Hi, has anyone experienced waterpump seal leakage?
Waterpumps on have a small hole underneath in case of the seal fails, so the coolant wouldnt "stay in the system".
Well, on my bike, when high revving, i get a little coolant dripping out from this little hole underneath the waterpump.
I found this out today after a longer ride, when I leaned my bike, some coolant dropped on pavement , that was gathered inside bash plate.
Bike has done 18000km, so far no problems.
Will go to service on monday/tuesday.
What would be the cost of a new seal, I have no idea... The good thing is, I was about to replace the coolant anyway :P

New seal cost around 30�, haven't replaced it yet. well, crap happens

Yes I've noticed a small weeping of coolant from this tiny hole just enough to leave a stain on the bashplate no actual liquid is evident on mine.
Not sure if it is normal or means seal replacement is necessary.

Any experts ??

well the hole should be dry... so if you see any sign of leakage, at least my Yamaha centre recommended to change the seal...
