Dynojet Yamaha FJ1200 86-93 Stage 1,3 Intake Performance Jet Kit

Maximizes carburetor performance

Includes step-by-step instructions

Stage 1 Kits

• Intended for motorcycles with a stock engine using the stock air box, 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 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 air box designs, individual filters and proper jetting offer no performance improvement yet compromise driveability, in such cases stage 3 kits are not available
