TKM BT82 ENGINE
This is the engine that is used as the sole power source for the Formula TKM classes, the UK’s home-grown category that has been so successful. During its life it has been a market leader in the USA and winner of many World Endurance Championship titles.
The engine is of piston port air cooled design and specifically manufactured to provide ultra-reliability and consistency allowing drivers the maximum racing for their money. Many club drivers go 15-20 hours between rebuilds whereas the top championship contenders will do around 10-12 hrs between rebuilds.
Critical is the fact that virtually no modifications are permitted to the engine. And also, all parts fitted must be of approved and Tal-Ko specification and manufacture. Main components such as the liner are manufactured using computer aided machining to assure consistency. This ensures equal performance between each engine which holds costs at a sensible level.
Throughout the life of the BT82 there have been upgrades and additions to the engine to offer greater choice and make the engine stronger. However, performance has been held static so an early engine has virtually the same power as a recent one, though not the same strength. The engine is not sealed and can be serviced at the Tal-Ko Racing factory or by local dealers or even by the drivers/mechanics themselves.
The Inter, Junior and Senior Extreme engines are the same with simply a cylinder re-bore and cylinder head re-machine taking the engine from the Inter/Junior 100cc to the Senior 115cc. Thus, an engine can be used by a driver from 9 years right through to Senior. Carb air restrictor plates and exhaust restrictors are used to control power against weight within each class giving very close power to weight figures so drivers of every size and weight can all race together.
The engine is available in Direct Drive, Clutched and TAG (touch and go) format thereby offering the greatest choice of any kart engine in the world. Air cooling makes it easy and light to fit and maintain with no water pumps or radiators to worry about.
The EeziStart de-compression valve making starting of the engine much easier on the direct drive model. Cannot be used on TAG models as starter RPM speed is too low.
The Official TKM BT82 Engine Fiche is updated each year and gives the full specification of the engine together with details of minimal modifications permitted. It can be downloaded below along with the running guide and spare parts list.
