You're not going to be racing KZ2 at Supernats.

Cesar,

SKUSA is the sanctioning body that puts on the annual SuperNats. The SuperNats is an annual event which has for many years included the KZ2 class which typically includes many of the top factory team ICC/KZ drivers in the world. It's not a class for the newbie...!!!

KZ2
Engine: ICC
Age: 15+
Weight: 385lbs
Tires: MG-SK spec tires from SKUSA
Fuel/Oil: VP MS98 + Motul Grand Prix 2T

G1 is the same as KZ2 except the minimum age is 30+ yrs old and 405 lbs.

Over the last few years many G1 drivers have migrated to S4 (Spec Honda) leading in part to the discontinuing of the G1 class both regionally & nationally. Hopefully G1 will make a comeback... (that's a discussion for another thread).

See this thread for some discussion of the discontinued G1 class at the SuperNats:

http://ekartingnews.com/viewtopic.php?t=117548&postdays=0&postorder=asc&start=0

All this being said, yes there are pockets of ICC/KZ racers throughout the country... but you must look into the tracks and sanctioning bodies that you will be racing with. Not all of your questions can be answered online...

My best suggestion is for you to walk the paddock at a couple of races and talk to as many of the shifter drivers as possible and pick their brains to find out their opinion of which engine is the way to go both short & long term.

You admitted in an above response that you just went to Homestead and saw mostly Honda's with some ICC's. This goes to show you that the Honda continues to grow and would probably be the best choice for you right now.

Maybe you haven't been to many tracks. I'm sure there are places where there are lots of euro motors. But out here you'd be racing against yourself if they even let you go out.

And that's the point Tom. This guy is asking for advice. Not a political or religious diatribe. The single best thing you could have told him, and what you should have told him, would be to go and buy the motor that is the most common in his area.


Joseph, you so full of B.S. I'm surprised that you still can breath. I have been to more race tracks than you'll ever get to if you live to be 110. Your problem is you're stuck in CA where the Honda is national shrine. I AM partial to the KZ, It's a real Kart engine. I do not want any one out in the audience to think that I would ever steer a prospective karter to a dirt bike engine. There are absolutely no good reasons to encourage anyone to buy a dirt bike engine. Especially the low cost, low maintenance B.S. (KZ's never need new crankshafts, just replace lower end at a reasonable cost). Without getting into a show all tell all about the benefits of the KZ, I can assure you that there is no cost benefit to using a DBE. Besides if you are looking for the enjoyment of competing with a mini F1 never, never, waste a red cent on a DBE.

Joseph, I am giving Cesar good advice "stay away from the wolf in sheep's clothing" Do not ever believe that a 'low cost, low maintenance DBE can be substitute for a real fire breathing kart racing engine. If you're going to take the plunge go with the best. Remember, nobody ever said racing is cheap.

Tom, what is the average cost to get a KZ crank rebuilt? How many gallons/run time before it needs it? Does that include a new connecting rod?


OEM Honda 1999 CR125 Crankshaft assembly (comes with con rod) - ~$200 (I found it from $180 to $230)

Not to mention a properly built crank means all the world in HP, and there's only a handful of people on the planet that can do it correctly......

The mind of Tom Barth: spend whatever it takes even if there is no one to race against. Great advice.

^ thank you.

how long should it take to install a motor package in to a chassis, or better yet, how long should a shop charge me in time to do the above.

Taking your time, a few hours.

It really depends on what all you need to install. Does the kart already have fuel lines, control (throttle & clutch) cables, data sensor cables, chain, sprocket, radiator, coolant hoses, etc...?

If you are just taking the base engine (Motor mount, engine, carb(attached to engine), exhaust(for a moto)) off, then you should be able to do it in 15 minutes pretty easy.

Setting up a new powerplant on a new(to you) chassis may take half a day or more to get everything just right.

Basically. If you're relatively mechanically inclined, of course. It was a pretty straightforward installation process the 1st time I did it myself, & I had zero prior experience. Actually, probably the biggest thing in my mind was making sure I had the correct miscellaneous hardware (fasteners, lines, etc.).

It's best to think it through & don't be in a rush to just finish it. Look at other examples at the track & note what works. You can learn a lot from other people's examples/experiences if you take the time to look. There are good/better/best ways to do little things that make a big difference.

I was going to ask Tom B. how advising a newbie to the sport to get a KZ is good advice, but now it makes sense. Very Happy

I have a TaG-ICC. It has the durability & rebuild intervals in line with the CR125, but it's an ICC-type engine built to bolt straight in to the chassis. Best of both worlds, in my opinion.
