Newt will give you plenty weekends of unclogging house's pipelines.

So after I have seen that my cooling fan which is attached to my right radiator is much more efficient at cooling down the water temperature from 103 to 98°C, but still having problems on the open roads, decided to attack the left radiator. Got both out yesterday, the right radiator received another 30 min brick acid treatment, the left rad received 3 x 30 min of acid and both were left a long time with the garden hose running hot water through them. A lot of it hoping it will neutralise the brick acid.

The amount of c$#p that came out of the left rad was horrendous! Because the inlet and outlet ports are at an angle, I could not determine that this rad was shut. The pure water test that I've done to it did not dislodge any deposits so I presumed that it was OK. Check this out!



I have checked some pictures on the net and the coolant was blue in these pictures. I used pink and I do not remember how the original was. Honda gave me some Fuchs 50/50 low silicate blue coolant. Used that... Hard to think that the pink coolant did so much damage.

Late edit: Went for a ride, it heats up slower, 78°C most of the time. 78-79°C at 70 MPH, 79-80°C at 80+ MPH. Did not have the chance to hit traffic and seeing how it cools down from 98 to 80°C... see how long it takes.

Using the Transalp daily now so that I keep the Africa Twin and the C90 out of harms way. It does sit at 76-78°C nowadays... it's cold outside. Now, is it worth getting the rads off the bike and send them to a rad specialist to have them professionally cleaned? Or is this just another waste of time and buying new ones is the only way?

Give up and buy something air cooled...

How helpful am I....

I wouldn't in case the cleaning process weakens then further....


If it's working - fix it 'till it's broken....not always the best path.

I am looking in moving houses and will be a longer commute to work. I would keep the Transalp to commute on it. It's been proven to be a very reliable and good bike... besides me mixing coolants in it.. which is on me. It has 60 000 km now and still going strong. If I would have to buy anything else to commute, it would be a second hand bike that I don't know the history behind it. Decisions decisions. I will look at it when it gets warmer and it starts to run hot again. Or maybe it won't...
