Roger, glad you mentioned Ivan's findings as now I don't have to. I was surpised to see the dyno numbers compared to the 01-05. Horsepower in the restricted gear 1-3 only 3 more but that coming at 11,500 revs compared to the 01-05 coming at 9500. But the torque really surprised me with it being 10 ft-lbs lower and coming at a higher rpm than the older version and at 3000 rpm the 01-05 has 15 ft-lbs more. If you want an o6 FZ1 cheap, go to the FZ1 board, suddenly there are a few for sale.
Some advice to 06 owners. Don't waste your money on a power commander yet, because until a fix is found for the 1-3 gear limiter, it will only help you in gear 4-6 anyway AND will not be mapped for optimum performance until that fix is found. I am not in Ivan's "camp" as it were but do acknowledge his expertise in the 5-valve engine area and he will find a solution, just give him some time to do so before you spend your hard earned dough on a PC etc. BTW a can will help already because the cats are in the stock can and that losing that stock can gets rid of them.
You really need to ride the 06 to appreciate it. I think if anyone "needs" more power than this thing has they should have gotten an R1, Gixer 1k, Busa, ZX14, and so on. For that matter, nearly all the 600 and 750 cc crotch rockets are faster than the FZ under the right conditions.
To me the new FZ1 is krazy fast, so much so that I've let off a good 2 grand short of the red line (12,000) 'cause that was enough ...and that was IN first and second gear.
That said, this bike isn't for everyone, and that could be said for every bike built. I wanted something different looking, modern, reasonably comfortable, great handling, light weight, within my budget and fairly fast. The 06 FZ1 is all those things, and I am still amazed at just how fast.
Is it perfect? Evidently not, but I really think a lot of tuners are coming out of the woodwork to seize an opportunity to make some money. I'm okay with that but my bike is just fine the way it is.
Roger
