Welcome to
Westchester Powersports online!

Thank you for visiting our brand-new, state-of-the-art home on the world wide web! Westchester Powersports is the only Dyno tuning center in Westchester and Putnam Counties, offering full Dyno tuning capabilities for all your powersport needs! We have the latest and greatest from the world-renowned  leader in horsepower extraction and custom fuel map engineering, Dynojet, including the all new 250ix Dynamometer. The 250ix is a dual-drum, load-control Dyno with an exhaust gas analyzer used for creating custom fuel maps. This machine has really set the powersports world ablaze recently, allowing for full custom fuel maps to be created for all ATVs, side x sides, go karts, and, yes, even trikes, as well as ALL motorcycles—whether they are street bikes or dirt bikes. Westchester Powersports opened in May of  2009, the brainchild of  John Narciso, former general manager and Dyno Master at one of the area's  largest and most well-known Harley-Davidson® dealerships. Since virtually every single new motorcycle and ATV that has gotten released worldwide by every manufacturer since 2007 is fuel injected, John saw the need for a full Dyno tuning center that specialized in one thing—maximizing and extracting the most horsepower and foot pounds of torque from fuel-injected motorcycles and ATVs without compromising their fuel mileage and rideability. With 11 years of in-dealership experience, John had heard one too many horror stories from friends and clients alike, about all these jack-of-all-trades, master-of-none shops, tuning people's machines, only to have their motorcycles run worse than they did before dropping them off!

John has been operating a Dynamometer since 1998, and he's been Dyno tuning since 2001. Creating custom fuel maps for race-ridden and -driven machines has been John's passion for quite some time, as is evidenced by his quick ascension from Dyno operator to race tuner to owning and operating his own state-of-the-art, eco-friendly Dyno tuning facility. And it doesn't stop there, as Westchester Powersports also offers all kinds of  in-house services devoted to making any client's experience as easy and headache-free as humanly possible! We do everything from scheduled maintenance, to tire and wheel swaps, to collision repair, full frame-off antique motorcycle restorations, full accessorization and customization, and Dynamometer diagnostics. NO JOB IS TOO BIG OR TOO SMALL! And always remember that no client is too big or too small, either, as we welcome all commercial and corporate accounts, as well as any municipalities regardless of state of origin!

As previously mentioned, Westchester Powersports is as state-of-the-art and eco-friendly as any shop you might see in this day and age. Being green is important here in this portion of the globe, as space in the Tri State area is extremely limited and also extremely precious, especially in beautiful Westchester County. Everything gets recycled here, including tires, batteries, plastics and plastic bottles, cardboard, and even the oil, making Westchester Powersports virtually land-fill free, and leaving almost NO carbon footprint! Even the all new Omegasonics Ultrasonic benchtop parts washer is solvent-free, using a combination of  hot water, soundwaves and vibration to clean those stubborn, gummed-up, and neglected carburaters, etc! We were so amazed by this new entirely green technology, that we'll be running before and after photos of our hardest to clean carbureters on the website in a few weeks with a full review and write up for the Omegasonics machine! It's going to BLOW your mind while it cleans your parts!
