Sam Evans started riding
motorcycles in 1972. He got his first Harley, a used 1973 XLCH
kick start Sportster in 1973 and never looked back.
He was constantly changing things on his bike to make it look
cooler or mostly to make it go faster.
In 1984 while racing his 111 cubic inch Shovelhead rigid frame in Gainesville,
Florida he met a man that would influence his life's direction.
The late Jim Simpson of Simpson Speed Specialties from Stroudsburg,
PA. Jim was the hottest thing going at the time at the track
with his modified S&S Super "D" Carbs and his unique looking
velocity stacks he made for them.
He was also an extremely
talented cylinder head porter.
After having Jim port his heads, Sam was astounded by the horsepower
increase and was convinced he needed to learn this craft.
After Sam set up his shop
for porting heads he spent a month in Pennsylvania with Jim working
7 days a week learning everything he could.
Sam's Performance
Specialties opened its doors in June, 1986 doing nothing but
porting, polishing and flow testing cylinder heads for the first
three years.
After hiring a factory
trained mechanic to do his valve jobs so he could have more time for
porting and port shape development, the natural progression was to
find a big building and start a full fledged motorcycle repair shop.
That was more than 25
years ago, and Sam is still making Harleys haul ass, building
dependable big-horsepower engines that run on pump gas and giving many
years of reliable service.
Sam has sent his work as
far away as Australia, Germany, France, England, Canada and all over
the USA from Alaska to Florida.
If you have a cylinder
head question or problem, Sam will usually have an answer and a solution
for you!
