pschrauber Posted March 19, 2013 Share Posted March 19, 2013 welding or brazing the leak area is the best solution. As a workaround depending where the leak area is you might put glas fiber cloth underneath the area and wrap wire around. (this "solution" will not last long ...)

cvgmmartin Posted March 19, 2013 Share Posted March 19, 2013 If it is just a crack you can actually seal it with solder and it will last for a while assuming you don't need the solder to provide any structural strength. It doesn't get hot enough to melt the solder. Quote Link to comment Share on other sites More sharing options...
smelling123 Posted March 20, 2013 Share Posted March 20, 2013 Even some silicone sealer (from halfords - not the bathroom type) will seal a small hole. Quote Link to comment Share on other sites More sharing options...

old trials fanatic Posted April 3, 2013 Share Posted April 3, 2013 If you do have to get it welded it would be best if you do remove from the bike as "electronic" ignition is very easy to damage when any form of electric welding is done. Then of course there's the collateral damage to the bike but it's up to you at the end of the day. Quote Link to comment Share on other sites More sharing options...
