First Performance Mods

So tonight I will do my first performance mods. They are:

Why start here? Increasing air intake is the number one place to increase performance on a motorcycle like the FZ1 with no RAM air intake. It works well for a tight budget too. :tup: Other than my time this upgrade will cost me $100. $70 for the Italian made BMC filter and $30 for the sub-throttle plates.

I chose BMC simply because it was recommended to me by some of the track day racers at my local Houston forum. They like BMC filter because it has a much more rigid frame than other filters like K&N which usually have some type of rubber frame. Why does that matter? The rubber framed air filters allow the entire body of the filter to flex when it starts sucking in air. I want air to flow immediately not have my filter get sucked in and out like an accordian. Any truth to that? I do not know but I trust my racing buddies. :)

Unfortunately, my feedback on this will be purely subjective as I have never dynoed my bike and do not plan to before and after this upgrade.

Copper Dawg's video pretty much covers everything that needs to be done and better than I ever could. If I come accross anything not shown in the videos I will take photos and post up.

Are you running a powercomander or some way of adjusting your fuel to match the increased air flow ?

Not at all. I will definitely do this when I get in to more expensive mods like exhaust. Power Commander is on my X-Mas wish list. If I end up getting any kind of bonus this year I will get an exhaust and get everything tuned in.

If it sucks without the PC I will definitely let you all know. I have made similar modifications on previous bikes without a Power Commander and without any issues.

I would definitely like to hear everyone's thoughts though.

Well sounds like you thought this out well. I will add that while you're increasing air intake you're not doing anything on the exhaust side, which is a real bottleneck on these bikes. You will not believe the performance increase that you're going to get when you do your exhaust...and a full exhaust is definitely worth it.

One thing that I will add is that I saw somewhere else where someone compared the BMC and K&N filters and the BMC's filtering media had a bigger surface area. That's what I have in my bike as well...

Let us know how your first round of mods turn out.
 
I have some concern you may run too lean with a modded airbox and without a power commander.

I have an 08 and first mods were to get new can, and gut front cat and change to lower 16th front sprocket.
Then I opened the airbox and descreened the stock filter , and while the performance is great, the bike is running lean and my pipes blued a bit.

I am for sure putting a power commander on this off season as well as copperdog flies.

the only mod after that for engine with be an ignition module, but that can wait

I don't think his bike will run lean just doing the intake mods. You ran into the issue because you had also done the exhaust mods.
 
On the intake side and for the money it sounds like you are right on track. Just remember that there is an old rule that says if you stuff more in, you must also get more out. One side of the equation alone rarely get's more power. It takes full breathing at both ends to make much more power and torque than Yamaha already has in the stock machine. When you do get it breathing better you'll need some type of fuel metering alternative to get more juice going through those improved throttle bodies. I would guess from my own personal experience that $100/additional horse power is pretty close to what you can expect from a cost perspective. Good luck with your project and keep an eye on your plug color, it will tell you a lot a lot about your mixture.

I need some exlax for motorcycle exhaust. :eek5:

Hopefully it will not be but a few months before I do all mods. Just got a bite on someone wanting to buy my boat! :tup:
 
Ok, here are a few shots of the air box. Inside view, bottom view and one shot with the bits going in the trash. I am going to take a bit of coarse sand paper to this to smooth out the rough edges before re-installing.

After the snorkle is cut out:

As seen from the bottom. I later sanded this down much smoother with 600 grit.

If you have seen copper dawgs video of installing the sub throttle plates you know it is pretty damn good. Two things. 1st There is another hose that connects to the bottom of the air box that you must disconnect that he does not mention in that video. I think it is part of the AIS (sp?) that others have been talking about. 2nd it took a lot more heat than the 2 seconds he placed his torch on those screws. I did had to do about 10 seconds each and they came out easily.

You can actually still open up the airbox a lot more. Cut all the way to the vertical edges on that inside view (1st picture). Look here to see what I mean:

Dang it! :)

I actually cut away about another 1/4" around after the photo. I debated opening it all the way up and decided to wait for now. I became a bit paranoid after a few responses to my post. I will open it all the way up when I get a Power Commander and exhaust.

Here are photos of the throttle boddies before and after the new ones were installed. Also a photo of the purdy BMC filter as I was closing her up.

Did you mod your own throttle plates? Are those the graves VS? Also, did you have your tank on when you took that? I had some difficulties getting a good shot with my tank on. Maybe it is my POS camera.

Those are Ivan's sub-throttle plates and yes those are the Graves VS. Not sure how much of a difference they make, but I got them really cheap so decided to throw them on there. I had my tank off when I took this picture. Matter of fact whenever I do any work that involves the airbox I just remove the tank and put it aside. Makes it much easier to work IMHO.
 
Now for my qualitative feedback....

Love the throatier growl! Definitely pulls a bit harder in mid range (5,000 - 7,000).

Next will be my motorcycle exlax project to let things flow a little easier at the rear. I am considering either Yosh or Akro street legal slip ons and Power Commander (with O2 sensor).

Well for the price of an Akra slip-on you can probably get a full Yosh exhaust. I went with the R-77 in CF for my bike, but if you stick with the SS version you can pick it up for less than $600. The full exhaust will save you the hassle of gutting the cat in the stock header and will fill in the midrange of the powerband.

I didn't realize there was such a price difference. Is there any way to retain the center stand if you put on the full exhaust? When I am Camping it comes in too handy to give up. I did without for too long and now I am spoiled.
