Has anytone had any heli-arc welding done on any motorcycle? what where the results? I am thinking of welding a small stud on my waterpump shaft. will the voltage damage any thing? bigbiker@...

[Dave Watkins]

This just in from "The Great White North", Where welding is concerned I've always understood that the current will take the shortest path from the electrode to the ground. I've welded on many vehicles with no problems at all however I always disconnect the battery before I do so. Place the ground clamp electrode as close to the point you are welding and go for it. It's probably a good idea to disconnect the CDI unit as a precaution. I'd make sure the tank is covered with a wet towel just in case...... Have a fire extinguisher close by and do it in the yard, not the garage. Cheers, Dave Watkins 1998 KLR 650 " The Prodigal Son" Calgary, Alberta, Canada dave@...

I just welded a small bracket on my KLR650 frame. I did just as Dave Watkins suggested in his Post. I put a soaking wet towel over the tank & seat & put wet rags all around the area I was welding to catch the hot sparks, etc. I disconnected both the positive & negative battery terminals & isolated these terminals so the didn't contact the frame. Made sure there was no leaking gas & also had a fire extinguisher at the ready. The bike started & there were no problems with the ignition or charging system. As for welding the water pump shaft, I'm not too sure about that. Pete A16

I haven't on the KLR, but I have on other bikes with no problems. General rules, however, try not to ground through a joint, and NEVER through a bearing. Your grounding electrode needs to be connected directly to the piece you are welding. If I take you literally about welding to the water pump shaft (the rotating thingy), you need the grounding electrode on the shaft and NOT the engine/pump case. Running current through a bearing surface, or bearings, can damage/destroy them.

He's probably concerned, and rightfully so, about the high-frequency start from the stinger. It's in the radio range. Jake

I know this is an old thread but when I searched on "frame" and "weld" it was the only thing I found relevant. I've got a broken cross brace on my KLX650. It's under the fender and is where two of the four bolts that hold the rear rack are bolted to the frame. The cross brace doesn't seem to be too critical and I'd probably only loose my tail pack if it were to break. All the same, I'd like to fix it. I've got a 110V MIG but I'm by no means a welder. If it were a KLR, I'd take the subframe off to weld it but since the KLX frame is one piece, I can't do that. I plan to remove the battery and tank prior to tackling this job. Am I likely to fry anything electronics? (Frying my hand is a foregone conclusion) Any words of wisdom? It's been two years since the last update to this thread. Thanks, Ray Calgary, AB

The only danger is from heat or "flying slag". Welding the frame should not harm your electronics, provided they're not in the immediate vicinity of the weld.

If you can shield nearby wiring etc. with a bit of light sheet metal, it should reduce the problem of barbecued wiring or other bits that might melt. DC scott quillen wrote:

If it's what I think your talking about, it's normal. The only thing your saying that doesn't fit the description of what I have heard (and many others) is that you hear it even though the engine rpm's change. The hammer sound that I hear is very distinct when you take off from a stop and your lugging the motor a bit, or if your just sitting or standing next to your bike and you blip the throttle, you can hear it "hammer" just once or twice really quick before the rpms go up. This sound has been heard and voiced many many times before. It doesn't sound right, but it's a KLR signature and nothing to worry about at all. Mine has been doing it for over 46,000 miles.
