    Hello VFR800 enthusiasts. I am new to the VFR800 and want to mod/improve the bike. Are there any mods that significantly improve the bike. So, far everything I have done is purely aesthetic.

    Here are the mods I have done so far,
    ZG DB windshield, LED mirrors, chrome levers, fender eliminator, custom seat, fresh paint.

    Does a different exhaust system improve the performance or does it just change the sound. I like the look of the stock exhaust and would not want to change it unless it dramatically improves performance.

    I am considering getting all the aluminum brackets chromed.

    The whole bike is aluminum so there probably is not a way to make it lighter by a significant amount??

    From what I have read, everyone says that you only get a few HP with changing the exhaust. This is mostly due to the restrictive catalytic converter that is built into the header pipes and you can get a few more HP by replacing the headers, getting O2 eliminators, adding a PCIII, and tuning it. There are a few around here getting close to 110 RWHP if I am no mistaken.

    The popular mods around here seem to the be PAIR valve mod, Flapper mod, and airbox mod. Search them out in the mods section or the wiki. These dont add much power but it is supposed to smooth things out a bit. These are for performance only.

    Comfort wise, a lot of people tend to go with the Heli Bars, LSL Convertibars, or Genmar risers. It seems the Sargeant set is a tad more popular than the Corbin but everyone loves both, and some go with the VFR peg lowering blocks. Also, many choose to replace the grips, with a vast majority of us going with the Progrip 699's. I did and am very very pleased. Again, use the search function to track down anything specific you want to check out, tons of information on the forums.


    VERY IMPORTANT!!!!!!! Since you are new to the VFR800, check out the wiki for infomation on recalls that have to be done. There should be two or three that need to be completed on your bike concerning faulty wiring and the proportioning valve on the braking system. Call your dealership with your VIN to find out if recalls have been completed or not.

    An aftermarket exhaust combined with a Power Commander + fuel remapping will add a few extra horsepower but nothing significant. If you have a 6th Gen VFR you may also want to consider swapping the stock headers with some older 5th Gen catless headers and bypassing the O2 sensors. If you want better acceleration off the line the easiest way to achieve this is to change your sprockets. Either 1 tooth down on the front or 2 teeth up on the back will give you better low end acceleration but will also reduce your top end speed and increase RPM's at highways cruising speeds. In addition to this, your speedometer will also be thrown off a few more mph. If you are looking for stock exhaust looks with a nicer sound you may want to consider a partial or full gut of the exhaust which can be done in a few hours with some simple tools (drill, dremmel, vise grips, etc.) There are plenty of threads around with instructions on how to do it. If you have more money than you know what to do with you can consider a supercharger kit (@160hp) which will run you a cool $5000 or so. What year is this "alleged" VFR that you own? Without posting a pic or two of your baby we won't be fully convinced that said bike even exists :biggrin:

    Regards,
    Rollin

    It is a 2006. Here are some pics I took today. I did not think anyone would want to see pics of the bike that they already own.

    if you are trying to shed some weight go with a two bros carbon fiber vale(any aftermarket exhaust should be lighter but i believe the 2bros is the lightest). that should drop about 20 lbs off the bike. most importantly that weight is up very high in the bike and is very noticable... going with an aftermarket header will drop some weight too, but i wouldnt suggest it unless you are after every last horsepower and pound of weight. because, the weight is down really low and it is a mission and a half to install...

    It is not a performance mod, but I threw a Flash to Pass on the bike and it is worth it's weight in gold. I get home from work at 3 am usually and I am whipped....to be able to pull up to the garage and just drive in is awesome!

    Thanks, for everyone's suggestions, I will start with some smaller mods like grips, o2 eliminators and work my way up to tunning/exhaust. Thanks for taking the time to make detailed post.

    Has anyone ever done a headlight mod? I have some extra projectors and ballasts from a car mod I did last year. I think I need to get an extra pair of stock headlight to experiment putting the projector inside the headlight.

    Has anyone converted their headlights to HID/XENON that uses a projector lens. I would have to use a DR4 bulb which is much brighter than the H4 bulb. I know the H4 is dual intensity but I dont mind losing that feature. I could post some pics of the bulbs and Ballasts.

    The PAIR mod is quick , easy and well worth the effort, it smooths out the low end throttle response quite a bit.

    So here's a silly question; based on what I read on the wiki, if I do the Radioshak O2 fix, do I still need to do the PAIR mod? Seems to me like they both address the same issue?

    correct, the reason that most people do the pair mod is so it no longer interfears with the o2 sensors. but, if you simply do the o2 eliminators, there is nothing that is going to see the pair valves allowing extra oxygen into the exhaust.
    if you do the o2 eliminators the only reasons to do the pair valves as well, would be for the slight weight savings, a cleaner engine bay, and more acurate air/fuel ratios readings if you are having your bike tuned on a dyno...

    I thought the PAIR mod was just blocking the tube, how's that save weight?

    If you get the block off plate kit, you can remove both pair valve assemblies, block the remaining holes off and remove all corresponding hoses and etc...

    It may be worth about 5lbs, but you'll get rid of a whole rats nest worth of shit...

    So, today I did the Radio Shack $.99 (still!) O2 bypass, changed the oil (K&N Oil Filter & Repsol 10w-40), and cleaned & lubed (WD-40 to clean, PJ1 blue to lube) the chain (thanks for the instructions Mello Dude).

    What others on this site have said; the O2 bypass and synthetic bike oil have DRAMATICALLY improved my bike. It's like a new bike! The throttle response is INCREDIBLY more smooth now, no more sputtering and choking; and the VTEC transition seems smoother. I don't think it actually is, but there was some lag sometimes just before the VTEC kicked in, almost like turbo-lag, and that is gone, thus the transition seems smoother...

    The shifting of the transmission is much more positive now. I can hear the clicks every time, and there is real positive engagement; before sometimes I felt like I was fishing for a gear, not sure if it was in the right gear or not. It almost always was, it really wasn't bad; but, I wasn't sure, and now I am.

    I'd like to thank everyone at this forum for all their help and support; it is much appreciated. I have always enjoyed learning from others vs. trying to figure it all out on your own, and this site has made that easy.

    I have the same question, but more around safety: Better mirrors (I have some after market ones now that could be better) and big time lights... like flashing LED in back... maybe something more fancy in front than stock. The main reason? I never (ever) thought I'd ride my VFR as much as I do since moving from NH to CA. Now that I'm in the Bay Area... jesus do I need that bike. It can park anywhere and lane splitting is encouraged, so I'm going to be on it a lot and want to be seen.

    Any general thoughts on a smart path re: mirrors and better "lighting it up?"
