Zipper's Performance is selling more than just the "next best thing". Instead, they focus on the customer's goals and work to provide the very best, most comprehensive performance solution. Additionally, I know the staff at Zipper's Performance is dedicated to my business because they know me. When I call in, I recognize the individual employees (most of who have been there for many years) and they know me. They support my growth efforts and help me use the resources Zipper's has available to expand.

I wanted to check in after riding the bike for a couple hundred miles. Took it to the beach last weekend. Now I know that there was in fact something missing with the bike. It just simply feels better, tighter. (because something was loose inside the motor) It is more fun to ride now.

Again thank you guys for taking it in and turning it around in 1 day. As you told me, you guys had an idea of what the problem might be, and were right. Had I listened to all the roadside mechanics, I would have been spending money on parts that were not bad.

I will be letting anyone who asks about getting their bikes fixed to give Zipper's a call before going anywhere else.

I acquired this bike from a friend who was quitting riding. After riding it I decided it was boring. With only 40hp is was really not that fun to ride. You had to wring the hell out of it to have any fun and it felt like it did not like that and was overstressed. I had Zippers do their magic. They installed the 1200cc Torkster kit. WOW. What an improvement. It is like a different bike. It is much smoother, power is everywhere. It does not matter if you are at 2000 rpm or 4000rpm it pull like a freight train. Not scary fast like a hot rod, not peaky or temperamental, just clean power everywhere. It double the HP and TQ over stock with no negative side effects. I have had faster bike, but none ran an smooth clean or were as enjoyable to just go out and ride.

My wife and I are in Meadows of Dan - MP 174.2 of the Blue Ridge Parkway. We have ridden about 650 miles so far - likely another 650 before we get home. You guys are the best. The new TMax on my wife's Fat Boy is working perfectly. Thanks for the adjustments. The performance upgrade on the Ultra Glide is outstanding - I don't mind downshifting, but I could get away without it. I love the kick I get any time I apply the throttle. Digging thru the Parkway at 45 to 50 in 4th is an absolute blast. Getting up to 60 takes about a second. If you know Luray, VA, you know when coming out of town there is a steep hill on 211 as you leave Uncle Buck's Restaurant. I inadvertently started off in 2nd - and just ate that hill up. Thanks everyone - you are a great team. Thanks Bob - you are a genius with your toolbox.

Just a line to thank you guys after purchasing your G2 Carb - I have been fighting a carb that had a ThunderJet and other things done to it. I even tried to straighten it out [by] jetting it, etc. Then I decided to buy a new G2 Zipper's Carb. WOW, seriously, this was the best investment to my bike with a (S&S) crate motor that I could have done. Right away the bike settled down - idle, cruising, and especially [at] the drag strip. It gained 4 tenths and 6mph the first 2 passes down the track. After slightly rejetting, I gained another 10th the next weekend [at] State Capitol Raceway, Baton Rouge, Louisiana. So thank you again for a great product!!

Waiting for Harley to do something good, finally I bought a 2014 Ultra Limited. Love the changes and handling but unsatisfied with the drive train. Based on past experience with the Zipper's Service, Support, and Products I decided to run the combination of a High Flow Air Kit, the ThunderMax, and a set of RCXHaust. Simple – Clean, woke the 103 right up. Before, the response was very unstable – issues with throttle response below 2000 RPM and always felt restricted on WOT. After – very responsive at any PRM, the 'Beach' (sand beige and brown) pulls hard thru top end. Thanks to Dan and his crew. Thru the years of HDRA racing and upgrading client rides they have continued to provide top notch product and service. And, for the few issues with tweaking the TMAX to a clients' bike, the TMAX Support team has been right on top of analyzing captured data and providing recommended processes.

 My son found this 2002 Ultra Classic for me on Craigslist... cheap. It needed repainting which will be done soon. Otherwise he was told by the original owner, who was a retired Certified HD mechanic… who did all his own work on this bike… that it was a 95 inch motor with a .510 S&S cam, etc. Long story short the seller was the fourth owner. He was never an HD mechanic and did not actually know what was in the bike.

While installing new cam chain tensioners, my mechanic discovered it has an Andrews cam similar to a .510, which he thought would have been bigger for a 95 inch. After new brakes, rotors, tires, tensioners and installation of the ThunderMax, there's still a lot we don't know about this bike. However, what we do know is this thing runs like a batt. Gobs of torque, very smooth... no pings or hiccups, great mileage, etc. We still don't know what's in this bike, but the ThunderMax does and that's all that matters. Great product. Well worth the money. HAPPY, HAPPY, HAPPY.

 “First, I know we are in an enthusiast-based business where clients want to spend hard earned money, but they want to spend it wisely. Only a small number of motorcycle shops acknowledge this. It is important to me to build strong relationships with my clients. I want to give my customers the best choice the first time, rather than just collecting cash. As a small shop owner, I work with the same clients or the same motorcycles all the time. I've been in business for over 30 years, and I've worked hard to earn my customer's trust and repeat business. I want to deliver a top of the line product that keeps them coming back.

Zipper's Performance Products shares the same philosophy. I know my business is important to them. Not only do I receive excellent sales service when dealing with Zipper's Performance, but I also receive personalized tech support. The staff at Zipper's is extremely knowledgeable and will go out of their way to help me, 24/7. Zipper's Performance is selling more than just the “next best thing”. Instead, they focus on the customer's goals and work to provide the very best, most comprehensive performance solution. Additionally, I know the staff at Zipper's Performance is dedicated to my business because they know me. When I call in, I recognize the individual employees (most of who have been there for many years) and they know me. They support my growth efforts and help me use the resources Zipper's has available to expand.

As a business owner, I know I am partnered with a successful, national company who treats my business uniquely and not as another account number. Zipper's Performance provides me with quite a few sales leads and, as far as I'm concerned, is here to stay in my shop. Important resources like tech support and training are always available (just ask!), with 24/7 sales support available by phone or email, and I am treated with the same one-on-one focus I give my customers. Even though I am a fairly small shop, I am here to stay and Zipper's values my business.“

 “I LOVE my ThunderMax TBW system. I have had it for 3-4 years and haven't touched it since the original install. I have recommended it to many people and the ones who have purchased ThunderMax's are delighted with the results. I keep close watch on my gauges, feel, and fuel mileage. I ride 1 and 2 up on short and long hauls. Usually, I am running above 45mpg and on the last, long haul through the mountains and roads from NJ to upper Vermont, I range between 47-50 mpg. Engine temps are a lot cooler now than before, too. Thank you for the super product!”

 “I have a 2010 FLHX what I've modified quite a bit. 106” S&S Big Bore Kit, Ported Heads, Welded & Trued S&S Flywheel, Fueling Oil Pump and Cam Plate, Free Flowing Air Cleaner, V&H Pro Pipes (2-into-1), several drivetrain upgrades, Red Shift 575 cams, and a ThunderMax ECM. I purchased Red Shift 575 cams to focus on torque, and it certainly has torque! The front wheel likes to get airborne, especially when riding 2-up. I've tweaked the tune to where I feel like I'm not leaving much on the table. My highway riding is great. I can roll on in 6th gear doing 95mph and still pull, but not for long. I can push it to 5k in 3rd, 4th, and 5th, and get up to 120ish in 6th. I'm an aggressive rider and I push my bike hard when I'm having fun. Most of my riding, though, is done at sane speeds within sight of the speed limit. Thanks for some great products!”
