I did this mod, low end riding becomes better. Can felt engine slightly softer and the exhuasted air become stronger. Try at your own risk.

How does High-RPM performance feel? Interesting idea, that's for sure. I'd need to see some dyno curves to see if it's really worth it though. At least it's an easy experiment.

I have not tried high rpm yet. Maybe you can post the dyno result for this simple mod.

Which method did you try? Connecting all four carbs, or 1 to 4 and 2 to 3?

It appears the FZ1 must get its vacuum signal for the petcock somewhere else as they don't mention a tee for supplying a vacuum signal to the petcock.

Seems a cheap and easy mod that's easy to reverse if it doesn't work out.

Jay, sounds like you've tried it and didn't like it, care to elaborate?
