Typical full size kart will use 10 x 4.5 x 5 tires in the front and 11 x 7,1 x 5 in the rear on 130mm wide front wheels, and 210 mm rear wheels.October 31, 2015 at 3:25 pm #56111
you can try Axcel Fast Graphics they are 10 for $48 I believe.September 8, 2015 at 7:17 am #53964
I have learned that the Comer 80 works best when max RPM is in the low 12k range depending on the drivers ability throught the tight sections to carry speed.
If its same chassis, day, and driver, with a different motor I would look to the carb.September 7, 2015 at 10:03 pm #53960
Carb is the most likely issue. Try swapping the carbs.September 7, 2015 at 8:37 am #53929
The Ferodo Kart attack are and excellent pad, They have great bite and modulation even when cold with no fade when hot with increased bite that can still be modulated. They have excellent wear characteristics too!September 2, 2015 at 11:21 am #53775
When cold you will need to choke it by covering the airbox tube to richen the mixture. Also the added vacuum helps get the diaphragm in the carb pumping fuel as well. Dont give it any throttle until after it fires, this can take more than a few seconds when you first get to the track, after it has been running it should fire right up but still dont give any throttle until after it fires.
You might need to adjust the carb, A good starting point would be 1-1/4 to 1-1/2 turns open on the low needle and 1/2 to 3/4 on the high.
Also the carb should be cleaned regularly, dissemble the carb completely and clean the carb and all passages with carb cleaner, just carefully wipe clean the rubber parts, inlet needle and pump diaphragm. Clean the inlet screen and reassemble. There are some videos you can watch to learn how to do this.
Idle once warm should be high probably over 3000 rpm if it will idle.
You need to clean the plug if its a new driver and they aren’t driving hard at full throttle for most of the lap. An abrasive plug cleaner is recommended from aircraft spruce or harbor freight tools. Use a BR9EG when its not being driven full tilt and especially when outside temps fall below 75 degrees. A BR10EG is recommended for 75 and above when you are driving it hard.
It is normal for it to want to stall when coming off the track.August 6, 2015 at 7:42 am #52504
I would guess that you haver a twist in the chassis causing it to be heavy on the side it is turning towards.
While getting the steering shaft or sweep centered is improtant if the wheels are aligned the kart will still roll straight if the chassis is straight and weights are equal. The sterring wheel will just be pointed in the wrong direction.
To measure the sweep go to youtube and look at some of the videos there for instructions.July 21, 2015 at 10:56 pm #51702July 16, 2015 at 5:45 pm #51535
For racing you will want a Kid Kart not a Micro Kart. The Honda kid kart motor is what most are racing these days as well but it would be best to confirm with the local tracks and clubs you would race with. A Kid Kart chassis is never stressed much so they last a long time and buying used is a good option as well.June 26, 2015 at 8:20 am #50579
The Snell specification for youth helmets is CMR2007 and there is also a SFI 24.1 (??) specification.
A youth sized helmet is smaller and lighter and better for reducing fatigue in the neck.
Vega Trak in youth sizes is CMR2007

The motor builders will set the carbuerator for the fuel delivery curve that is right for the way the set up their motors. For driveability and maximum power the carb needs to be rich on the bottom and lean-out as the RPMs rise.
So a motor builder will set the pop-off pressure, fulcrum height and suggest needle settings according to experience or on the dyno.
Certain carbs will just flow more air and therfore they make more power but all can be made to run well. Some motor builders will set/adjust the throttle stop position for WOT at the point where the air flow is at its maximum.
I find that regular maintenance like daily disassembly and cleaning keeps it running good and reliably. Also I recommend a good fuel filter as debris really screws with the operation of a pumper style carbuerator
