Will Mods put a smile back on my face,

Hi there, new to the forum. Purchased a 06 VFR last year, black. I have put a few mods on them but mostly cosmetic. First, I love the VFR, the fit, the handling, just an easy bike to ride and it looks sweet. But I am not impressed with its power. I know there are many post talking about this mod, that mode, but here is my question.

1. If a put on Stain Tunes, gut the cat or replace them with 99 headers, PCIII USB, and KN air filter, will this really make a significant difference? We will I get more power from the bottom, will I see more mid range power and pull. It just does not feel like an 800 CC bike.

Thanks all

Sounds like you looking for a big twin alot more low end torque than an inline or v-4. zx 10 has a little more midrang kick but not much more but right around 6-8000rpm would leave vfr in the dust.
k1200s might be the bike for you , so many great comments about them would love to take one for a spin. ducati st has a lot more low end torque as well.
the only thing staintunes did is make the bike sound awsome your not going to get any more noticable hp out her with that mod alone from what I have noticed, but then i never gutted the cat or added a pclll.

Good luck

 

You could try changing the gearing. Simple mod, some say one of the best.

 

I agree with Reg .
I am also a power junkie , and find Myself Drilling the Viffer for it's 7-10 000 rpm surge. Strictly though , mot recommended . As a mid-distance cruiser she's One of The best . as a short range missile , a bit too bulky .

a Damn 600 wil give you a thrashing from the blocks all the way to the Pub man .
so as a victim of power - I'd agree with you and say that doin all the mods you have listed will probably NOT Impress you . Sadly , I am also Of the opinion that this engine should Surely Be capable of More ?, in a more stream-lined " set-up than what one finds on the VFR ?? I just Love the sound of that motor running low down .... gurgle gurgle . Yum .

Thats why we Love the Bike so much !

 

I did the cat gutting, staintunes and PCIII - if you do a search under my posts you'll see a dyno chart. The power gain isn't big, but driveability is a lot better.

It knocks seconds off at the track, but it probably won't help you drag against a ducati 1098 with 140 hp.

Take a look at the dyno sheets,

well said reg71!

 

There is that turbo kit that I saw for sale once...

 

that would be bad @$$:biggrin:


i got the VFR after having a F4I, and i noticed a power difference. i have to downshift more on this bike than i did before. i recently added a PC3, -1 front tooth, and am gonna be gutting my mufflers soon. i like this bike, but if anything happened to it id probably get a 1000RR

 

Maybe I just don't get it. My '02 has all the power I need to maintain a HIGHLY AMUSED state while riding it. The V4 ROCKS!!!

If I was unhappy with the VFR's grunt, I would sell it and get a literbike.

I said it joking, but if you really wanted it, there is a company making it.
What is the place in Canada, something like Dynohum? they sell it, or at least used to. If I knew how to spell it, I could check.

 

Go down one tooth on your front sprocket.

 

1. Cut the end caps off the mufflers.

2. Rip all the junk out of the muffler leaving nothing other than the SS shell.

3. Have the end caps welded back on.

I've actually seen this mod on a 6th Gen & I swear it sounded like TWO Ducati's rolling side by side. It will make the hair on your neck stand up & aside from the cost of welding the end caps back on, it FREE.

KC-10 FE out...

im gonna be doing this this weekend hopefully. i have a friend will all the stuff ill need, and then i can add some fuel with my PC3 so it wont run lean

 

Your mufflers have zero effect on running lean. A modern FI'd bike is not going to run lean unless tuned to do so from the factory. Even if you messed with the cats, I doubt it would do anything. The mufflers? Not a chance.

I would have to agree, the best mod for the buck is a change in gearing. yes, gutting the cans will reduce the back pressure and free up a couple of horses. But a change in gearing will affect acceleration. I went +2 on the rear sprocket and I could tell a big diff over stock gearing. If I go -1 on the front, it makes a bigger improvement, but for my tastes, it brings the cruising rpm up to high for my comfort (65 mph is somewhere around 7 - 8K rpm if I remember right). With this mod, there is no change in HP numbers, but it makes what you have more useable at different rpms over stock gearing. Also, if you do change the gearing, I advise investing in a speedo healer to correct for the new speedo error.

 

I hear that if you drill small holes into the end caps of the muffler you gain a heavier exhaust sound. i never tried it. But also keep in mind that modifying the exhaust system is actually illegal... so if you do this mod you should make sure you do it evenly and symmetrically so it looks factory.

If you try this, please post your results.

 

Hey BidD,
Did you happen to go on the flood run? I live in Buffalo MN. I went for the first time and there were a ton of bikes, was pretty cool.

 

Must say I also Went On my First big run 'yesterday , and it was pretty damn Cool , with Only 2 of us having Vfr's . What they did teach me yesterday , is that one does not need to ride like an ape on this bike to be able to enjoy it .

70 Mph was max speed , and we all rode in a convoy - 230 Bikes .
Very impressive , and very enjoyable .

 

k1200s vs 06 VFR

The VFR is a great bike, but I sold it and got a k1200. Having owned both bikes here are my thoughts on the differences.

First, there are not the same bike: totally different in power, handling breaking suspension and other conformts.

Advantages
1. The power on the K is just one word! Incredible
2. The fit, I am 6 1, fits me little better
3. The ease of use wit the ESA really adds well
Simply, it is an incredible machine to ride

Downfalls.
Clunky transmission
Two - Slightly heaver, and unless you are an expert riders unlike me, I found the K to handle in the tight twisters less better – more work – but that could be my riding expeiriance
The transmission on the VFR was far smoother
The VFR is IMHO was slightly easier to ride in traffic
And my only complaint is the 800CC engine. They should put a 1200c on the frame.

Advantages
Excellent power delivery in any gear, any RPM
Easier on long rides with the suspension - but the Seat SUCKS!!!!
Bike feels heavier and for some reason I feel slightly more confidant on the K then I did the VFR, especially in cross winds, K holds the ground better, but that is not to say that a good 35 cross wind wont wake you up.

VFR IS MUCH MORE AGILE!! Period It takes more work on the twisters on the K than on the VFR, but when the turn go straight it will be only a few seconds before I would be blowing buy..

I would say the VFR is entry level sport bike, a stepping stone to a real machine. And I love VFR. I have owned 4 of them, but what has disappointed me as a loyal VFR fan, is I feel some of the other bike makers have really out done Honda in terms of technologies employed and power delivery. I am seeing more ladies buy them so that is perhaps a reason they keep selling.

Any my two cents. Buying a 02 VFR net week just to have one around and take smaller in town trips on.
