Historic Karting Regulations

1. INTRODUCTION.

Despite the original wish to avoid rules and regulations for historic demonstrations, it has become clear that in the interest of the health and safety of those involved as drivers and anyone otherwise involved with demonstrations that some basic rules are essential.

In these regulations, ‘the club’ refers to the British Historic Kart Club.

 

2. ADMINISTRATION.

All events fall in to two basic categories, those organised directly by ‘the club’, and those organised by others to which ‘the club’ is invited.  In either case these rules must be considered as mandatory and part of any regulations issued for the event.

Where ‘the club’ is invited by an MSA or CIK approved organisation, members are also bound by that organisation’s General Competition Rules, Supplementary Regulations, Additional Supplementary Regulations and Permits as issued by the organisations. Technical and kart specific regulations will always be those published by the British Historic Kart Club.

 

3. EVENTS - DEMONSTRATIONS.

Demonstrations will fall into four types. Static display, parade lap, restricted display and unrestricted display.

Static Display

Any event at which 'the club' is invited to display karts without driving. Typically, such an event would be one of the motor shows that we attend.

Parade Lap

Any event at which we are asked to drive at reduced speeds and probably behind a pace vehicle.  Such an event may not take place on a closed circuit.

Restricted Display

Any event where we are permitted to drive at higher speeds but the top speed is restricted by a pace vehicle. Such an event would be the demonstrations carried out at the British Kart Grand Prix at Cadwell Park.

Unrestricted Display

Any event at which we are permitted to drive at full speed without a pace vehicle. Such an event is the Shenington Revival Meeting.

 

4. RULES FOR DEMONSTRATIONS.

Static Display  

It is important that all members behave in a fitting manner at all times.  You will be dealing with members of the public and it is essential that we present the best image we can at every opportunity.  Do not forget that the person you are talking to may have the kart you want to buy.  All karts should be displayed in the best possible condition, clean, tidy and as near original as possible.  All karts should be displayed with a Data Sheet giving as much information about the kart as possible in a clear and precise way.  A basic sample Data Sheet will be available on the club web site.

Most non-static displays will also include a static display and the above will all apply.

Parade Lap

All drivers must remain behind the pace vehicle and drive in a sensible manner. There may not be room for safe overtaking and you may be in close proximity to the general public.  Great care should be taken in these situations and no undue risks should be taken.

Restricted and Unrestricted Displays

When a pace car is used the parade lap rules apply.  At all other times all drivers must be aware of the potential risks and whilst driving at full speed is permitted on a full display, care must be taken to avoid any incident with other drivers and to stay on the track.  Drivers must be especially mindful of the difference in speed of karts from the various eras.

 

5. PROTECTIVE CLOTHING.

The protective clothing regulations described below are an absolute minimum.

Static Display

Members are encouraged to wear period costume at such events. Club shirts or similar also enhance the presentation of any display.

Parade Lap

Members are encouraged to wear period costume at such events.  Dependant on the period of the kart or karts being demonstrated this could vary from a boiler suit and a pudding basin helmet to leathers and a modern helmet.

Restricted Display - Short Circuits

A good quality race suit and helmet must be used.  The clothing may not meet current MSA standards but should be similar and in good condition.

Restricted Display - Long Circuits

Leathers must be worn and an MSA approved helmet must be used.  The clothing must meet current MSA standards.

Unrestricted Display

As a minimum protective clothing must meet the standards for a Restricted Display and it is recommended that the current MSA standards are met in full.

MSA Regulations for Kart Clothing

For Long Circuits all drivers must wear leather suits or suits approved by the MSA for Long Circuit kart racing.  For Short Circuits, leather, heavy duty PVC suits, approved by the MSA for Short Circuit kart racing, or suits bearing the CIK homologation label dated after 1997, are acceptable.  Leather suits must have a minimum thickness of 1.2mm measured at any part of the suit.

