    Why not use an even bigger, naturally aspirated engine?

    Think Vxr or fz with a bigger engine. Shouldn't an NA engine big enough to only get the gas mileage of the current fz yield much more performance? (based on the fact the vx and fz are close)

    I think someone should do a FZS2000 swap....2.2L naturally aspirated puts out 250hp already has a 8k redline 9k if you use the f20 from the 00-03 models and if you turbo it can put out however much power you want it to....like 700hp haha...

    Probably too much weight for a larger engine. Plus, Yamaha specifically designs their engines for marine use so they have to meet certain specs on size, weight, etc

    I think what Yamaha has done with this engine is already pretty amazing;
    1812cc, 4-Cylinder, 4-Stroke, Supercharged, Intercooled...

    Hondas never came close to this performance and left the market. Kawi has raised the HP bar with its 300, but most of the guys on Ultras we ride with can barely afford to put gas in them as it is. Sea-Doo's Rotax engines are not as durable. The industry is struggling just to survive in this green-minded economy.

    There's always room for improvement, but I'm pretty happy with the engine Yamaha is bringing to market; the engine is awesome. Heck, the engine has already put the VXR way ahead of other NA craft. If anything, I think Yamaha should invest in other areas; like maybe improving the pump, off throttle steering, ergonomics, etc. on their watercraft.
