DYNOMAN PERFORMANCE - Motorcycle Performance Parts

Keihin CR Special Carburetors are an excellent upgrade for maximum performance.

CRs give superior performance for stock and modified engines,
if used with FREE FLOWING EXHAUST and HOT IGNITION.

FOR BEST RESULTS & PERFORMANCE

The magic combination for bolt-on horsepower is a great fuel delivery system, combined with high energy ignition, and free flowing exhaust system.

In keeping with that proven theory, we recommend the following:

Performance exhaust system such as Kerker with a competition Baffle
Electronic ignition system - Dyna 2000 or Dyna S with Dyna Coils

Keihin CRs come with Velocity Stacks for racing use.
For maximum engine protection, we recommend DP or K&N Air Filters

To help dial in your new carburetors for your specific engine requirements, we also recommend purchasing one size larger and one size smaller main jet sets. Available at a reduced price when purchased with carburetors.

To prevent air leaks, new intake manifolds (rubber carb boots) are recommended. Especially important if yours are old and hard.

ALL CR CARBURETORS MUST BE USED WITH PUSH/PULL TYPE THROTTLE

NOTE: Racing carburetors are legal in California only for racing (off road) vehicles,
and which will never be used on the highway.

NOTE:
For the 1977-78 CB750 application, the CR carburetors will work with your stock throttle and cables. However, you will need to shorten one of your cables. Unfortunately there is no cable available that is a bolt on, but we will send a "clamp on" cable end that will work with your stock cable. So installation will be simple. The cable end may also be soldered on as well, if you prefer.
