D&D Cycle Inc. is a small, low volume motorcycle shop with personal and friendly
service. Located conveniently off  Rt. 78 in San Marcos, CA.  
Our specialty is dyno tuning of American and Metric cruisers.  If any exhaust or intake
system components have been changed or  custom engine work done, most likely
your bike will need jetting or mapping.  Using our SuperFlow dynamometer with
Eddy current load control we can correct for proper air/fuel mixture.  Some of the
tuning devices we service are the Power Commander™ and the Screaming Eagle
Race Tuner™.  Some of the common carburetors we jet are Mikuni, S&S, and
Keihin.  Need more power or better fuel economy?  We can tune to your riding
needs.  Maintaining proper the air/fuel mixture will keep your ride safe and
environmentally clean.
We are also experienced in servicing and repair of late model Harley Davidson,
Yamaha, Suzuki, Kawasaki, and Honda cruisers.  Call or visit us if you have trouble
finding a shop to repair or service your older motorcycle or scooter.  If we can't do it,
we will find someone for you who can.

Safe Riding
