bigdog04, Those people that we see on TV welding on motorcycles are not welding on completed motorcycles. I`m sure that you understand this. I am a welder by trade and being an Ironworker IMHO it isn`t worth the risk at all. On my bike there will not be any arc`s struck under any circumstances! Disconnecting the battery and grounding close to the work is NO insurance against damaging the electrical systems on your Big Dog! There are circuit boards in the handlebars, turn signals, and other systems on your motorcycle. It`s like Clint Eastwood says in "Dirty Harry"; "Do you feel lucky"? I wouldn`t risk it myself. If you must fabricate a custom exhaust system - do it off of the bike and fit it to the engine after the tacks are made. IMHO. Electricity can and will travel in strange ways some of which are not predictable but cause considerable damage. As for my part it just isn`t worth the risk; It`s your call bigdog04.
Tom Chop :choppersmiley:
:iagree::iagree: These guys are right. Not worth it. I TIG welded one while I was at the dealership. I told them I should not , but they insisted so I did. I had the battery disconnected and the ground close and it still ended up burning up the speedo/tach and wire going to it. If you must weld on it I would remove your fuel tank and unplug all wiring. I have even talked with a guy that welded on his drag bike frame and come to find out, when he tore his motor down, he found that there had been an arch from one of the rocker arms to the top of the valve. Does not happen all the time, but can.I agree with Tom Chop, I also welded for years. The electronics on these bikes are just too sensitive. Don't think I would risk it. Remove the part if possible before welding. If you using a Tig to tack, that high frequency start interferes with a lot of electronic shit.
