GSX-R750 88-89 RACE JET KIT
For the best top-end power (+2-3 True HP). Good low-end and midrange. Requires removal of stock airbox and running BMC xxxx or K&N equivalent individual air filters. Otherwise, it is a drop-in kit.
Note! When replacing a dj kit with Factory Pro components, be sure to replace the emulsion tubes with stock, Suzuki tubes (available from Suzuki). The dynojet emulsion tubes will not work with standard needles. The Mikuni emulsion tubes have ID numbers and the dynojet tubes are not marked with any part number.
