Well, Seems ive found an answer for anyone else who is curious. It is a rectifier as per this parts catalog https://www.bike-parts-honda.com/honda-motorcycle/800-MOTO/VFR/2009/VFR800A9_A/Frame/--FAISCEAU-DES-FILS-VFR800A-/97198/F_32_1/2/10418 part number 4

diagnostics seems possible, there are about 5 wires going to this connector. what I find weird is the cap is completely taped to the harness. you would think as a diagnostics port it would be easily accessible similar to the red one on the right side of the bike. Browsing some images on google, i haven't seen any other harnesses with this connector.

Has anyone seen, or know what this randomly capped off plug is that is taped to the connector for the instrument cluster? I haven't found a wiring diagram that lists what it is

There are a ton of great options, but sound will vary significantly. I currently have LeoVince on my bike with the decibel reducers removed. its not ridiculously loud, and has a really solid deep throaty growl. With the decibel reducers installed its significantly quieter, but it looses that deep growl and starts to sound like someone is blowing hard through a straw. With out the Db killers i can cruise comfortably on the highway without hearing a significant amount of exhaust noise. I have heard the scorpion exhaust and sounds very similar to the LeoVince - they also have the ability to remove the decibel reducers. Two Brothers is another option, but keep in mind here that the left hand side muffler is a dummy, and exhaust only passes through the muffler on the right. I'm personally not a fan of this set up. but some people prefer the sound of the single exhaust over the twin. Basically, any exhaust that comes with a removable baffle or decibel killer will be a viable option for you.

Interesting. So that means its quite possible to work. Does he have any images on the form?

I've seen a member swap out an 8th gen hub and rim onto a 6th gen (which looked really solid, but has anyone seen or done a full swingarm swap from an 8th gen to a 6th gen?

That is a very interesting modification. I would really be interested in seeing how it looks all lit up. Curious to see if you would need a new relay or special resistors to maintaining the signal flash rate. Kudos on getting it all packaged in there nicely!

Are you referring to that slight popping noise that you can hear coming from under the tank? If so, tha's actually the pair valve opening and closing

The only benefit removing the snorkel has is you hear more of the induction noise. But agreed, it makes no difference in performance, however, I did notice with the PAIR mod, the bikes runs way more lean on the lower end of the RPM's and it ran much worse for me. The pair valve is N/O up until i believe 2k rpm where it abruptly shuts off. with the valve open, it creates a lean situation and the bike tries to compensate by adding more fuel. So blocking the valve makes the bike think its running rich and then it cuts back on the fuel which is why there is that drop in RPM when it is blocked off. I may be wrong on this, but i'm fairly sure this is the case. With the RB, I did disable the PAIR valve though and its so much smoother... I have done some more playing and modified the map quite a bit more.

After months of scouring the internet it became apparent that my VFR was plagued by a similar issue that many have that has no apparent cure. Lumpy idling, stumbling upon acceleration and over all poor running. I did all of the Troubleshooting that's in the repair manual and all checked within spec. Even checking the balance of the starter valves - all was within spec. I have tried various combinations of he PAIR mod as well with very little success. There was a lot of recommendation to use a PowerCommander but there was generally a divide where it either exacerbated the problems or only mildly made them better. In my research I came across the RapidBike Racing and Evo modules. What piqued my interest with this module over the PowerCommander was this module utilizes the O2 sensors and has the ability to adjust the fueling in the lower spectrum of the RPM which cant be modified by simpler modules such as the PowerCommander. The biggest downside was the hefty price tag. a few more hundred over the PowerCommander. But the results reported by all seemed promising so I bit the bullet and ordered myself one. Well, it took nearly 2 months to receive which was incredibly disappointing especially specifically ordering directly through RapidBike Canada. None the less, I spent last week installing this module. I was't particularly pleased with trying to stuff this module under the seat (where we all know there is no space already) so i decided to make this installation as unobtrusive and inconspicuous as possible. Check out the photos. Its been about 400Km since I have installed the module and holy $H!T, I cannot express the difference this bike has in performance, smoothness, rideability and overall engine characteristics. The increase in low end torque is unreal! I have played around with a couple of the MAP settings in the module and its only getting better and better as the module self programs Km by Km. So for anyone who is suffering from a similar plague, I highly recommend the RapidBike Module.
