    GX 140 emulsion tube

    Yep I've seen those modified E tubes on 4 Cycle too. Here's a picture. Silver solder would work pretty well. Of course it's only a $7 part or $15 if you want a genuine Honda.

    Hey thanks Fabroman Originally I was going to use 25mm x 25mm x 1.6mm but the guy at the steel suppler suggested something thicker and I’m glad he did. It was easy to weld and you know you’ve got plenty of penetration.
