I think the seller should just be honest with the buyer.
In any case, you have to be really VERY dof to sell your bike to another wilddog, knowingly hiding faults. Sooner or later the wilddog will pick it up, start a thread on it and then you feel like a d**s.
I am thinking of selling my one bike, I have not advertised it yet, because it needs some work. I have hinted in threads of people wanting a bike in the price range, that I may be selling soon. I have had quite a few PM's and I listed everything that was repaired, replaced, serviced to the persons requesting the information. I also listed everything that I intend to repair/replace before I sell.
I think the seller just needs to be honest and play open cards. This way he will have a happy future owner of his bike. There is no need to be dishonest and hide things that you KNOW is a problem or going to be a problem in the future.
It's all about integrity.
