EX-XX and boOZZIE, the dimensions of the shipping package for one set of headers will be 95cm x 60cm  x 45cm [or slightly less] and will weigh 7kg [or slightly less]. 7kg includes 1kg of protective packing material and the box.

Thanks for being willing to check out shipping to Australia!

Hi EX-XX  - sorry to hear about the $AUD tipping downward. I'll PM you and let's set something up to preserve your valuation.

HighSideNZ informed that NZ Post has a 'drop point' [for lack of a better term] in Portland Oregon USA, where private US shippers can have parcels sent. Then the NZ Post relays the packages through customs and on to New Zealand at reasonable cost. Perhaps there is a similar Australian service available for us small independent shippers and receivers?

Thanks for considering it Seb. I'll PM you in case it works out to purchase your Remus mufflers or use them for testing and fit a new set of headers to them for your 6th gen. Here's a thought - Wade suggested that one way to properly match the large outlet of the new performance header would be for him to fabricate midpipes.

Remus sounds great in two ways [1] just the sound of the VFR V4 running through them [2] as an outlet for our test 6th gen's burned gases.

I hope you noticed that we corrected our grave error of leaving you off our initial 'grateful thanks' list...you're first on the list now!

Duc2V4 and I are looking for a set of used 6th gen performance slip-on midpipe/mufflers to purchase, borrow, or have donated for use dyno test/tuning the prototype new VFR800 performance header. Our test 6th gen has gutted OEM mid pipe/mufflers, and those won't flow enough exhaust gas to take best advantage of the new header.

A cosmetically damaged 6th gen slip-on would be great if fully functional. Any brand or model that is open flowing is fine; Two Brother Racing, Delkevic, Micron, Leo Vince, Akrapovic, Scorpion, Staintune, etc

We would prefer to accept a generous donation or loan and will pick up in southern California or pay for shipping [pay shipping both ways if the slipon is a loan], but we are willing to purchase.

WE ARE NOT PICKY. Thanks for considering this.

Cool - thanks Voided76. PM sent.

In for 5th gen full system. What's the muffler gonna be? I like the sound of my Delkevic 8" slip-on, so I'd like something similar with minimal baffling.

Hi Airisom - thanks for your interest! As Note h in the OP vaguely states, we have not pinned down the 5th gen full system specs or pricing beyond "It can be high or low mount, and the muffler canister can be metal or carbon". Sorry. We're doing our best not to tip the boat with any variables until we have the prototype in our hands, but we'll get on the 8th gen header, 5th gen full system, and, if at all possible, a 6th gen full system once the prototype testing is done and the first production run is under way. [ps on the QT, I'm leaning toward a full system for my 5th gen and once we get to that point, will attempt to nudge the design toward spring tension fittings between the header and the midpipe]

PM for info on making a deposit or to be added to the B list, which is the' interested but not quite ready to make a deposit' group. Include answers to the informal survey so we can keep our thumbs on the pulse of the project.

Voided 76, Stray, and HighSideNZ - we are getting a lot of responses from 8th gen owners, which is very cool! I'll add you three to the list I'm about to start; the B-list [no offense intended if you end up on the B-list] which will consist of people who are interested in purchasing a header, but would prefer to wait before placing a deposit.

Check out my response to Samuelx 3 or 4 posts up from this one - it includes information about developing this header for the 8th gen.

HighSideNZ - I'm sure shipping to NZ can be arranged. Maybe you could PM with some coaching on the best way to accomplish this?

1) Re: Note c - can we have Wade perform the expansion of our midpipe connector for an additional fee? (applies to local members only I'd imagine)

1a) Re: Note c-  Possible to pay extra to have the 49mm midpipe connection as modifying a Staintune may be out of the question for me.

Hi Tanner

1 - on Note c, yes, purchasers of headers can send or bring their midpipe/slipon to Wade’s shop to have it expanded. Expansion is literally a 5 minute task with the right tool - a hydraulic pipe expander. I’ve watched Wade do it. It will be much more cost and time efficient to stop by a quality local exhaust shop that has a hydraulic expansion machine and hire them to expand a midpipe as described in OP.

1a - the tough answer is that no changes will be made to the specifications of units in the first production run. It will help if all of us, as a single community, think of our group as being in a position to respect the fabricator’s process and continue to earn his trust as we simultaneously motivate him to take on a second production run of VFR headers. There may be a possibility of opting for a 49mm exit pipe in later production runs, but probably not.

The pleasant answer is that like you, I have a Staintune slipon and will be having its clamp end expanded to fit the new headers. I will report back to you as soon as my pipe has been modified. For expanding mine, I plan to use a known auto muffler shop within 2 miles of my home that has done automobile catalytic converter work for me, friends, and family members.

Thanks for the heads up!

 

Where in So Cal - is there a reason why the name of the shop is not listed/mentioned?  I'm assuming it's in Orange or San Diego county?

Re: Note a - Can an 8th gen order be included in the initial group order or does he require an additional 15 orders solely for 8th gens? 

Do the two O2 sensor locations from the 6th gen also work properly for the 8th gen?

Also just curious, will the exhaust system differ based upon what kind of fuel management, what kind of muffler, or whether or not dyno tuning will be performed?

 

Good questions, Samuel.

