Weird coolant leak

Hi all
So my bike is on the dyno and I got a coolant leak. Fairings were off so I found the culprit immediately. It was from the hose coming out of the crank case. Thought it was a loose fitting so I replaced the clamp.
Another dyno run and it did it again.
Iím noticing a little bulge in the hose right under the fitting (see pic). Rest of the hose is fine and itís only happening on high revs.



No overheating
Dyno fans on and no issues with engine temp.

Any ideas?
Pressure buildup?

Had coolant recently flushed and replaced with no issues at all.

Help

Try repositioning the clamp. I just changed coolant in the Daytona and drained it from the bottom of that hose. After reinstalling it leaked. I repositioned the clamp and it stopped. I asked the service writer at my shop and he said leaks like that are frequent and if repositioning fixed it then I should be good.

Already did that and replaced the clamp altogether and yet ...

Funny...

Last night I was replacing oil and filter and when I was removing the filter with one of those universal oil filter removal tool (the ones that have bulky lugs that clamp the filter) I ended up nibbling the bottom of that same hose just above the lower clamp ... Didn't see any leaks when I ran the engine to check for oil level / pressure, but I'll have to keep an eye out for any leaking coolant...

Worse case I'll end up replacing the hose.

How much do they cost?

Life's so much better on a bike!

Mine was literally barbecued but the exhaust. On the dyno the air flow is less and the headers were glowing red. Too close to the heat and no air flow. The hose couldnít take the pressure. Iím just glad it didnít pop that would have been a disaster.
Not sure about price but hoses are usually cheap. I will install a similar one from Kawasaki and cut to length. Canít get my hands on a Triumoh one for now.

That same hose popped on mine, except it happened to be on the track topped out in 6th gear. Itís a bad hose with a bad clamp.

Replaced and ghetto heat shielded. Looks crappy but it will stay put and protect that hose!


Recommend doing this for every D675 going on the dyno. Better safe than sorry.

I found it on this website... I think it's part reference 16.

https://www.worldoftriumph.com/parts...100062002-0-2/


About €15.47 (plus postage) in the UK / EUR. So I'd say it will be around $35 AUD. Mind you this is for the Street Triple R, but should give you a reference for the D675. And you can fish around on that website for whatever you want.

Thanks.
Am aware of the WOT website. I get most of my rep parts there.
This was a different issue and I needed a replacement on the spot so I got one for cheap at Kawi where I was tuning my bike.
Solid fit and match no issues.

Next service: Samco hose kit.
