ABkC News September 2000


New rules, new tyres and a new class…

Formula Libre, the all encompassing 100cc club class was formally endorsed at the ABkC’s steering group meeting at Motor Sports House, along with a host of other changes.  And 100C will appear under the resurrected name of 100 National.  The Libre class will permit more or less any 100cc 2-stroke, from Formula A, ICA, 100 National or Piston Port with any butterfly carb having a bore of not more than 24mm.  Wet tyres from Formula A, ICA or 100 National will be permitted, but a new slick has been chosen after exhaustive tests over the summer.  The slick chosen is the Dunlop SL4 and they will be available for 100 or less plus vat per set.  The ABkC would like to thank all the tyre importers who put forward tyres for testing.  The weight in Formula A goes up to 145kg, in line with the 2001 CIK regulations, so whilst ICA remains the same, 100 National is increased to 150kg which will also be the weight for Libre.  Similarly the ‘heavy’ class weights will increase from 160 to 165kg e.g. 100 National/165 will replace 100C/160.  Clubs will need to decide whether to run the separate ICA and 100 National classes, or change over to Libre and perhaps get bigger grids.  ICA and 100 National will continue to run in the Super 1 however, and Libre will not be permitted to have any national championships or seeded numbers.  Seeds from the other classes can use their cherished numbers, in the preference Formula A, ICA and 100 National.  The Winter Series will run as Super Libre, but this is just an amalgamation of Formula A and ICA, and is not referenced in the Gold Book. 

No JICA Restrictor for UK in 2001 and more…

After careful consideration the UK will not be introducing the CIK 18mm restrictor for JICA.  On the continent JICA has been trading lap times with Formula A, but this is not the case here.  We use harder tyres, the age limits are higher and our weather conditions are different too.  Also we have a well trodden history of following new CIK regulations by a year, to give time for further consideration.  However ignition kill switches will be compulsory for JICA.  The proposed 20mm restrictor for CIK ICA has been dropped.  Additional fuel filters, except within the tank, will be banned in Cadet Comer.  Honda Cadet will use the same tyre as the Comer Cadet, the Dunlop SL3 with RAC moulded on the sidewall.  For Junior Rotax UK, the reed valve block will need to be included within the sealing wire by the end of March.  Batteries will no longer need to be original types for Rotax.  Junior Rotax UK will have red number plates with white numbers.  Where Bridgestone YEQ tyres are used for Rotax Junior UK and JICA they will need to have RAC or MSA moulded on the sidewall.  The Rotax slicks and wets for 2001 need to be marked JAG, but the current tyres marked NJR can be used up until the end of March.  Incidentally the Vega W3 tyre no longer appears as an option in for instance 100 National and Europa.  The slicks for ICA change to Bridgestone YGB, with RAC or MSA moulded on the sidewall.  A new period of homologation series will be eligible for 100 National, (engines homologated for use in Formula A 1998 – 2000), but it should be noted that the special Super A water cooled engines used in the European championships during 2000 are not to be permitted.  In 100 National the slicks change to Vega XSL, marked GB on the sidewall.  This tyre is getting rave reviews.  The current slicks in these classes may be used up to the end of March, except in Super 1 qualifiers and so on.  100 National will now be permitted any butterfly carb up to 24mm bore, the same as in Libre.  Formula Green has been removed from the Gold Book and it should be noted that Libre is also an NKRA class.  The MSA remarked that the Ecomoto class would be incorporated into the Gold Book for the first time.

Gearbox class changes…

Now to the gearbox classes, where the proposals from the sub group had their final tweeks and ratification.  New engine registrations are being accepted in 250 National and National 125.  In the latter, the window of registration will be held open to allow importers to put in engines from the new CIK homologations for ICC.  125 Open in future will allow for any registered Formula C engine.  This means only rotaries and reeds that have been registered into the class by the start of 2000, no new registrations are due until for the 2002 season.  But the CIK and hence the ABkC will also allow any homologated ICC reed valve engine in 125 Open.  These engines would not have a cassette gearbox, and will have homologated gears.  If anyone used such an engine, it could not be used in National 125 unless it had been registered with the MSA for that class.  125 Drivers in the Super 4 national ABkC championships will have to carry CIK style bodywork although a bubble can be used instead of a Nassau panel.  Front noses must not be ‘wedge’ shaped.  This CIK style will become compulsory across the board for 2002.  The method of fixing is free.  After studying the outcome of the weight survey, the National 125 weight is going up to 180kg, and it may also increase by 5kg in long circuit.  The new engines for National 125 must be available for 1850 plus VAT complete with ignition but not including carburettor, engine mount, silencer or exhaust.  Gear ratios are to be ‘free’ for 250 National.  In that class, the Maxxis XP5 slick tyre used from 1st April will need to be marked X52 and only WT4S wets can be used.  Short circuit weight is increased to 195kg, and long circuit weight stays at 200kg in both 250 National and International.  The minimum wheelbase for both these classes will be 106cm. 

