Has anyone put vm32 carbs on a GS 450? I have put them on mine and played with the jetting and it's very close to perfect but I wonder if anyone has found the perfect set up?

There's only a couple people here that have GS450's, and I don't recall anybody in particular using VM carbs. There might be somebody over on Dotheton.com or on GSResources that has done it.

You might look for somebody running them on a CB450 and look at their jetting as well.
