Topic: Anyone ever try the "Ultimate Flow Optimizer"??

[Pinhead]

The UFO is a simple, trouble free, aerodynamic piece that fits Mikuni carburetors from 30 mm through 44 mm. The UFO makes a normal round slide carburetor out-perform the more expensive flat slide carburetor by eliminating turbulence and increasing air flow and velocity, creating a highly atomized fuel charge. Normal gains are 3/4 to 1 HP per 100 cc of engine displacement. (Rejetting and tuning are required).

The theory is sound and seems like it should work. Has anyone tried or even heard of anyone trying these?

And what about the "Dial a Jet" system?

Its a bit like the Suzuki slingshot or a Powerjet system, only adds fuel above 2/3 throttle.
Works but probably overkill for stock engine/ road use

Some of my brother's buddies have the Dial a Jet on their snowmobiles. They sled anywhere from 1000ft above sea level to 7-8k in the mountains. If you need to tune for varying altitude a lot, or maybe like to switch exhausts and intakes around they'd be great, but probably not necessary for just riding around.
