Just purchased a 05 XB12R Firebolt, seems bike was dropped on side and punctured tank at one time, this was fixed but my fabricator friend wants to repair totally as there is small leak still . My problem is how do I get the tank sealant out with out damaging aluminum? I’ve asked around a lot and nobody seems to know! Were these Sub frames just replaced back in the day when damaged? Everyone I’ve found no matter price is damaged ( was going to buy one then fix it up for later swap) I’m up in BC Canada and parts seem rarer up here . Any help or advice on this would be great. I’m just looking ahead before I tear whole bike down for this, this coming winter.
