Good day gentlemen.
I have a 2005 SV1000S, 53,000 miles, I'm the original owner and have done most of the maintenance myself, bike is garage kept (so not exposed to sunlight or elements) and pristine condition.
Removed fairings to replace head bearings and noted the radiator hoses have this sort of whitish "coating" -like condensation that then dried out- over them.
Is it early porosity or a sign of impending leak or failure...? Or what does it mean?
How long to these hoses last...?
Getting to some of the hoses around the thermostat looks like a nightmare of a job...
Do you guys ever replace these OEM hoses at some point?
Whats the longest (time or mileage) you can go with them...?
Thank you very much for your advice!
Daniel

I have 336000kms on mine, and the hoses are original, except the thermostat hoses....one swelled up and burst about 15000kms ago.....i would say thy are at most risk because of the heat that
is directed from the block. You remove the throttle bodies to get to them.....not difficult, but make sure the engine is hot when taking the throttle bodies off as the inlet flange rubbers wll be softer
and more compliant. The white powder, might be the detergent you are using to wash the bike with ?

Get the Samco silicone hoses if you can. I have a 2003 I bought on January of '21 and I immediately replaced the hoses that go to the thermostat as well as the metal tubes they connect to that bolt to the heads and the o-rings of course, yes they had all the white powder all over them, the reek of coolant that was coming from the vee of the engine has been conspicuously absent thereafter. I did not need to remove the throttle bodies when replacing those components. The rectifier will need to be removed to gain access to that space from the side of the bike however.
