R&D adjustable cam gears!
who else got the e mail?! Look NICE:
R&D YAMAHA FZ/FZR/SHONew Product Release
ADJUSTABLE CAM GEAR KIT
PART # 612-93008
R&D’s Racing Cam Gear kit allows a huge boost in overall horsepower to be gained by custom tuning the camshafts LCA (lobe separation angle) set up. Tuning the LCA with R&D Pro Tune Cam Gears can add 200-300 RPM’s, increased boost pressure, and 2-3 MPH to your existing engine package. Adjusting the camshafts LCA is a very simple “BOLT IN” modification with the R&D Pro Tune Adjustable Cam Gear Kit. Understanding the LCA concept principle is fairly easy. A wide LCA like found in the SHO and FZR will generally result in decreased valve overlap, later intake events, earlier exhaust events, and high intake manifold pressures which produce great idle, smooth accelerating with mild low and top end power. Wide LCA’s are great for school buses and soccer mom vans.
However, if strong mid range pull and top end horsepower is what you’re looking for, then a narrower LCA will need to be generated. The R&D Pro Tune Cam Gear Kit allows the LCA (lobe separation) to be adjusted narrower which will generate increased valve overlap, earlier intake events, and later exhaust events. Resulting in snappier throttle response, increased mid range and top end power and more boost. Why spend big money on optional camshaft kits (i.e. 1800 N.A. cams) that have proven to offer too narrow of LCA compromising idle tune? Buy the R&D Pro Tune Cam Gears designed specifically to improve overall power at a fraction of the cost and provide an optimum overall tune. The R&D Cam Gear Kit offers four possible LCA combinations that allow the cams to be tuned depending on the type of riding or racing and type of fuel. In fact, R&D has built a specific engine designated for degreeing, checking and proving camshaft specifications. Depend on the Pro’s at R&D to deliver all your horsepower needs.

So no additional tuning required for these? Need much more info. Sounds great from the description, but most parts do sound great in the manufacturer's write-ups.

I won't be getting them anytime soon.
Billet/ground cam gears - The OEM gears are heat treated and I'll wait to see if these hold up and are worth it.
"similar to a 1 pound boost addition" - Not worth it IMO at least right now.
Ya'll need to go take a look at what Riva has added today!
