Hi Martin,

The tip of the needle is included in the math when calculating the annulus of the tip/main jet area. This area (annulus) meters fuel at wide open throttle. At any position other than WOT, the taper/main jet/atomizer meters the fuel.

once it’s full throttle, don’t you see the huge difference between 132 and 162.

Yes.

Martin,

A K22 needle has a 1.80mm diameter tip. A K8 needle has a 1.50mm tip, .30mm difference.

I.E there is minimal difference in the annulus created by the needle tip/main jet between K22/168 and K8/140.

168/K22 = 138/K8. Both needles have the straight section diameter of 2.50mm

 

Different needles can have different tip diameters. The needle tip size is part of the equation when calculating annulus created by needle tip and main jet.

Probably better to jet a little rich if track has long straight(s).

An Emphatic NO!!! Not true. Only in a dream.

You can see the Honda contingent and the various brands of KZ karts.

The above BS by CR is indicative of the lack of knowledge by those who believe the stock Honda is the choice of champions. The KZ package is available in several brands and is just as reliable as the CR125, out performs it, cost is the same as a  ‘built’ spec Honda. I’m not sure what the difference is between bringing a KZ up to spec or a Honda up to spec. Let’s hear the facts not stories of the ‘old west’.

[Thomas Barth]

There’s enough room for both of them on our tracks.

 

Yup, why not score ’em together?

Hi Steve,

Assuming you were running DQ264/K93/128/CD1/60 jetting, not sure why you had a problem in the rain. I say this because I have never run that set up in the rain. Since you mentioned low end I would suggest that either the idle jet or atomizer were responsible for the hiccup, or maybe the needle height. On the other hand could it have been water getting to carb? The only way to find out would be to change either jet and see what the response was. Of course this is after the fact and not much help.

[Thomas Barth]

OK, OK, OK my issue with Honda:

Not a kart engine – I’m a purist

When a karter buys a Honda — somewhere a moto crosser doesn’t have an engine in his dirt bike!!

Honda CR125 bikes are no longer produced.

Honda engine is protected by the organizers by putting them in a separate class. Run ’em all together like the international races, 30 – 40 entries.

No kart specs for Honda.

Not an international engine – no CIK specs

[Thomas Barth]

Ya Bernie excuses are like a**holes, everybody’s got one. I do too. So here it is: KZ’s must weigh 410 lbs, wimpy Hondas 390. I’ll be the first to tell you that I’ll take weight reduction before horsepower any day! Except if the choice must be Honda

[Thomas Barth]

I don’t have a KZ at the moment but I’m looking for one.

To bad I can’t stomach the Honda. Lot of them for sale. Honda guys lookin’ for KZ’s

[Thomas Barth]

Sam,

They won’t let me tune their engines.

[Thomas Barth]

Bernie,

Did you check Sunday? Guess not.

Saturday was photo finish. Check the times please.

[Thomas Barth]

Wow!! I made it! Took a while but with some help from my friends wormed my way through the registration exercise for the new RH EKN format.

 

Now to get down to business—-Honda bashing!

It is still hard for me to understand why any self respecting karter would want to get into a shifter kart with an entanglement of hoses and wires, a exhaust pipe that is on backwards, then trust their skills to keeping the ugly beast on the track!!

A post about the cheap parts for the dirt bike engine forgets that there are no longer any engines being produced. A fact that does not give one confidence in future service or parts availability.

Just a week ago an ex Honda pilot showed his rear bumper to the reigning Honda king, Lance Lane . Congrats to Eric Chappell on taking his new Maxter to victory at the Grattan CES road race.

I have a question for the Honda tuners, do you tune the Honda or just use the forum to tune up your B.S. skills?

Anyway its good to be back on track – gotta luv KZ. P.S. almost forgot…trying to find a used KZ, emailed a karter to inquire if he would sell his K9B. He said he couldn’t – already promised it to a Honda owner who wanted a real ride!
