Tomcat,I did not intend my PM to you to be "smatarse" I read it carefully three times before I sent it. It was in response to your "shouting" in bold print out of my screen "send me the fu$king pistons". I described what I had done to send you the pistons.If I offended you I apologise. Copy and paste the PM and post if if you wish. I was probably rude to your mate. If he is the guy I think he is, he rang me for free advice. He had bought some cams from an american supplier and wanted advice on the fitment etc, and numerous other things. ( it is a while ago).I asked him why he did not ring the US men, he said they would not talk to him. I gave him some advice, then he told me why what said was wrong. I spent , I reckon , three calls at about 40 mins each with him. He was always careful to ring at 5.30 pm when most folk go home. He ignored my advice , which is why his engine spat a shim and crapped itself,when he started it up. Then he rang me again and by this time my patience was exhausted. So I was pretty blunt with him. He wanted some valve spring retainers, which I did supply him, but only with springs to suit.My reason for that was so he would not have further trouble using mismatched parts. I also directed him to a GOOD guy to tune his bike. Maybe this is the same guy?
