Got a hair up my ass today and decided to figure out a K&N filter mod. I like how it looks, but with drilling out my pipe baffles and the increased air intake, she is pretty lean now. I should have my Cobra Fi2000 tomorrow and hopefully that will fix the lean situation. Can anyone guess what they are? Big ass crankcase filters that fit right into the stock air intake hoses. Gimme some honest feedback, thanks guys.

It would look better if you figure out a way to center them between the jugs, but I give an A for functionality.  :D

I meant to ask, did you drill out pipes and do the breathers at the same time. Just wondering in relationship to the lean condition, if it progressively worsened with each mod or not.

Yeah I did them both at the same time. An yes it would also look really good centered between the "JUGS"....gotta love the jugs!! :evil: This bike really needs a Fi2000 or a Power Commander to get the fuel mixtures right with the usual mods we will all likely make.

i like the pipes that bend forward into a cone shaped air filter.

Honestly, they look too small. This bike is about big and bad. Those look small and wimpy!



You asked for honest.

Yeah they do look smallish, but in person they look better. I could not find the tapered cone filters that I wanted, but in the meantime these will do. I am more interested in performance than looks any. The air intake has improved, thus improving performance which is what I want. The bike sounds even meaner with the pipes drilled out and screams when you get on it. When I get the lean problem fixed it should sound better. I used a drill bit extender and a twelve inch bit to get to all of the baffles, three in all. I appreciate the honestyn and we all like what we like. Thanks.

Maybe you could start a thread about drilling out the baffles with some pics. I am interested in seeing what you did. I was thinking about just punching out the baffles if that was possible. Old HD trick using piece of rebar and mallet.

I've been dealing with Ivan at Ivan's Performance Products for a few years. He makes very popular jet kits for the ZRX and FZ1, as well as FI and other related performance mods for modern sportbikes. He is a genius when it comes to Intake performance. I will call him about the 109, but I am going bet that he will say that the airbox design in modern high performance bikes plays a huge roll in performance. And not just peak performance, but the engine characteristic. On some bikes, he even recommends using the stock filter for optimum performance. My point, don't assume old school hot-rodding tricks will benefit you on this bike. Remember, Suzuki is using "GSXR" technology in the FI system on this bike. Maybe he would be inclined to research the 109 as it will likely have a following in the sportbike community. I'll let you know what I find out if anything

I think if you can get those filters under the tank, i.t would look even better. I am also interested in the tone/volume difference/power from modifying the pipes.

I'll tell yall what. I just got done with the Fi2000 install and made a few runs. Man oh man it works great. So i've drilled out the baffles, added the K&N's, like you saw, and installed the fuel management module. I will make a new post outlining all of it with pics. But for now I am going riding.

I think it would be cool if we had a 109 rally some day after the aftermarket catches up and everyone has had a chance to do their mods. It would be nice to see and hear all the different variations. I think we can eventually post up pics and dyno charts, but seeing and hearing the bikes in person would seal the deal for so many people on what they really want and need. I would love to hear a bike start, idle, rev, leave from a stop, accelerate - then turn around and come by at redline!

That's what I am trying to do for Florida riders. Of course anyone else is invited but could be a long ride from others. ;)

Make it during Biketoberfest! Maybe we can get a good turn out.
