Carburetor tuning kit Honda FMX 650 Dynojet Stage 2

Dynojet kits provide a simple solution to carburetion problems, increase power and improve delivery: based on pins with a different profile to the original, and equipped with other assorted material depending on the type of bike (jets, springs, air correctors, etc.).

• Stage 1 kits are intended for motorcycles with a stock engine using the stock airbox, air filter and stock pipe: Stage 1 kits are fully adjustable to allow the use of a well designed aftermarket pipes and stock replacement air filters like K&N. Stage 1 kits are designed to improve throttle response and driveability and in most cases power increases of approximately 5% throughout the entire power range can be achieved. Stage 2 kits are ntended 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.
• Stage 2 kits are 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 are 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.
