An old idea that Im looking into again.

FCR 41mm down draft carb set.

As we learned the last time this came up.. Kehin developed and produced the VTR setup exclusively for a Japanese company and could not provide them to any other dealer/
I have been working with SUDCO to discuss which of the available down draft FCR 41mm carbs might work for this application...
And was gifted the company name in Japan.

"Hello Erik,

We never had direct access to the VTR1000 FCR carburetor, Keihin produced them exclusively for the distributor in Japan called JB Power / Bito's R&D.|"
Located JB Power / Bito's R&D easy enough, and found that they are not currently listing the VTR as a supported bike model....
But have sent them a request for information in English and a Google translated version I hope is not a mess in hopes of eliciting a response from them...

I have also submitted a dealer application and was approved by Sudco, still waiting on Keihin but I have zero hope they will approve me as a dealer...
We shall see

They can still be had new (based on recent searches, though that could be on non-updated websites) and pop up (used) from time to time on the jauce.com site, but they are $$$$$$$$$$$$$$$$$$$$

I have always dreamed of having a set (with the airbox configuration)... oh well.....

JB Power / Bito's R&D was distributed through different dealers from what I saw (on various Japanese sites, including the Webike site, they have since been dropped from the latter). I recall seeing a place in the UK which listed them (Allen's Performance?). Mind you, it's been a while since I allowed myself to dream about these and go through the requisite Google search. Would love to give them a try but it seems quite unlikely for me at this point. Do keep us posted, however.

So they got back to..Im impressed, but disappointed..There was no "congratulations, I just tripped over a set up those in the break room being used to hold a door open...you can have them if you want?", .

What they did say was
Dear Mr. Marquez,



thank you very much for your inquiry especially for translation the message into Japanese.



It is true that Keihin made an FCR Carburetor for the VTR1000F which we have been selling, yet a few years ago Keihin decided to cancel this particular model.

However due to ongoing demand our company is currently evaluating to continue the production on our own.

We are kind of a big thing when it comes to special models like the VFR400R/RVF400, VFR750R, KZ1300, CBX1000, Benelli Sei and many others.

I will have a talk with the development department as well as Mr. Bito and come back to you with the current status.

And another response this morning
Dear Mr. Marquez,

I have had a talk with Mr. Bito and we believe we could ship in approximately 2-3 month, if you choose to order.

Furthermore I would like to mention our ultra light Titanium Exhaust systems.

Carburetor and exhaust combined provide an significant increase in flow.

The exhausts made from only 0.7 mm thick titanium our exhausts are lighter than any competitor we know of.

Looking forward to your reply.

Best regards,

Dirk Winter
Anyone have a few million Yen to drop on carbs???

well you better realllllly want a set...

They will come ready to set into the stock manifolds
Use the stock airbox
Use modified stock cables
And shipping will be free...

For the low, low price of .......Somewhere NORTH of 148,000 yen or $1,300 USD....

I'll let you read the rest for your self

Dear Mr. Marquez,
doing this in English is perfectly fine.
I have attached a photo of the version we used to sell.
This was an improved Keihin version which also works in combination with the original air cleaner box different to the Keihin one.
(The one photo has the special cleaner box air funnels attached, which were sold separately and are currently also out of production)
The original carburetor did fit onto the genuine insulator rubbers.
The original throttle wires could be used yet needed to be shortened and equipped with out special wire ends (sold separately).
Most likely the new version will be similar to this one with minor changes like different TPS sensor.
As for the shipping cost:
Here are the approximate shipping cost of one unit to business customers for each of the locations.

US: 15000 + Fuel Surcharge
UK: 20000 + Fuel Surcharge
Australlia: 15000 + Fuel Surcharge

In case of direct orders form private customers we are going to cover the shipping fees.

As for the carburetors cost:
This is a tough one it depends very much on how the final carburetors will look like,
the old one was about YEN 148000 list price which is rather unrealistic for the new one as we have significantly higher production cost.

Could you give me some insight about how many units you and your associates are talking in total, knowing this would be very beneficial for our decision making and planning.

Hopefully this information helpful, looking forward to your reply.

If our other VTR1000F parts are interesting I will provide you with additional information.

Especially wheels, pistons and exhaust are a great step forward.

Best regards,
Dirk Winter

As your English is clearly better than my Japanese, for which I apologize, I’ll do this in English.
Thank you for the fast response, and please pass on my thanks to Mr. Beto
Having never seen the carburetors as delivered by Keihin, or BITO R&D Co.,LTD. I am not sure how they are to be configured or what is included.
Are these bare carburetors with just the connecting side plates? Complete ready to install kits? Something else…. In other words what is included in the carburetor set you propose to supply?
What do you anticipate the cost will be for this carburetor set shipped to the US? Same question shipped to the UK, and Australia; those are the three locations others have expressed interest in these carburetors.



Respectfully;


Erik

It's one thing to covet FCR for a race bike which is WFO or off the gas with maybe a bit of trailing throttle, and quite another for street use. That is why starting in the mid to late 70's most street bikes came with CV carbs (+ EPA constraints). Now most FCR incorporate an accelerator pump but on-off transitions still often tend to create a lean condition. Availability of VT applications versus the much more common straight across 4 is the big issue.

Then there is Mikuni. See these "guys" https://www.mikunioz.com/shop/mikuni...v=7516fd43adaa

Granted there would be a lot more factors involved to complete the system, but for that kind of money FI seems a better option. Just thinking.

So a few things... the FCR series carb is a wonderful thing on much more then just a race bike..
Perhaps its something you just cant understand or appreciate unless you have ridden a street bike with properly tuned FCR carb (or carbs)
Ive been installing and tuning them on the Suzuki DRZ 400 bike since 2003 for both Sm use and dirt.. both of my personal DRZ's one a stroked bigbore 475cc in SM trim and a dirt only 434cc bike run an FCR... I have ridden pikes peak wining v twins bikes with them, and done some track time on in line 4's.using the FCR.

The throttle response is in a different range then the best tuned CV carb.
That said, no at the buy in cost I don't think I'll be doing it...as much as Id love to have the benefits for the Superhawk, the price is just not what I want to spend limited funds on. there is a DRo equipped low hour, powered on all axis, variable speed Bridgeport out there someplace waiting on me to find it. ...that has to come before $1300 carbs..for a bike that runs pretty darn respectable now.
