I have a crack in the frame that needs welded. Is it safe to weld with the stator and other ignition components still attached to the bike or do I need to remove them? The crack is in the weld at the downtube / headstock joint.

 

 I welded the same spot with no issues. It`s held the last two years and I`m a crappy welder.

I think the question is will the ignition suffer due to the welding not will the weld work.

To be safe I would always remove electrical components if using an electric welder, far cheaper to be safe than sorry.

If you can get the earth clamp from the welder next to the weld it's safe,but if not remove the electrics

I meant I had no issues with the electrics. Never seen anyone disconnect electrics for a weld job if grounded properly.
