So does anybody know for sure, are the newer, bannana seat, f4i motors less powerful than the older.
Ive heard the newer motors are toned down, compared to the older.

If so how much difference, and in what aspect (low end, hp, ect).

Im about to buy 2006 non-cali motor with 850 miles on it, but it does have o2 sensor which I was going to remove and put a o2 elimiator in place.

ANybody heard anything bad about removing the o2?

 

Back to the top!

i searched for an hour and a half earlier and got mixed answers

I know somebodys got the lowlow on this

 

why do you want one with a banana seat...why not just buy an 01 or 02

 

nah , i have a 02 already, i thinking over buying this 06 motor.

-I heard they were toned down in 2004, something to do with the ecu, or honda trying to make the 600rr more appealing by making its dyno numbers look better, ect..

-Ive heard the cali models were weaker unless you took the o2 sensor and emmission crap off

-also heard if you disconnect the o2 sensor and put the o2 sensor eliminator in that it will make you always run rich


u gotta to take everything with a grain of salt, thats why i posted up, trying to get to the bottom of this

 

If its just a ecu programming thing don't worry about it just use the 02 ecu. The ecu and motor will never know the diff.

 

I have an 05' and an 01' ...and the 05' seems to pull quite a bit harder

Could be because it's brand new and the 01' has been beat since day one. idk


I've heard the "newer less powerful" story before and I'm pretty sure it's a crock o' ****.

If you really want to be sure just get a ECU from an older one and swap that out... my opinion is it's a waste of time... my **** pulls as hard as an f4i is capable

 

ive heard the 02s and above have 88 hp to the 01 101hp.....dont know how true it is though...i'd just add more gearing and go make wheelies.

 

yeah ride on brother

 

there the same, and Im pretty sure only cali models have the O2 sensor

 

Ive also heard this about the 01 being the strongest of any year

 

i have an o4 motor in my 01 f4i and it seems the same

 

from what i understand all the 06's have the o2 sensor, ol boy who has the 06 motor is from a virginia bike.

but the the cali models have the o2 sensor, the canister, and all the emmission junk

 

I had an 03 from TX and it had a hole for the 02 sensor in the collector. I had to put a coke can and one of those hose clamps around the pipe to keep it from making a stupid sound and blowing exhaust in my face.

 

could be.... my buddie has an 06' and it's not a cali bike, but it does have the 02 sensor.

 

just throw a bolt in there, but whatever works

 

I didn't feel like going to Lowes and I had some hose clamps laying around.

 

my bike is a 49 state bike and all my friends have the cali bikes and they say my **** runs better then theres

 

I have a cali gixxer and it seems pooey.

 

I would think they are the same, why would they need to tone them down they are gutless already.

 

i have an o5 gsxr and it doesnt have a o2 but its got the canaster bullshit sorry to get off topic guys
