Master Spanner Spinner
TB 54mm jug & slug kit, direct bolt on for Chinese 86/107cc engines with 49.5 stroke and 69mm tall jug. Adds displacement, compression and HEAPS more midrange. Alloy jug saves some weight and cools better. Performance will be on par or better than the 125 crate engines, while being lighter and revvier. I've personally installed over a dozen of these, and never had an unhappy customer. Zoooom!