MSA approved crash helmets for kart racing must be to one of the following standards:

FIA 8860-2004

SNELL SA2005

SNELL SA2000 (may be withdrawn with effect from 01/01/11)

SFI Foundation 31.1A, 31.2A

BS6658 Type A/FR

SNELL K98 and K2005

SNELL – FIA CMR2007

SNELL – FIA CMS2007

 

6. RIGHTS AND DUTIES OF ORGANISERS.

In addition to any regulations placed on us by any organisation inviting ‘the Club’ to an event, ‘the Club’ shall be entitled to refuse any entry, waive or return any entry fee, divide demonstration runs into ‘heats’, amalgamate classes, check eligibility of karts and drivers and publish mandatory instructions to drivers.

‘The Club’ can also distribute awards at their own discretion; change the order of events, cancel or abandon a demonstration, delete or amend part of the course and permit a change of driver or kart.

‘The Club’ is responsible for compliance with these regulations and any instructions issued. ‘The Club’ is also responsible for additional regulations, entry forms, programs, lists of drivers and ensuring compliance with all required regulations.

 

7. HISTORIC KART LICENCES.

Historic kart licences will eventually be required by all drivers as there is a need to prove and approve driver’s ability. BHKC licences will not be expensive, not need a medical and will be like a 1960’s licence.  CIK approval is being sought for these licences.  A driver’s licence will be endorsed or revoked if any driver is found guilty of an indiscretion.

Kart licences will be issued as National and International status.  Holders and former holders of MSA Kart race licences will automatically qualify for an International Licence.  Non-holders will qualify for a National Licence which will be upgraded after three successful observations by nominated club members.

 

8. ENTRIES.

Entries will be required for ALL MEETINGS.  These may take the form of registration for minor events but for larger events a full entry form will be required complete with the required entry fee at least 7 days prior to the event.

 

9. DRIVER CONDUCT — GENERAL.

All drivers must act in a responsible manner at all times. Gentlemanly conduct must be the rule of the day.

Karting is described as a non-contact sport but with the speeds involved and the closeness of driving it is inevitable that incidents occur. Because of our motto, ‘Preserving kart heritage’ it is essential that we are extra careful in avoiding incidents and we do not have the excuse of ‘race incidents’ as we are demonstrating, not racing.  If necessary, the Committee will take action in case of any infringements of this rule.

Where we are ‘invited’ to a meeting, the organisers have the right to take action in the case of poor driver conduct.  Where this occurs ‘the Club’ may be involved in preventing any further occurrence or future problem.

 

10. DRIVER CONDUCT - SPECIFIC.

When permitted, due to small attendances Classes may be mixed.  On such occasions gear box and non gearbox karts will use a common circuit.  Gearbox drivers must give way to non-gear box in all corners and allow them room to take their own line.  This is a simple way to ensure incident free demonstrations.

A similar situation will also apply when karts of different era’s and power are on the track at the same time.  Respect the other driver and back off rather than knock off.

 

11. FLAG SIGNALS.

Flag signals must be obeyed at all times. Failure to do so will lead to disciplinary action.

All flag signals will be in accordance with current MSA regulation J16 with exception of start and finish flags.

National flag - Stationary

Indicates the demonstration has started.

Black and white chequered

Indicates the demonstration has ended.

Blue flag - Stationary

Another driver is following close behind.

Blue flag - Waved

Another driver is about to overtake.

White flag

A service car or slow moving car is on the circuit.

Yellow flag - Stationary

Danger, slow down sufficiently to ensure that full control of the vehicle can be retained.  No overtaking.

Yellow flag - Waved

Great Danger, slow down considerably.  Be prepared to suddenly change from the projected racing line or take other evasive action including stopping if necessary. No overtaking.

Yellow flag with red stripes - Stationary

Slippery surface ahead.

Yellow flag with red stripes - Waved  

Slippery surface imminent.

Green flag

All clear at the end of a danger area controlled by yellow flags. Also used to signal the start of a formation lap and shown at all posts during first lap of each practice and during formation lap.

Red flag

Immediately cease driving at racing speed and proceed slowly, without overtaking and with maximum caution to pits or start line obeying marshal's instructions, and be prepared to stop should the track be blocked.

Black flag with orange disk

Displayed with drivers number Notification of apparent mechanical failure or a fire which might not be obvious to the driver.  The kart concerned must return to the pits for repairs on the next lap.

