jas Posted October 18, 2015 Report Share Posted October 18, 2015 I have a couple broken fins on a Mono cylinder, I'd like to repair them but I'm not sure if the parent material is aluminum or magnesium. I know the side covers are magnesium but not sure about the finned cylinder. If anyone knows which it is, please let me know. Thanks, Jim Quote Link to comment Share on other sites More sharing options...
dadof2 Posted October 18, 2015 Report Share Posted October 18, 2015 The fins are weldable with TIG and 4043 filler, unlike the side cases. Quote Link to comment Share on other sites More sharing options...

biffsgasgas Posted October 22, 2015 Report Share Posted October 22, 2015 It's aluminum head. Cases are magnesium. When I was a kid has me sidecases welded in an an anxious argon chamber. --Biff Quote Link to comment Share on other sites More sharing options...
