Golden rule is not to enter into any protracted correspondence with him as you could inadvertently give him ammo to use. Having recently helped out with someone else's litigation you do have to tread carefully it's amazing what can be thrown back at you! I would send him an e-mail pointing out that it was a private sale therefore no warranty is applicable, and that he had adequate time to inspect the bike and he should have sought a qualified opinion if he wasn't happy. You then need to end it by stating that you now consider the matter closed and you will not enter into any further correspondence. If he then sends anything else keep it however don't reply.

I have had a similar situation with a BMW I sold a few years ago which broke down with a failed alternator on the blokes way home. I agreed to pay half of the cost of the part out of good will and sent him a cheque with a letter stating just that.

Anyway good luck, let us know what happens!