Black and white rectangular flag

Displayed with drivers number: A warning to the driver that his behaviour is suspect and he may be Black flagged on further reports.

Black flag

Displayed with drivers number: The driver must return to the pits within one lap of receiving the signal and report to the clerk of the course.

KART REGULATIONS

1. GENERAL.

All karts must comply with the regulations in force at the time of manufacture of the kart. This is currently not easy to operate and ‘the club’ is requesting that any member who has a copy of any old Blue Book Kart Regulations to allow us to copy the book to build a reference library.

‘The club’ has decided to introduce some specific regulations in the interest of safety.  In practice this is actually back dating certain regulations and we feel that members will accept them as sensible actions.

 

2. SPECIFIC.

All karts must be fitted with adequate chain guards, in particular, adequate finger protection on direct drive front sprockets. Simple plastic guards are available for this purpose from kart traders.

All karts using glass fibre seats must have a minimum 2” diameter washer fitted between the seat and any rear seat supports.

The practice of using solder-less nipples of any type on brake cables is not recommended, however if this is the only alternative they must be fitted in accordance with Data Sheet BI-IKC 002

All karts at all events must carry number plates representative of their age and class.  A front number plate is to be fitted as a minimum requirement.  A record of preferred numbers is being assembled by the club in order to prevent duplications but the same number on different colour plates will be allowed.

 

3. SILENCING.

To ensure our access to all race circuits it is important that we keep our noise levels to current MSA levels.  ‘The club’ is well aware that this will be difficult for some engines and we have tried to write the following to help.

For demonstrations, supplementary silencing of a temporary but secure nature may be fitted in order to reduce noise levels to an acceptable level.


For many direct drive karts the addition of a ‘TKM’ or ‘Decibel’ end can to the current silencer plus some form of inlet airbox or filter may well suffice.   For less adaptable engines like those with integral silencers, a complete bolt on alternative may be necessary.

Gear-box karts have a similar option, the use of a modern silencer or similar device, coupled with an inlet box or filter similar to what 210s use would work well.  When selecting a silencer, be aware that the number of right angle bends is specified in current regulations for a reason, they are quite effective in silencing.  Also as the exhaust gasses leave the tail pipe, each successive pipe needs to be larger than the preceding pipe to avoid power loss.

The design and fitting of any supplementary silencer may be of a temporary nature so as to be removable for display purposes. When fitted for demonstrations this equipment must be safe and secure.

 

4. ELIGIBILITY.

This system follows the pattern used for cars in historic motor sport.  It is largely based on tyre width and chassis design changes occurring at the class date changes for each period. Watercooled engines are excluded except for the Vega VIC 19L, the John Dent Villiers conversion and the Paul Biagi Bultaco conversion.

Veteran

Up to end of 1963

To include those models in production prior to the end of 1963.  Some models may have continued into the Vintage period and are therefore eligible for inclusion as Veteran karts.


Veteran karts will run tyres not exceeding 4” wide across the shoulder section of the tyre.  

Vintage

1964 to end of 1971

Including those models that went into production after the start of 1964 and prior to the end of 1971. Some models may have continued into the Historic period and are therefore eligible for inclusion as Vintage Karts.


Vintage karts will run tyres not exceeding 5” wide across the shoulder section of the tyre. Class 4 karts are permitted to use rear tyres not exceeding 6” across the shoulder section of the tyre.  

Historic

1972 to end of 1977

Those karts that went into production after the start of 1972 and prior to the end of 1977.  Some models may have continued into the Classic period and are therefore eligible for the Historic class.    


Historic karts will run tyres not exceeding 6” wide across the shoulder section of the tyre.  Class I karts may only use rear axles up to 1 inch diameter and the overall width of the kart must not exceed 1100mm.  

Classic

1978 to end of 1982

Those karts that went into production after the start of 1978 and prior to the end of 1982.   Class I karts may use rear axles up to 30mm in diameter and the overall width of the kart must not exceed 1300mm.  

Classic karts may run tyres exceeding 6” across the shoulder section of the tyre. Historic karts with tyres wider than 6” will be considered to be Classic karts.
