Expansion tank leaking coolent.....

OK, did as you said, took a little sample of oil from tank, looked a bit cloudy. Also, when I looked at expansion tank with flashlight, I saw a few chunks of rubbish( poss. seal bits?) that were not there before. With that, I assume it's time for the rebuild seal/shaft kit. The link on a re-build from adventure site is same as 07 superduke? thanks for listening to me chat with myself. Very new at this moto world, and engine knowledge is zippo, but going to try myself. Maybe!!!

The water pump is the same as far as i know. I have done many bikes water pumps before, but not the SD. Follow the right up and you should be fine.
