Impossible.Perhaps it's flowing more air, and at lower rpm's/speeds it makes a tiny bit more torque than before
I did a TBS this weekend and it did help a little. I put the stock filter back in and It did help the issue some. TBS 20% filter change 40%. I have been running regular gas and plan to go HI test for the next tank and see if that will help. Maybe Santa will leave a power commander in my stocking this year.In an already "lean" situation, more air now means even more lean... Power Commander or Reflash time... Oh, and have you sync'd your TB's? :cheers2:
Of course it does because these bikes do not have a MAF or a MAP and North American bikes no O2 sensor to regulate pulse width on the injectors. We run on a TPS and it only knows to put a given amount of fuel at a given throttle position. So if one air cleaner flows better and allows more air to pass it will be running leaner. That also hold true if the stock air cleaner is more restrictive, it will allow less air to flow resulting in a richer condition. There is no way for this bike to adjust the air fuel mixture. So that's why people hack into the FI system with a PC111, Yosh boxes, etc.Impossible.
The throttle is regulating air flow depending on how far you twist your wrist and pull the butterflies open. The air filter has zero effect on air flow until wide open throttle and high rpm--if then (and I don't think the brand of clean air filter makes any difference).
here something to read about the K&N myth:
Debunking the K&N Myth - Why OEM is Better : Nissan Articles
If you need more reading, search for "airfilters, intake air, intake air siting" on Browser Warning
K&N is expert on marketing!
Reading their website EVERYTHING makes perfect sense and you can convince yourself just right - no problem! Did it myself!
After checking into the above mentioned sites - I woke up!
Okay - the K&N flows what? - 30% more??
When do you really need that flow? Maybe really at the very top of your powercurve - until then your OEM will flow just fine - it is made to flow enough to make that top power.
How many times to you really need that top-end power??
Are you always revving to/past redline??
Once you find out that the airfilter is the least restrictive part in your intake system - "30% better" becomes near meaningless:
How much better flow of the absolute restriction is 30% better on the 2-3% restriction the OEM filter causes?
Or said the other way around: With your K&N you have only 2.1% restriction instead the OEMs 3% ......
Then, if you read in detail: Your K&N has to get quite dirty to even start some decent filtering - meaning, it needs dirt to plug up and so catch more dirt!
Last - how many OEM filters can you buy for one K&N?
Besides, IIRR you can clean the OEM to some degree too.....
Today, the only way to filter is to put restriction into dirts way (well, there is other means, but nothing that even would fit on a car, let alone a bike).
I'll go back to OEM and better filtered air...
