Mikuni's HSR42, HSR45 and HSR48
carburetors are the finest motorcycle carburetors made today.
They give superb throttle response and deliver all the air flow
needed for any level of Harley performance.
Twin Cam Performance:
The simple addition of an HSR42
"Easy Kit" together with high flow air cleaner and
exhaust modifications can increase power by 25%. Here is a typical
80.7 ft./lbs Torque
The Easy Kit dramatically improves the power of the H-D Twin
Cam engine and delivers unmatched throttle response and acceleration!
Maximum horsepower is typically increased from 58-60 to 72-75
HP, and Max torque from 71-73 to 81-85 ft/lbs. This example "before
and after" power increase was produced with the combination
of the Mikuni HSR42, a Screamin' Eagle Air Filter and a set of
(loud) Screamin' Eagle mufflers.
Polished HSR series carburetors
(42, 45 and 48mm) are available for the custom builder. Mikuni
takes special care to insure that the polishing is of the highest
quality. The polished HSR42 and 45 carburetors are not available
in kits and must be purchased separately. The HSR48 is only available
in kit form, plain or polished, which do include a choke cable.
Many dealers routinely exchange the standard for a polished and
chromed version in kits they sell.