Transponder meeting

The mandatory use of transponders for 2001 by ABkC clubs has been widely forewarned.  But the steering group recognise that some of the less affluent clubs may not be able to afford the system just yet, so these clubs can apply for a waiver.  The MSA will be starting the necessary procedures to have compulsory transponders across all clubs.  A meeting with HS Sports is being set up for 6th December, probably at Whilton Mill.  All clubs are invited to send representatives. The day will include presentations and discussions on the use of the system, problems that can arise and the solutions to them.  The ABkC hopes that this meeting will be of assistance both to those who are already running transponder timing, and to those who have not yet made a purchase.

Miscellaneous changes to the Gold Book

Sprocket protectors will be permitted in any class.  It will be made clear that if the engine of a kart is running on the grid, the driver must be properly seated in the kart.  The ABkC will be making a strong recommendation that all drivers and trackside officials must use ear plugs or ear defenders during racing.  There is a lot of concern about the loss of hearing due to motorsport activities, especially in youngsters.   It is not just engine noise, wind noise passing the crash helmet also plays a part.  Also it is mandatory for all competitors to have an approved size fire extinguisher at race meetings.  This would need to be a minimum of BSEN3 standard with a 55B size rating.

International rule changes

Drivers racing Internationally and in our International classes such as Formula A, JICA and ICA should note some of the changes in the 2001 CIK ‘Yellow Book’.  All wheels must have bead retention with three pegs a minimum on the outside of the rim, and the inside for ICE and Formula E.  Radiators cannot be further forward than 55cm in front of the rear axle.  Side pods cannot be cut, except for a hole for JICA starters.  A safety cable must be used across the brake rod, or the existing cable doubled up.  Water pumps must be axle driven, but we are seeking a clarification as engines in ICE and Formula E have integral pumps.  Fuel tanks in these two classes will have to be 18 litres minimum, but that will not be necessary in our UK equivalent classes.  Numbers in all International classes have in future to be of an Arial font, so fancy or ‘digital’ numbers will not be allowed.  Crash helmets in the CIK championships will have to weigh less than 1800 grams (Seniors) or 1400 grams (Juniors).  Leather overalls are again permitted, so long as they comply with FIM standards (1.2mm thick). 

Control fuel, noise and judicial

There was a lot of discussion about control fuel, and whether a lower octane fuel for the TKM and Rotax classes could work out cheaper without unnecessary complications.  Contracts for next year will be negotiated soon.  The ABkC was concerned about the award of the Kart Grand Prix for another three years without any wide advertising of the tender.  The trophies at this years event also came in for some criticism.  Clarification about the new visor rule was sought, and the MSA said only if a visor changes a flag colour will it not be permitted.  A visor standard is recommended but not mandatory.  A date will be set soon to phase out the old type of kart suit.  It will give at least another two years of life.  ABkC clubs will be asked to use the 3.6m height for their noise meter from 2001.  ICA and Formula A lose the waiver allowing a higher limit, and drivers in these classes will need to pay very special attention to noise reducing measures, or change to water cooled engines.  Novices will be permitted in Junior Gearbox from January.  Some clubs have expressed uncertainty about the rule for 15 year olds in the year of their sixteenth birthday starting in Senior classes.  The MSA clarified that they must have raced in Juniors first, but could be still a novice.  Some clubs are in great danger of losing their track licences because they have not yet carried out improvements requested by the MSA, despite repeated warnings.  The Motor Sports Council have given approval for the judicial points system which is being trialled in Super 4, to be used in Super 1 next year.  A number of points are awarded for misdemeanours, depending on the severity of the offence, and every four points earns a ‘signature’ on the driver’s competition licence.  Twelve points would see the licence withdrawn.

Subscriptions and the AGM

Beccles and District Kart Club have rejoined the ABkC and were welcomed back.  It was confirmed that subscription fees for 2001 will remain at the current level.  Ulster Kart Club, the team managers and co-ordinators were all thanked for their tremendous efforts in making the Inter Nations Challenge such a success.  Next year it visits Wales.  Team managers are to have a meeting on 7th December, following the transponder system get together.  Clubs are asked to bid for the 2001 ‘O’ Plate meetings, including the gearbox and Formula A events.  All clubs should note that the Annual General Meeting of the ABkC will be held on the Saturday afternoon at the Trentham Gardens International Kart Show.
