Installation Notes:  The kit does not work with the OEM original airbox.  Individual pod filters are required.  The air filter kit includes (2) pod style air filters and (2) K&N pod filter dirt socks (for k&N only).  The K&N filters are a little tight and may require bending them slightly between the two carbs for clearance.  A push/pull throttle assembly is very highly recommended but not mandatory.  The optional throttle assembly kit above will give you what is needed.  In addition the fuel tank requires spacing to raise up the rear end slightly to provide clearance for the throttle cable bracket.


This carburetor kit will seriously increase the performance of your bike.  The smaller bore sizes will provide maximum torque and throttle response.  The larger bores will produce superior power in the mid-range and top end at the sacrifice of torque and throttle response.  Go ahead and contact us with your specifications if you are unsure as to which size to go with.  Tuning and performance specs have been developed over the years to suit a wide variety of conditions, however some fine tuning may be required to attain the desired combination of performance, fuel mileage, and drivability.  Extra main and pilot jets are included for fine tuning and additional genuine Keihin parts and accessories are always available at low prices.  Alternatively kits can be built utilizing your own jetting specifications.
