Hi guys. I'm new to trials and also new to this forum. Maybe I should do an intro first but just a quickie for now. I recently picked up a Beta 270 rev3 2007 model and soon found out about this corrosion problem. Well, 2 months later I decided to inspect the pump, the previous owner mentioned something about the previous owner having checked it but I decided to know for sure. Immediately I was very surprised at the lack of damage, there really isn't much to speak of apart from some of the paint having come loose which I cleaned up but there's no pitting at all. Was I just lucky with this purchase?? or possibly the right coolant has been used all along. I also managed to get a pic of the piston surface through the plug hole, possibly need to de-coke at some point. The piston from the exhaust port looks a little scratched too. Otherwise the impeller is fine which is the main point of discussion. Looking forward to chatting and I'm sure I will learn a lot here.
