ah, piddle- live a little at the edge. smile. Fred is 100% correct--no residue can be present! We would all agree--it is not to be done by any redneck Hoosier (hey, watch this) but if you have it 'hired' done, it will be spendy. Prep time will be 10X+ longer than the weld time! I would ask for a quote before turning it over to them and then be surprised afterwards.... DISCLAIMER: I have never welded a tank, but have punctured many in farm applications and was present/helped to remove the gasoline residue and was onsite/present/involved when they were welded. Some shops will not weld a gas tank; others will say, "of course". Here are some of the things I have seen/been present when a gas tank repair occurred = when blacksmith shops were common in every little town (before the entrenchment of the disposable society). Of course: remove the gas! Shake/drain as much gas out of the tank as possible; IMPORTANT: let it sit in the sunshine to evaporate the gasoline residue. Then-- -drop some dry ice in the tank to displace any additional fumes, NOTE: if will not displace liquid gas! so as I remember (hey, watch this), the dry ice is in the bottom so the gasoline fumes will 'rise' out the top, etc) if the gasoline-fluid is fully removed. Time wise, it happens very fast. I watched them drop in the dry ice and almost immediately go to welding. shrug. Others did this: -route the exhaust from your auto directly into the tank = 30 minutes.(min. 10 minutes is what most will do) results = same as dry ice plus the added 'benefit' of the water vapor....(no, the water vapor is NOT a benefit, but a side effect you need to know about.) Another welder-- -filled it with water, cough. = Welded with water in the tank. Another filled with water, drained the water THEN cleansed with auto exhaust/dry ice or -JB Quick (as previously discussed) NOTE LIQUID STEEL, etc, Did not work well where rocks were bouncing against the automobile fuel tanks that would drag on gravel roads, etc. -Let 'Mikey' do it.... If you use any method that includes water/engine exhaust; You will want to 'HEAT' treat your tank for residual water afterwards...others will need to comment on the effects of HEAT on the KLR performance etc. Those with extensive welding experience should comment as well-- Note: there is a degree of risk involved, but can be minimized through careful preparation. For the faint of heart; JBQuick (following J Koury's) full instructions are 4.0 and will most likey exceed your use/life expectancy of the bike. of course, all of this advice/experience is 'at-your-own-risk' etal. revmaaatin.
