"Hi Folks
My name is Olaf Menzi and I’m living in Switzerland.
I’m riding a Pro Stock Buell in the European super twin top gas series. Last April, I visited the shop of DC V Twins and meet Derek Churchwell
What I meet there, is a center of master engine building competence.
Even after I arrived in the later afternoon, I helped Derek to bolt on a cylinder head of a Pro Mod Suzuki, and we were wrenching till 10.30 PM. So I could see how comprehensive his engine building skills are.
It was a great experience and I could see that those guys know what they're doing. That is very helpful for the trust in your team because drag racing is also a team sport.
I’m very thankful that I meet Derek face to face and it was quite an experience. So if you’re in the need to got more power in your v-twin!"
DC V-Twin is the ultimate address !!!
Regards from Switzerland,
Olaf

Hi Derek,
"Since it's been about a month now, I wanted to give you a report back on my 2000 Road King. You'll remember that I had a S&S VFI system installed to replace the OEM fuel injection and had a difficult time finding anyone with the knowledge and experience to properly tune my engine. While the bike was basically stock with an aftermarket exhaust and mild cams, I had just about given up and written off the VFI installation as a bad decision when I found you, and decided to give it one more try."
"In the last few weeks, I've been able to put about 1,000 miles on the bike. It's been ridden city streets around Atlanta, interstates, and a few hundred miles in the north Georgia mountains. So, I've had a chance to ride the bike in all sorts of conditions ranging from stop & go traffic, sustained highway speeds, and higher revving runs around the hills up north."
"Thus far, the engine has continued to run smoothly and freely across the rpm range. The torque it has at low RPM is far better than I had ever hoped, and the power builds smoothly as I run the rpm higher, all the way up to the redline. The engine cold starts much easier, and warm starts are no longer an issue. My gas mileage has also significantly improved from when I gave it to you."
"I couldn't ask for a better result. I appreciate the work you did for me."
Regards,
Ted Gradolf

“I’ve known Derek for over 10 years now and can’t say enough about his professionalism and passion for motorcycles. Since the early 2000’s Derek has been extremely involved in building awesome race motors for me as well as great street motors for some of my V-Twin customers. There hasn’t been a time when he didn’t make himself available for a few minute technical phone call an that goes a long way in this industry.” MICHAEL RAY - NHRA PRO STOCK BIKE RIDER & MULTI TIME AHDRA CHAMPION

Hello Derek,
"Just wanted to thank you again for all of your efforts to design and build the perfect 126” touring engine for my bike. With 160 HP and 157 FT pounds of torque I can now ride the Rocky Mountains without continuously shifting gears. The engine will run all day on the back roads and never climb over 180 degrees: at 80 to 90 on the interstate it will ease up to 225 on warm days, unbelievable and that is with no oil cooler. Fuel mileage is the same as my friends stock bike when riding under normal conditions. Other touring it will definitely blow the back tire off at the red light. The old bagger is a real sleeper and lots of fun looking at all the long faces when they pull up at the next red light. I just love it…..”Any Way you Won’t It” Keep up the good work my friend."

“All of the serious engine builders are at PRI, and one of the best is Derek Churchwell from DC V-TWIN.
It’s always great to see Derek. He and KPMI have a relationship that spans over two decades.
During that span of time, Derek has been intimately involved in more professional motorcycle drag racing championships than most folks will see in a lifetime.
He’s a knowledgeable, trusted, business partner, his feedback is invaluable, and he’s pleasure to work with”.

Not only does he build race winning engines, he has a vast knowledge of the parts that make up those engines. He's the guy for any custom motorcycle engine build."
