Removal of Engine Seals

W60 engine seals can only be removed by approved personnel. If a customer takes an engine to a sealer without the seal intact, they are not permitted to reseal it. This engine must be returned to Zip Kart, who will inspect the engine and at their discretion only reseal if they are happy with all contributing circumstances.

 Here are a few tips on running your Comer W60

Petrol Oil Mix

The following amendment needs to be made to Page 6 of the Kart Race Year Book, A1.4, replacing the sentence beginning engine lubricant:

Engine lubricant must be a synthetic oil meeting the requirements of the JASO FC standard to ensure that the engine exhaust emissions meet the standards set down by the MSA. 'JASO FC' is to be clearly marked on the lubricant container and is available from the majority of oil product manufacturers.

Carb Settings 4 the Tillison

Set jets by turning in until lightly seated closed, then turn out the low jet 360o and the high jet to 260o. This setting will give reliable performance, use of a washer soldered on the high jet (must not measure more than 12mm OD) is recommended to enable the driver to control the mixture to give optimum performance. 

However in testing we found if the carb was leaned in less than 260o on the high jet  the performance fell off. Therefore the carb required little or no adjustment as the engine runs at a consistent temperature giving consistent lap times. 

Warning! Use of the washer on the high jet is recommended for experienced drivers only as adjusting the mixture incorrectly can cause seizure. Always pre filter fuel mix through a coffee or paint filter before filling up your tank.


 
Keeping a log

Always keep a log of running times for each of your engines as this is very important information not only for yourself but also for your engine builder. 

 

Gearing

The gearing of the W60 is very different to its predecessor (S60) we found whilst testing the gearing was 4 to 5 teeth less 

 

Spark Plug

With immediate effect only the following spark plugs are permitted to be used for the W60 engine:  1. Bosch W2AS   2. Bosch W08AS

      Air Box

There  is an amendment to the regulations to allow a gauze or mesh to be attached to the external face of the air box trumpet. This must not alter the shape or size of the trumpet venturi. N modifications to the airbox or trumpet can be made for the purpose of attaching the gauze or mesh. the maximum thickness of the gauze or mesh permitted is 1mm.

British Club engine

In 2004, clubs will be allowed to run the W60 & S60 in the same event. This will effectively create a Cadet A & Cadet B formula. Clubs will be expected to give trophies to both S60 & W60 drivers

Work is on going to establish a major national championship for 60 drivers

 

 Here are a few tips on running your Comer S60

Petrol Oil Mix

Cold weather 250cc oil to 5lts of Super Plus Unleaded. Hot weather 280cc of oil.

Carb Settings

Set jets by turning in until lightly seated close, then turn out the low jet 360o and the high jet to 260o. This setting will give reliable performance, use of a washer soldered on the high jet (must not measure more than 12mm OD) is recommended to enable the driver to control the mixture to give optimum performance. 

Full power is obtained from the Comer when the low jet is at 360o and the high jet is 220o to 230o. 

Warning! Use of the washer on the high jet is recommended for experienced drivers only as adjusting the mixture incorrectly can cause seizure. Always pre filter fuel mix through a coffee or paint filter before filling up your tank.
 
Keeping a log

Always keep a log of running times for each of your engines as this is very important information not only for yourself but also for your engine builder. the head volume will decrease when carbon deposits build up, the legal requirement is 6cc min. You can check this yourself, alternatively get your engine checked by your engine builder prior to racing.
 

Gearing

There is no hard fast set rule to this, consult your engine builder to advise on circuit sprocket to suit each particular engine and driver.
 

Spark Plug

Bosh WS5F may only be used.
