I know people have posted about this, but im sick of running through hundreds of pages...

anyone installed the K&N as there FIRST mod.  i want to know if you noticed a gain in power.. good amount or a very slight amount...

Did mine same time as I did my exhaust sorry.

That was my first mod/ my 05 GS500F seemed to accelerate and run better after that / shortly after that I rejetted and with tha 2 I could tell a big difference in acceleration and top end/

Ok, I am also a newb... what the heck is a lunchbox while we are on this subject?  And when people are putting a K&N on thier bike is it just a drop in replacement filter or are they intake systems similar to the ones on cars???

ok there are 3 main styles of filters.
1 the drop in type, you use the original air box, and all you do is drop in the new filter. this only requires minor rejetting.
2 the lunch box type, you get rid of your air box, and its a single filter that covers both carbs, generly recognised as the best type of filter, requires major rejetting.
3 the pod type filters, again get rid of the air box, they are individual filters for each carburator. again requires major rejetting.
hope that helps, to clarify when i say major rejetting i mean you have to go to much larger jets than standard, its not any more work than a minor rejet

alright, this should be posted in the FAQ forum, b/c that was a good clean answer...... thanks man!

With a lunchbox filter and a rejet you'll notice a difference, not a huge difference, but a difference worth the cost of the filter and the rejet. 

Also with the lunchbox you get a nice intake sound that makes it even more worth it.  With low-revs and partial throttle it sounds about the same as stock, but when you open it up and wind out it's nice a loud, and as we all know loud is key to going fast.

That cleared it up pretty good!  Thanks for the answer Hmmmnz!

Wait a minute, I thought you didn't have to rejet with the 'drop-in' filter.
I need to verify this before I buy, because I don't want to rejet.

You have to keep the restrictor on the filter if you don't want to rejet. 

And the restrictor comes with the K&N filter right??

Supposedly, but mine didn't have one.

how much is ur average rejet??

cost me ~$30 shipped from www.sudco.com to rejet my '05

i put a K&N drop in filter in my bike the other day and i think it has more power. b4 it would get to 100 like it was nothing then it would be abit harder after that now it goes to 120 like its nothing then it gets abit harder. but the good thing about K&N filter is that there the last air filter you will ever buy

i bought it today, 60 bux, for the drop-in, they had one in stock, so i said hey why not, dont need to rejet then...  now, how do youy get to the fctory filter, i dont have the manual for my bike, i bought it used and it didnt have one......  fu&&ers...

i have never worked on a bike engine before, first time, car engines, ALL THE TIME...  help please...

you have the f modle yer?
1 take the seat off
2 rewove the 2 bolts that hold your tank on
3 now take your tank off and look under it there are 3 hoses you have to remove you will see 2 next to each other there is a small tap
   on the bottom of your tank turn it off
4 remove the hoses
5 remove the tank place it down it a way so the bits that the hoses go on dont get damaged
6 you will now see the air box remove the STOCK filter
7 place in the new K&N filter remember to stick the gasket that comes with the filter on the filter and put the filter in the right way
8 put your bike back together

and remember to turn that little bloody tape on i forgot to i had to redo all that at a servo
