I put on a Vito's BB Kit on my 06 blaster. I even upgraded to the forged piston. I have rejetted the carb. It now has a .340 main jet and is in the middle clip on the pin. I got rid of the oil injection and mix my own oil at 36:1. K&N airfilter no lid. It lasted about a year before melting the exaust side of the piston. Obviously i will have to rebuild but any ideas on the cause?
