Dynojet 2143 Jet Kit Stage 1 and 2 Maximizes carburetor performance. Two different kits to ensure you receive the amount of performance you require. Includes step-by-step instructions. Stage 1 Kits Intended for motorcycles with a stock engine using the stock airbox, air filter and stock pipe Fully adjustable to allow the use of well-designed aftermarket pipes and stock replacement air filters like K&N Designed to improve throttle response and driveability In most cases power increases of approximately 5% throughout the entire power range can be achieved Stage 2 Kits Intended for motorcycles with a stock or mildly tuned engine using a well designed aftermarket pipe with a modified airbox and a stock replacement air filter Designed for applications where individual filters cannot be installed and for applications where airbox modification improves the engine's performance In most cases power increases of approximately 8% can be achieved Stage 3 Kits Intended for motorcycles with stock or mildly tuned engines using a well-designed aftermarket pipe and individual air filters In most cases power increases of 10-15% can be achieved; however, driveability may be compromised particularly with short-stroke, high-rpm motors On some modern engine and airbox designs, individual filters and proper jetting offer no performance improvement yet compromise driveability; in such cases stage 3 kits are not available Stage 7 Kits Intended for race only use or for special applications, like the Yamaha V Max complete induction kit Designed to optimize jetting for a given tuning specification or racing conditions
