For those that do not get IKF rule books, this is the rule that IKF wants to utilize starting in about a month. Those that purchased bumpers from David and I, we will be bring our welders to the track and tacking the bumpers solid if you would like. It was also stated to me the the solid bumper rule vs. flex can be at the race directors discretion..

Note the IKF BoD members that are looking after us racers and those looking after their business's and own pockets. Again just my .02....

This is a cut and paste from the IKF minutes on the IKF website..




Mike SchornRear Bumper Rule – he is asking the Board permission to allow flex in the previous bumpers to
be allowed in 2011. Only compromise he can see for his constituents. Scribner states there was
a lot of communication from up there and should speak volumes to the Board. Schorn asks
Cantrell if he has seen the bumpers; heard they had been modified. Verlengiere asks Motley if
there are any concerns about how it impacts the tire other than not complying to the rule; asks if
there are other issues with the design that make it questionable. Motley states there are concerns
with it because it allows part of the bumper to run into the tire; it does not have crush like the
plastic ones. Scribner states the plastic ones run into the tire too, Diederich says it does not have
the same effect as metal does. Verlengiere discusses the bumper Schorn showed to the Board
yesterday. Asks if it is rigidly mounted to the bar so when you hit it, it moves toward the tire.
Schorn says it can go against the tires and comes back up. Scribner states similar to a molded
plastic bumper would do. Schorn says the Rulebook says you can’t have plastic and has to have
a metal loop. Discusses bolting. Scribner says continuous is not in the Rulebook. Hilger states
that most must be drilled and pinned.
Steve Marso joins the Meeting.
Araki states that he has seen more plastics bumpers than steel bumpers come loose or come off
the karts on a regular basis. Motley states they are geographically different. Araki states the
problem is trying to control which one of the bumpers is .Motley reads “retention cables or
straps may be utilized however they may not compromise the original design or homologation of
the bumper and mounting hardware”. Verlengiere states there has been much discussion on this
previously and asks where the Board is at today; is Schorn asking for another vote. Hilger states
Schorn is asking to allow the bumpers Schorn brought to the Meeting through 2011. Lengthy
discussion by Board. Hilger reads the clarification of the rear bumper rule: the bumper may be
either CIK style plastic or continuous loop steel tube of double bar design. No flexible
components are allowed. Minimum diameter of .625” with .065” wall. The basic design must
conform to the following drawing. Hoegerl asks if the elephant ears are added, is it considered
continuous. Scribner replies yes when it is welded, it is allowed. If you add the word continuous, it
will have to be welded or change the verbiage to say it must be welded. Motley states that most
letters came from a narrow geographical area. Scribner feels they need to phase out the hinged
or flexed bumpers at a pre-determined time. Araki asks if they can approve the wording that full
width bumpers are mandatory in 2011 or whatever year and the rule that Motley writes will be
effective January 1, 2012. Scribner agrees with Araki. Want to eliminate the small bumpers.
Allow a transition period to get through the season. Motley suggests to not require the full bumper
in 4 cycle.
Araki states that, according to how he reads the Rulebook, the bumpers are legal. Scribner
agrees with Araki. Motley says to consider the intent of the rule despite slight flaws in the
description.

Note dimensions shown are for adult chassis only, Cadet and Kid Kart must extend to at
least center of rear tires and the ends shall not extend beyond the outside of the rear tires,
except in a declared rain race.
The rear bumper may be either CIK style plastic or welded steel tubing loop, of double bar
design. Welded on "elephant ear" extensions are permissible. No flexible components are
allowed.
Minimum diameter of steel tubing must be .625” with a minimum .065” wall thickness. The basic
design must conform to the following drawing: (Note the requirement for the lower bar in Section

If steel tubing utilized, the rear protection shall extend to at least the center of the rear tires. The
ends of any rear protection may not extend beyond the outside of the rear tire/wheel assembly

However, they may not compromise the original design or Homologation of the bumper and
mounting hardware.

You know, not that I would consider it, but it I had one of those hinged bumpers I would leave it hinged, tack it and make it continuous to meet the rules, but if that tack was small enough when it got hit hard enough it woul break the tack instead of bend the bumper and then when you get back to the pits you simply have to tack it back in place and all is good again. Like a break away bumper....just my .02. but then when you add my IQ u end up with less than .00002 pasos.....so take that into consideration any time I open my mouth!!! :-)
