section swept Posted July 22, 2020 Report Share Posted July 22, 2020 Well you could try the internet or have a look at your nearest industrial area and try to find a good aluminium welder. The original Montesa alloy tanks will be very brittle especially in any repair areas. Some people have tried various sealants and plastic metals but they invariably leak fairly quickly. Preparation pre weld will need the tank steam cleaning or filling with exhaust fumes, neither of which are truly safe for welding a petrol tank. I have had race car alloy tanks cut and modified and then re welded....but I went into the next county before any welding action took place. Good luck, I am not too far away from Metmachek who make alloy swing arms, specialist race parts and they welded a Bultaco flywheel cover for me...I coughed when charged £40 for a 1 inch weld..hope you find a reasonable cost.
