SG Motorsport is a worldwide distributor (outside USA) of Ivan’s  motorcycle performance carb jet kits for Suzuki, Kawasaki and Yamaha. These motorcycle carb. Kits have been designed (exception SV650) to run with the motorcycle’s OEM air filter. All jet kits come complete with needles, jets and any other carb. parts if any modification is needed to the motorcycle’s air box or air filter, full instructions are enclosed.

A word from Ivan:-

"It has always been my goal to get the most performance from whatever bike that I own. Running "good enough" has never been good enough for me. 

Excessive vibration irritates me. So does poor 'closed to part throttle' transition. Experiencing a lag when the throttle is suddenly snapped open while the revs are up can also be frustrating when trying to tune your bike for best
performance.

The reason that we got into Carb Kits is that we were tired of always messing around with the ones that are available elsewhere. It has proven to be a waste of shop time and inevitably, customers were not as happy as they could be.

All of my Carb Kits are thoroughly tested.

By 'thoroughly tested,' we mean:

• Buy the bike, as opposed to borrowing it.

• This ensures that there is no limit on the time and R+D that needs to go into the kit.

• Test it on my dyno

• Test it on the road against another bike, to verify the dyno.

• The dyno is not the last word, the road is!

• Make sure it runs as good in cold weather as hot weather

• Make sure it is smooth, on and off of the throttle

• Modify whichever carb circuit is causing a problem

• No circuit is safe from me!

• Do whatever it takes to make it as best as it can be...

• ...and offer it in one kit

• If there are small changes that need to be made to the needle or an addition angle ground on to it, I DO IT! Most of my needles have between 4 and 6 different tapers on them!!

• I do not release a kit for sale unless I am completely satisfied with how it runs at all throttle openings "

The Ivan's Jet Kit for the Kawasaki ZR-7 & ZR-7S  is the result of more than 4 months of combined testing. It has been designed for use with any exhaust system, stock or aftermarket, including the stock muffler.

An air filter cover modification was necessary to increase power above 6000 rpm, and the needles with their 4 angles are designed for use with the air filter cover modification.
The air filter cover modification diagrams and instructions are included with the kit.

Driveability is greatly improved, the common dead spot off idle is completely eliminated, and throttle response is immediate.

One of the common misconceptions with this model is that a larger pilot jet is needed….
We have found that this is not the case at all…….. Our needle design takes care of it.

Handlebar vibration is dramatically reduced (feels smooth as glass), and closed to part throttle transitions are also dramatically improved.

After installation of this kit, your ZR7 will accelerate hard until the rev-limiter shuts it down and will have awesome driveability.
