Jet Kits

To get the horsepower built in to every Erion Racing Exhaust system (except the CBR900 slip-on muffler, which works fine alone) we recommend an Erion Racing carburetor jet kit. Developed on our dyno by Dynojet's master technicians, every jet kit is a perfect match for your Erion Racing exhaust system.

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.
