Actually to be honest I don't now and never did except for the one time when I was around ten years old and mom cured me of that one right fast! Another thing is I too cheap to pay that kind of money that could be better used on motorcycle parts or micro brew barley soda!Hey I have a 1978 with a leaking petcock on left side would this be an approved repair form me I don't always smoke while riding and my plug wires only arc a little on damp morning!
Best of british luck there Beags.... been my experience that pinholes run in herds."Houston, we have a problem..."...

...by my count one too many holes here.
Been chasing a minor weep around right side petcock. After multiple tries changing this that and the other a bit of poking around with a pick discovered a pin hole hidden below the paint. Small bubble in paint led me to the discovery.
Trying to avoid a liner if at all possible so looks like a thorough tank flush and wash is in order. Surrounding metal seems sound so going to do my best to TIG this lil bugger closed. Nothing to loose at this point.
At least it's in a spot that's easy to hide a repair.
Never did it on a bike tank... but I've fixed more than one lawn mower tank with 5-600° silver solder and a propane torch. At that low temp the rest of the "herd" stays hidden. If the tig makes more holes, might give it a shot?Oh I know, fixin' one generally breeds two or three more...okay maybe five. Gonna strip the area around the petcock flange and give it the once over, see if I can spot any more.
Push comes to shove I'll line it
Well there ya go then.Always a possibility too. Soldered a joint or two in the last 35 years of my plumbing/HVAC career
