Things are just Different. Even engines coming off the same line are different. The manufacturing variances in every part add up to make one engine a bit better than the rest. Try swapping air filters with Dad & see if that changes who wins. Maybe its the fiklter, maybe its, you got a faster bike?

I havent changed mine yet but Im looking into one of these(see the link) I got one for my 4runner and I love it.  only thing is it will have to be a pod type.

OH YA and Savage_Amusement's 10mph over on me is about to go byby  

I can say this much.  The filter on my bike was a significant change.  I do believe that k & n makes claims that are highly inflated and that is what they are always going to do.

My bike is an 05 and I rode it for the first two years completely stock and could never go over 85 mph but the throttle was had a lot more and it wanted to keep going.

I took out the spacer completely and did the screw adjustment to 2 turns out.  This made an enormous difference.

However, when I added the K & N to the mix after all of the above, my bike was then able to easily break the 85 mph barrier to 90 easy and at times, depending on wind resistance and temperature 95-100.  The filter made acceleration a lot quicker along with top speed.

The problem with k & n filters is that I have them in all my cars and do notice a big difference in throttle response and that is it.  No mileage difference or acceleration.

When putting one in a very small engine like the s40/savage, that little difference it makes in a big car engine turns into a big difference in a small engine.  

One other thing that really helped my bike in the extreme heat of Arizona, was to put all synthetic oil in.  This made the engine a lot cooler after riding, made the engine quieter alltogether.  It also helped a lot in acceleration.

I have changed my oil with synthetic twice and evertime I get done riding a long trip, the heat that is put out to the touch is so much less.  The shifter shifts smoother.

The bottom line is regardless of how much extra crap the K & N allows into the engine, it makes no difference as these engines are bullet proof and if properly maintained, the filter may reduce engine life slightly but you could change the oil on these bikes with vegetable oil and they would still keep going and going.  They are equivalent to older Hondas or Toyotas, all of which I know stupid kids that have put vegetable oil in them for years with no problem.

Also, why do all these rice burners have fancy mufflers, intakes and god knows what else and I know many of them with over 200k with no problems.

Do what you want to the Savage within reason and it will keep going.  

Also, it is definitely true that 10 bikes from the same factory broken in the same way and identical in every way, will have slight differences and also a couple will be faster and more efficient.  I think I lucked out and got the freak fast one of the bunch.

Thanks

All this about Air Filters & no one pointed out OldFellers mod? That aint right.. They coulda saved the $$$ & had all the performance gains.
