I did all the mods myself. Paying someone else to do it all would have been astronomically expensive. . . . Nothing was particularly difficult. The sprocket change is simple conceptually but requires the correct size very large socket and is best done with an impact driver. The FCE requires a...

Ken, I have already said my piece on the Autotune and actually a good bit on Beast's perspective. Feel free to drive on up to Silver Spring, MD if you want to experience how well TPS tuning can actually work on my 06 with its "untuneable" ecu still in place. . . .

It is important to keep in mind that the setup that Mr Beast is advocating is not simply using the Autotune with the the PCV but also involves the LCD unit, data logging and MAP based tuning. The extra hardware for this is expensive stuff and most definitely has a steep learning curve for its...

A FZ1 with the "full mod package" will make more power than a stock R1 throughout all but the highest portion of its rev range. The path is laid out for you here and on the other FZ1 site. Do some searching and reading. Here's a good thread to get you started: Full Yosh system tested-dyno...

No issue here with 1000's of miles on a heavily modded bike. Speedo DRD too. (it will be interesting to see if it is the culprit for Geno) Don't agree that the FZ1 is well sorted out from the factory. Incredibly restrictive intake and exhaust, poor fueling, snatchy throttle, junk rear...

Beast what does you saying "untuneable" really mean? Would you like to ride my "tuned" 06? How about Mr Duken's tuned machine or any of the many other ones out there in FZ world. Are we really completely deluding ourselves to how well this platform can perform with the hardware and maps and...

Didn't you send in your 06 ECU for a reflash and sell your 10 ecu because things weren't good enough? Didn't you sell your FZ1 too?

Fuel cut is still there and can be very detrimental to handling particularly when leaned over and reapplying the throttle. I have logged some decent seat time on the 10. I also do have strong memories of the snatch before I modded my 06. Can't say that it was much worse than my buddies 10...

How much improvement do you really think the 08 ecu (or 12 for that matter) is really going to have? Fuel cut and associated snatch is still there. I have ridden my buddies 10 and it's still annoyingly apparent.

New ECU? Gotta say beast that this is B.S. There are plenty of us happily riding around with the stock 06 ECU. The FCE will get rid of the snatch (that is still present on the newest ecus)and all years of this bike need some serious hard parts to really shine. Perhaps you should just ride a...

Here's a couple of charts from Ivan for the "full package" versions of the GenI and Gen II. (GenI on the left GenII on the right; REAR WHEEL HP) No guarantees for exact same conditions but the dynos are likely the same . . .Both are pretty impressive with the GenII winning out on top. The full...

Secondary flies are from Ivan's Performance Products along with the FCE and map for the Power Commander. There is plenty of reading to be done on the flies and other performance modifications for the FZ1. Check out the archives of this and particularly the other site (yanahafz1oa) The...

Rizoma's are billet tubes with rubber overlay. The Driven D3's are actually rubber with billet collars that slide over. I have both on different bikes and the Driven's are definitely more comfortable. They are, however, more difficult to install as the Rizoma's are a loose fit until you...

I would guess that long term motorcycle riders could statistically be shown to have fewer accidents in their cars (car miles driven compared to miles driven by non riders). Overall, one of the largest populations of MC riders in the States are young men riding sport bikes. I would guess that...

Ok I'll bite . . . . Why are you replacing your impeller??

Charging system draw could certainly be the cause. . . .You also might consider that when you grab the brake lever you are clamping the bike more rigidly to its resting spot. The front/back wheel have a certain mass and that becomes more directly connected to the rest of the bike when the pads...

To each is own but that CF just makes the stock setup look even tackier IMHO. That 125hp is way on top and in stock form the bike is downright anemic in midrange. Stock bike makes about 75hp at 7k with less than ideal fueling and throttle characteristics (particularly the early bikes). A...

The stock pipe's sound? I personally like a quiet pipe so yes I do like the sound from the stock pipe . . . . Not much else to like about it however. Ponderously heavy, bulky and restrictive. Stock header is also heavy and its tubing length is compromised to fit the second cat. . . The...

The optics on the stock headlight assembly are not optimized for HID elements. Cutoff will be less defined and you risk blinding and pissing off oncoming drivers. Not a good idea IMHO. Also most HID retrofit jobs offer overly bright light in the area immediately in front of the bike causing...
