    I have an 02 and it idles @ like 1100 RPM, OK if you just barely roll back on the throttle it is like it is starving for gas or maybe timing? until you hit 2500 RPM and whoa she takes off.

    I have done the pair/flapper/fuel regulator/evap can/ and smog electronics disconnect and O2 eliminators mod's. Using a 99 catless exhaust did it w/ original exhaust as well...

    Any ideas??

    PS/ I don't have a PCV yet. $$$ :frown:

    This poor bike had several owners b4 me so who knows what has gone on. I do know that they lowered it, gutted stock exhaust and made a make shift fender eliminator so who knows what else. :tongue:

    I thought the 6th Gen's idle was supposed to be closer to 1400? Either way, 1100 sounds too low. I'd at least bump that up.

    My guess is with all the changes you've made
    and no PC, you've sent your stock system in a continuous hunt for the proper A/F mixture. All the stuff you removed is supposed to be on there when using the stock computer. ONly my guess, but I think a PC will help cure what ales you.

    Obviously you're only transiting those revs normal riding should be above 4k as a rule on a VFR. Having said that have you had the CVs balanced ? Mines done every 12 month service and find it gives a crispness to the revs just off idle especialy noticable in very slow dense traffic.

    Other that that you may need a PCV, my gen 6 I had in '04 before my gen 5 would sometimes suffer when cruising in the country where you roll off the throttle to coast down to the towns speed limit then feel dead before jerking when rolling back on the throttle.

    UK BIKE magazine at the time did an article centered around the poor fueling of the then new injected FZ1 but mentioned others including the VFR where to help meet pollution standards the bikes injection would lean out on cruise then shut off completely when rollng off the throttle causing the plenum to dry out. When you rolled back on the plenum would need to be wetted first causing a brief delay which caused the rider to think nothing was happening then overcompensate. Once understood I could ride around it but a PCV in the end was the only solution in the Bike mag article.

    Just got back from a ride and tried it...not really noticeable like before hmm just a cold motor?

    This bitch run's like a banshee, no hesitation around 4500 anymore. She just wants to get it :cool:

    Still have not removed the snorkel though with everything else doe might as well huh?

    Got a cheap chinese filter in for now *temporary* would like to get Pipercross any feedback on them?

    She also runs pretty cool too around 178F. I feel that is pretty good for these bikes it is 80F outside a lil warm but nice indeed.


    PS/ something that has been on my mind. I would like to apologize to EVERYONE for my language and disrespect that I showed to the forum community attacking BB the way I did. I am so sorry that is not me. Really I like to make people laugh and joke around and stuff so please forgive my ignorance and vulgar language that was displayed in my fit. It will NOT happen again...I am so over him. :crazy:

    The snorkel remove is a easy mod to try and sounds good but I re-installed mine after 2000 miles because I didn't like the way it made the lower to lower mid range feel fluffy.

    Speaking of my ride....It was a fairly short ride with HeliBArs and my throttle hand-index finger and thumb only was going numb any suggestions? Oh and my traps they always hurt. Should I pull the bars inward a bit? I have them mounted as high on the forks as possible even removing the snap-ring if you will. Granted it is not so bad around 75mph or so in town kills me the Zero Gravity DB made it worse at slower speed, but really nice at a ton + Chicky style :cool:

    Maybe should have left it alone?

    The engine and computer is tuned for the equipment the factory shipped it with. It ain't a 1968 two stroke, engineers got paid good money to make that machine run right to begin with.

    By low to low/mid range consider 4k to 5.5k. Below 4k is not recommended to cruise around in especially in 4, 5,6th but bear in mind the VFR has a 12k redline.

    Beat me to it pliskin

    And there's a difference between doing things right and doing it half ass even when tinkering. Doing your research, creating a baseline, and testing the results.

    You've changed how the engine breaths so get the power commander and a custom tune.

    The good news is since its your bike, you can do with it/to it whatever you want.

    You did come on and make a post about a hesitation and sputtering. You got some feedback about how maybe all of the mods you did (while not quite completing those mods due to the lack of a PC) is leading to said problems. But now that you got some answers, you don't really need our feedback 'cuz she run's like a bat outta hell? I guess I must be the :crazy:eek:ne now!

    Attention KMart Shoppers: Please stop posting about mods done to your bike because if I read about them and do it to my bike and she doesn't run right, its all your fault.

    Normally I'd agree you shouldn't need to monkey around with a well engineered motorcycle but Honda messed up the fueling of the early gen 6s.

    I've said it before but I was irrationality annoyed for a time how bad the fueling on my previous '03 was compared to the the good fueling the standard mk 1 injection is on my '99 gen 5 and non of those mods are particularly difficult so would think giving it a whirl worth trying and undone if it didn't work especially if posted with detail on an enthusiasts forum such as this one or VFD.

    IF you will open your eyes you will see way back in post #4 I stated she was running like a banshee...once warmed up.

    Stated as well in post #4 that the hesitation was not noticeable when fully warmed up.

    Your right. We did. For the life of me, I still can't figure out if she runs like a banshee or a bat outta hell. Please clarify, and we can put this one to bed.
