Okay guys, here it is. The new KDS plug-n-play injector. designed especially for 4-valve engines, it has dual spray cones with super-fast response and best atomizaton on the market today. The price will be right at $100 with new seals and adapter harness. This is a real improvement over the other designs we have available. Standard is 550cc and available in 630cc as well 8)

That is nice! You still da man Kenny :thumbs:
nice...
would that be useful in a stock build or really only good in big bore builds??
The duty cycle gets up too high on some builds near the 75 hp range (depending on the dyno and efficency of the build) at this point stock injectors will start to fail due to heat and the quality of the spray pattern will decline...
Those GENESIS injectors are a good replacement if u come to this point (though i have not tried them personally yet)

That is correct Daniel...... The spray pattern on these is still better than stock with lower power builds. The guy at us rally team is the builder of these injectors, and we have been working on a spray pattern and drop in kit especially for the Raptor, and other atv's as well. So basically this guy (Scott) is building them especially for my applications 8)

They work well in any size motor. I have been working with this guy because there are guys out there that see gains by going to a carb. That immediately tells us that we have atomization problems. We are also working up a billet fuel rail with a "dead head" fuel pressure regulator that will allow increases in fuel pressure without a return line. It can also be referenced to boost or n2o pressure, or works with part throttle vacuum to reduce fuel pressure under part throttle for cross country guys that need to stretch their fuel as far as possible :thumbs:
most of the gains from going to CARB are due to the restriction of the PLate and shaft area in the tb as well as turbulence
the reason say a 52mm carb will flow better then a 52mm tb....even going up in tb size u still have the plate and shaft messing with air flow and speed
Let us know when you've got some testing and results done on these injectors...power, fuel economy, throttle responce ect....
The flow doesn't seem to be the trick in my testing. It seems that everytime I use a big (52+) TB I lose more than I gain. Even though there is some gain in the overrev, the rest of the powerband seems to suffer considerably. But again it is important how you index the plate :thumbs:
its all about intake tube configuration and design....matching the length of the tuned area to the correct diameter.....it can make u go in circles trying to get the most out of it without sacrificing bottom.....
i have one tube design that works with the 52mm tb that doesnt lose any on the bottom tru mid and still gains up top, something i figured ot over the last few days.... :nod:
Kenz figured that out some time back........ I personally make more power everywhere with a tb that is smaller than a 52, but bigger than a 47 bored factory piece. Then add in a better injector and the motor comes alive. The good thing is that I am friends with the guy that builds the Genesis injectors. This thing really stands out. I was doing research for cross country racers that needed to make the power with less fuel, and it works very well 8) He is gonna be custom building these for all kinds of other motors (for KDS Racing).
I'm assuming they'll be just a direct bolt in?
How much and when can we expect to see them? Or still heavy on the R&D?

That is nice! You still da man Kenny :thumbs:
+1 your the man!
They are finally done..... The standard Genesis injector is the wrong size so the tip is custom built for the Raptor TB( Grizzly,Rhino,YFZ too),so it is a direct bolt in without any spacers. Can be had in 550cc and 630cc. Comes with new seal, o-rings and adapter harness. On the left is a modded factory Denso injector.

couple questions.
What is the cc of the stock injector?
What bene's are there to upgrading the injector for a mid/mild motor'd guy like myself w/ a 727?
being that it is CUSTOM MADE then why not put the OEM injector connector on it being that its the same for all the yamaha models, ???
just a thought :thumbs:

probably cuts some of the cost since you would have to buy a pack quantity, where as genesis already had that style in stock and had a good buy on them. looks good kenny, hurry up and answer krandal's question so i can have u ship one with that tb :nod:

They are ready now........I have 3 left......looks like they are gonna move fast. They are $125 as shown ready to bolt in. 8) No dyno testing yet. I feel like it is more of a formality at this point. I will be getting rider impressions and track times first.

Because we have to use coils and bodies that are already production pieces so we don't have to re-tool the entire fuel injection industry....... That would set us back a day or two, so we decided to use the ones with the fastest response time in the industry with the shortest down time. Even though it ideally has 550 cc like many others, it has much better atomization and spray pattern that will ultimately support more HP due to improved BSFC #'s.

You are correct sir.:thumbs:
when are going to prep a 750cc injectors?
what are the internal materials? as running methanol and Nitromethane mixture, Stainless steel internals will resist internal corrosion, thus making them injectors more of alky-friendly >:D
These use Bosch EV-14 internals.......The absolute best core Genesis can source....... The internals are alky ready. I'm not sure alcohol will ever stop creating problems. I have a really good fuel additive/upper cylinder lubricant that turns into a really high quality synthetic lube during the heat of combustion. Great for alcohol motors. :thumbs:

what about the 1st question? 750cc volume availability ?
Performance increase swithcing to this? ???