1 - we have chosen not to list the fabricator’s website or exact location because, in the past, several potential manufacturers and distributors of headers have been driven away when multiple enthusiastic VFR owners - with only the best of intentions - went around the member already in contact with the supplier, directly calling and emailing the supplier into a frustrated state of disinterest.

2 - on Note a, we have discussed with Wade  the differences between 5th/6th gen headers and those for 8th gen. Because the headers will be constructed on an assembly line in jigs/fixtures that facilitate a specific confguration, production runs of 15 units will happen for one configuration at a time. Part of producing the 8th gen header will probably be making the front primaries modular so that a rear primary/collector assembly can be designed to fit all three gens - 5th/6th gen or 8th gen front primaries can then be selected depending on which gen the customer has requested headers for. Getting Wade to buy in to the viability of this project was tough. The more we demonstrated a fully developed objective with no complicating variables, the more willing he became to participate. As a result,  distilling the first production run to a single configuration that matched the sample TBR we had on hand was mandatory.

3 - nope, each 5th/6th gen header will be exactly the same. Detailed specs are listed in the original post.

Here are a couple of shots of the complete bike. Left and right.

HighsideNZ, I just stumbled across this thread and must echo the other compliments on your craftsmanship and documentation. Thank you for posting your machining spec drawings.

And to paraphrase Crocodile Dundee...

That's not an 8-spoke:

That's an 8-spoke:

braga2, I went with Jamie's recommendations for springs and valving. I told him my weight and that I put 85% emphasis on track/hard sport riding and 15% emphasis on loaded touring. He used his extensive experience to rebuild my Penske shock and CBR600F4i forks to these specifications. Couldn't be happier - 18 days on the track last year and just finished a 4257 mile trip w full luggage on the same bike, same DMr suspension. [DMr = Daugherty Motorsports]

Thanks VFRDiscussion

I'd like to chime in on pulsing brakes and uneven transfer of pad material as a cause.

Preamble:

I did a delink with 5/8" front master cylinder and RC51 SP2 calipers [32mm/30mm pistons] on my 5th gen. These brakes were operating smoothly, running Galfer street/track pads with 80% pad left. Then I rode member RVFR's 5th gen. His full CBR600F4i front brake system [5/8" master cylinder and F4i calipers with 32mm/34mm pistons] running OEM pads STOPPED LIKE WOW with full control, great modulation.

The actions I took:

[1] Installed OEM pads in my SP2 front calipers. I carefully scuffed the existing stock rotors with emery paper, starting with coarse, then medium, then fine, to remove material the Galfer pads had deposited on the rotors' surface. Cleaned the rotors with brake cleaning fluid until rag came away clean.

[1A] Noted that the brakes with new OEM pads were working normally on surface streets and freeway on the way out to the country road where I would bed the pads.

[2] Bedded the pads in to transfer pad material from the new OEM pads to the just-scuffed rotors. All brake applications were made smoothly, starting with light lever pressure then increasing quickly to high lever pressure, then releasing steadily, never 'snapping' the lever pressure off.  Made 6 hard decelerations from 70mph to 30mph, with no cooling time between brake applications and never slowing to less than 25mph [Never coming to a complete stop].

[3] After the 6 decelerations from 70mph to 30mph, was careful not to come to complete stop and rode with no brakes for several minutes to allow full cooling of the brake components.

The result:

Front brakes pulsed intensely from high speeds [80-100mph] or mid speeds [50-70mph] all the way down to 20mph or less before they smoothed out. Even at 20-30mph, strong application of the brakes caused pulsing.

Hypothesis:

I believe I started too hard on the bedding in process; I probably should have done 4-6 decelerations from 40mph to 20 mph with modest lever pressure before moving on to repeated heavy braking from higher speeds. In the bedding process I applied too much brake force too suddenly and deposited pad material unevenly.

Attempted solution:

I went back to the emery paper and scuffed the rotors again, doing three rounds on each side of each rotor with coarse, medium, then fine emery paper. The pulsing smoothed out somewhat, and now, 1200 miles later, has smoothed further, but is not gone.

Research indicates uneven deposits of pad material may be a major cause of pulsing brakes:

https://forums.bmwmoa.org/showthread.php?21352-Not-warped-discs-but-pulsating-brakes!

Post #16 here has some pointers:

https://www.pnwriders.com/threads/cure-for-pulsing-brakes.194058/

Next steps:

[1] Definitely purchase dial indicator and check rotors for warping/runout

[2] Possibly have rotors bead blasted.

[3] Possibly send rotors to truedisk [truedisk.net] to have them ground flat.

[4] Possibly install new OEM pads after bead blasting or flat grinding.

Ooooh. That explains all the other badass Hondas in the background.

Now that is pure endurance sex. How does someone come to have two Lucky Strike endurance RC45s?

Can anyone point me to vfrd gallery photos of a black three-spoke front wheels on a VFR? [Wheels from 900RR, 929RR, 954RR, 600RR, 1000RR, etc] 

Thanks - I just received an email response from Jamie. He has great input as expected. 

Jamie, one question to help refine the approach to your spring recommendations.

Question- are your rider weights for full rider with gear weight or do they reference dripping naked rider only weight?

Jamie, thanks for reposting this table. I was reading through this thread to see if anyone had quoted these spring recommendations from the 'transformed wow' thread. You provide a solid starting point for spring rate.
