My Brand New 07 VFR800 RWB

Hello everyone. I just traded my Ninja 650r for a brand new 07 VFR800 RWB. Wow what a difference. So far I love the VFR. It's just so comfortable and smooth especially at highway speeds. I did notice the flat spot right before the Vtec kicks in and was wondering if any of you have added a power commander with the stock setup with good results. I really want to keep the bike stock but would like to smooth out this issue. Thanks for your help.

 

welcome and congrats on the bike

there are plenty of guys that will give you good answers...

a power commander may do the trick

I would suggest a few cheaper options to see if it helps though, both of which are fully reversible

1) "air box mod", which lets her get all the air she wants at all power/speeds

and

2) PAIR valve removal or disabled

All kinds of good threads on these. I removed the PAIR valve completely on my 07 and she just feels better all the way through.
(The PAIR is a system that steals a little bit of intake air and routes it to the exhaust - emissions thing)

Good luck, and nice bike!

 

Welcome. I came from a 650r to the VFR myself. I must admit I don't miss the buzz in my entire body after being on the 650r for an hour. I liked my 650r but I LOVE the VFR. For me it's the perfect bike and I hope you enjoy yours as much as I.

 

Yes, definitely a much smoother engine. I just got back back from a 30 mile jaunt around the city and it made me smile. I just hope I'm not being to hard on it as it is still in the break in period. The mechanic where I bought her said as long as I vary my rpm's while riding it will be fine.

 

Nice ride Rob, and :welcome:. Yes, the consensus round here is that adding a PC3 and doing whatever o2 sensor elimnation you choose will eliminate the flat spot before VTEC engagement, with or without stock setup of air filter, exhaust, etc. There are a couple "standard" maps for the PC3 floating around but the best seems to be to just nut up and get her dyno tuned by a pro. I wanna do this to my girl to eliminate the jumpy surgy feel at the lower end as well as the dip just before VTEC.

 

Welcome to the madness.

 

Put some good miles on that engine before you start trying to tweak out the "flat spot". The whole VTEC thing ages for the better just like a good bottle.

 

VFRob:

1. Congratulations and welcome to the World! I bet and hope that your enjoyment of the bike will only grow with time.

2. I also endorse Jason S.'s comments about waiting a while. When I got my red '07 last year I was very concious of the flat spot or actual slight torque drop-off right below where the VTEC kicks in. One year and 2,500 miles later it seems to have improved markedly. I don't understand why this should be so; the fuel injection schedule and cam characteristics don't change with break-in miles. It may be just me getting used to it but I'd love to put my bike on a dyno 'cause I sure don't sense it anymore. Different riders have different sensibilities, and individual bikes probably have their own variabilities; if it still bugs you after a couple of thousand miles you can always try the mods then.

Ride safe, have fun.

 

I went the PC3 route. Loooove it

 

Congrats on the new ride, VFRob. I picked up a new RWB VFR last Sept. and after 6k miles, I agree with the other comments things smooth out with miles. Enjoy the new bike!

 

I did the $.98 cent Radio Shack O2 eliminator, and it helped both the very low speed throttle sensitivity (chugging) and the VTEC; for $.98 cents, literally.
