For the seat, check with the fellow in this thread. MORE SEATS - FZ1OA Message Board He should be able to customize the seat to your particular needs. BTW, you will need to join the other forum if you want to see the pics . . .

Just for comparison. Here's his chart for the "full package." I'm sure he is using an upper unrestricted gear for the tests. Note the additional 30hp (over stock in previous chart) at around 7.5K. Results with his flash should be a bit better with no lower gear restrictions(of course, still...

"Correction" would involve applying a factor to the results to adjust for differences in air density from one test to another (whether it is the same dyno or any dyno anywhere in the world) Air pressure and temperature will affect the air density and can have a significant effect on power...

Most of the tuners and magazines work with rear wheel HP figures. Motoraad is using crank HP figures. Apples to oranges. Here's a chart from a somewhat recent test by Sportrider: http://www.sportrider.com/bikes/146_1108_kawasaki_ninja_1000_suzuki_gsx1250fa_yamaha_fz1_battle/photo_08.html...

I can just about guarantee you that the European bikes make essentially the same power as the US bikes. Can you link those dyno charts? . . ..Dyno's vary significantly (even the same model dyno) as do the conditions under which the tests are made. That said, it would be a have to be a...

The full yosh R77 system can give a nice midrange boost in addition to gains at the top end. The stock header is a compromise design to fit the cat so even gutting it and installing a slipon will not net the same results (softer midrange) than switching to the full system. "Titanium" is simply...

Crikey! YES THE BIKE IS RESTRICTED IN LOWER GEARS. It is a combination of timing and secondary throttle plate control. Stock bike makes about 125hp at the crank. A "full package" bike (see my signature for the mods) will make close to 150hp. Its by no means all high RPM gains either. Full...

FCE's primary effect is to eliminate the fuel cut on deceleration. It also is reported (by Ivan) to open the secondary throttle plates more quickly. It does nothing to the stock fuel mapping which is much less than ideal, particularly once you add intake / exhaust mods. Had you installed the...

How different were the maps for stock air box vs the modded one?

Ivan's charts show gains of around 3hp starting as low as 4.5k rpms. That is a fairly significant gain in that all important midrange. The test mule (for both runs) had a slipon, fce, pciii, and ignition module as well. Presumably the mapping was optimized for both runs. Hopefully Ivan will...

Here's a thread started by Ivan showing the differences he found with the airbox mod. The differences are a good bit more significant than what you found . . . .Ivan's results - Airbox mod and BMC filter - FZ1OA Message Board

To each is own . . . Although I certainly enjoy the increased power (throughout the rev range) that mods have given my GenII, it is the dramatic improvement in the QUALITY of the power delivery that makes them most worth while. Delivery is smooth and linear and worlds better than what Yamaha...

What generation of FZ1? What mods do you currently have?

There is plenty of info on this site and the other one about modifying the GenII for performance. This bike has been around for eons . . .If you search and read up you will find that with proper mods there is nothing but gains to be made in both performance and driveability. You are worried...

Semantics? Who really cares except that it is confusing . . .but . . . On the reflash it's not an "eliminator." It's the removal of the fuel cut from the code, presumably at the source. Ivan's FCE (which works very well) tricks the sensor(s) into thinking that throttle is not fully closed and...

PK, Thanks for the clarification. As Whittlebeast mentioned some others who have had the flash done (and requested the removal of deceleration fuel cut) did not end up having the fuel cut removed. This was verified in testing and at the time ECU unleashed was unable to correct the problem...

I'm confused . . .In your earlier post you say that the FCE (Ivan's fuel cut eliminator) was great? Overall, your dyno results look similar to plots I have seen for similarly modded bikes with the stock ECU and proper mapping on the PC. This is not to say that what you feel on the street...

A couple of questions for you PK . . . What's the complete list of mods on your bike? Why should you need the FCE after the reflash? ECU unleashed has always claimed that the reflash elminates deceleration fuel cut. Some reports have shown that the fuel cut is still there after the...

Actually my gut tells me its more like 95% but in the end I can really only know what I experience every time I get on the bike. Perfectly smooth and linear power. There are no hiccups, and as best as I can tell there are no adverse effects to the temp ranges that I ride in (40s to 90s)...

Beast's map is for a system using the autotune, and MAP based tuning. It will not be appropriate for your proposed system using just the PCV. For perspective, the PC has been available for the GenII for nearly 6 years. Thousands of maps have been created for just about any combination of MODs...
