Here is how I'm stabilizing my carbs. 1/8" titanium rod and titanium tabs added to the mikuni float bowl. Upgraded the screws to stainless. I'll also get better bolts on the clamps. The titanium rod is easy to form if you get it red hot. I use a small butane torch. This seems like the lightest solution i could fabricate with the material on hand. I've got a good scrounge pile.
