This kit removes the rear airbox and installs a single large BMC or K&N filter - adding MUCH more airflow and improving power - almost to the level of the Config 30 kit. Includes Factory Pro design Carb Recal Kit, adapter ring and filter. User must devise battery hold-down method. Zip-ties and straps are commonly used. The kit includes Celmat 30 needles, several sets of main jets, alloy steel allen float bowl screws and more. This is a drop-in kit and requires No slide drilling.

I have worked on carbureted
engines for years but this is the most comprehensive kit I have ever
used. Really helps you see the potential of the CVK carburetor.

Ignition Advance Rotor - add more low and mid (it actually makes better topend, too) |

Ignition Advance Rotor Adds significant power at ALL part throttle
positions. That equates to more "snap" in throttle response for you!
Bolts on easily with hand tools. No adjustments necessary. Alright!
So the bike is running the nuts
now. Oh yeah!
Took it to the ZRX rally (KOTF) in
NY. I put on my ignition advancer and turned the mixture screws
in 1/4 turn and it's pulling 3rd gear power wheelies over rises
now. Can't ask for more than that out of a 500lb bike. I'm still
going to put a carb sync set up to get a little better low end
response but all and all I'm very happy.
Thanks for all your help Marc.

Need snappier shifting with fewer missed
shifts? Yes - this bike
You can remove the output shaft seal and the cover will come off. You'll have to replace the shift cover seal. though. If you remove the seal AND trim the top of the sprocket (slightly messy), the cover will def come off, though. |

Hi Marc
I've fitted the kit with the recommended basic settings which seem to work well (although i've only tested the bike for an hour so it may be early days).
It accepts full throttle from 1000 RPM in top gear!!!! something it never did before. There is no power band now, the bike just pulls at the same rate (arm wrenching) from idle to redline.
I'm too scared to carry out the procedure for determining correct main jet size on Britain's roads, but the bike did reach an indicated 150MPH and climbing when i lost my nerve due to very light front end, and drizzly rain starting to fall.
The bike pulls so cleanly and evenly, it feels totally tame. although it's faster than it was before.
God knows how you design these kits, but they sure do work, almost too well!
I can't believe the linear power, it's so even. Thought i was in fourth gear a couple of times, when in fact i was in fifth!
If the fuelling is this accurate, i expect there'll be an improvement in gas miles if i slow things down a bit.
After the Dynojet kit fiasco, the results with yours are truly amazing and much appreciated
Thanks
Bob
PS I haven't fitted the advancer yet, hope this won't mess with the settings.
ANSWER: Probably not. Maybe just a 1/4 turn more on the fuel screws. Unless the bike is too lean at some place, the advancer won't make it run poorly. marc

Just wanted to thank you for the quality of your work. I have the Factory Pro Jet
kit, K&N stock replacement air filter, and Yoshimura slip-on. Your recommendations
were right on. Bike has perfect throttle response. Thanks again.

00'Green.
D&D full exhaust, with alum. canister.
Factory Pro Config 10,100 mains, needles in third notch with one washer under clip
.
Mixture screws out 2 2/3 turns. (yeah, yeah. I know, but that's where they ended
up when right.)
K&N replacement filter.
Gutted Snorkel and trimmed back 1/2".
Smooth, seamless power delivery from idle to past redline and much "stouter" than
stock.

Just a quick note to tell you what a fine job you do on R&D. I just installed a
ti kit in my 99 ZRX (Kerker slip-on, K&N filter, foam removed from snorkel
throat, and trimmed side cover). 100 mains, e-clip on 3rd slot, and 2.5 turns on
mixture screws. Pulls great from idle to redline using your recommended base settings.
By the way my other 3 bikes (98 VTR,97 Bandit 1200s, and 94 CB1000)have had the
same results with your kits. I never even consider purchasing kits from you know
who.
Thanks again for well researched products.
John

Marc,
I got the 1.0 kit, and I have nothing but good things to say about it.
The directions could not have been easier, and the initial recommendations proved
to be so good, I don't think I will mess with it. I have yet to dyno the bike, but
it pulls real good, much better than stock.
I also have:
Muzzy megaphone
K&N replacement filter
I have not trimmed the side cover, but I did remove the cage and foam from the snorkel.
If I go with Ted's advancer, will I need to go up to the 102's? ( to help prevent
detonation)
Thanks for such a great product.

Question:
A number of ZRX owners (with stock cams and a variety of pipes - not Yosh) have
posted dyno results with a pronounced torque dip at about 5000 RPM.
Can you tell us why that happens?
Just wanted to thank you for the quality of your work. I have the Factory Jet kit,
K & N stock replacement air
filter, and Yoshimura slip-on. Your recommendations were right on. Bike has perfect
throttle response. Thanks
again.
Answer:
If we check out a bike and change a couple things, perhaps I can shed some light
on the subject.
If the torque drops at an rpm during a steady state test (not a sweep test), and
the 4 Gas readings indicate a
mixture problem, perhaps, by addressing that fuel problem, we could "fix" the torque
problem, though, there's
not much in a carb that affects only 5k.
It's possible that it is the pipe, possibly aggravated by intake tract length -
possibly a few more issues, too.
What is common to all the bikes with torque drop-off problem?
Pipe brand?
jet kit brand?
Stock airbox?
Individual air filters?
