Spark plugs are a vital component in any high performance two-stroke engine, this is particularly true with kart engines, and they're often overlooked.
While there is no set in stone rule that dictates when they should be replaced, reading your plug should give you an indication on the performance of your engine, whether carby settings need adjusting or jets need changing or whether a plug in a different heat range would be better suited to the conditions.

Better spark, combined with the right amount of fuel/air equals power.

61motorsport are super excited to be able to offer Brisk Spark Plugs.

From the Czech Republic, Brisk are very popular in Europe and make fantastic products for high performance applications. Brisk Spark Plugs are excellent in karting applications too and are often the sole supplier of plugs for large international karting events. Plugs are available to suit all karting applications and we are slowly expanding the Brisk plugs we are able to offer.

In addition to Brisk, 61motorsport also offer both NGK and Denso spark plugs.

NGK are popular for most kart engines and Denso are extremely popular in Rotax classes and are often used as the 'control' spark plug for Rotax Pro Tour events.
