As motorsports enthusiasts, for generations we have
been naturally drawn to the beauty of the gasoline engine!
Whether it be a motorcycle, race car, atv, or racing kart the
first thing we want to see is what is under the hood or in
between the frame rails!

DWMS Racing offers a full line of professional custom engine
building services and has a lifetime of racing experience and
custom engine crafting knowledge to share with you so whether
your needs are for a stock rebuild or a high performance racing
application you can feel comfortable putting your trust in us!

We rebuild most all two and four stroke motorcycle, atv, dirt bike,
jr. drag, and kart racing engines and we also restore most all
antique small engines as well! Whether you need one of our
singular services like carburetor rebuilding, porting and polishing,
cylinder head rebuilding, or a complete bare case engine build we
