It was so helpful helping me do this cvo 103 build hard matching up parts. Zippers are awesome. The bike goes unreal took a 110 screamin eagle camed up so very happy. You wont go wrong dealing with zippers. Thanks Bill W.

I have been a customer of Zipper's since the 90's. They back cut my transmission gears to shift like a dream. We installed a Zipper's S&S Super 'D' Carburetor with 3 Thunder-Jets. In 1997 my stock 80 cubic inch Harley registered 120 horsepower to the rear wheel in open competition at the AMI Brute Horsepower Shootout in Daytona Beach during Bike Week to win First Place. I have called on Zipper's for performance advice and parts many times. I have both faith and confidence in Zipper's Performance.

I have done multiple performance upgrades from intake to exhaust and parts in between, but this cam, Red Shift 468,  was the single-most awesome performance upgrade I have ever made. Some upgrades are just noticeable on the dyno numbers, but this upgrade is beyond noticeable as a rider in the seat. If you are thinking about an investment to increase performance, I would pull the trigger on this one today!

Had issues with using a belt drive system. Decided to use a chain. I called Zippers and spoke with Pete Stewart. He helped me work through my ignorance and get it right. I now have a completed project with a Zippers chain kit! Thanks Pete for your great customer service.😎 Mike in Alaska

Just had Ricky's Custom Cycles install a 103 Muscle kit in my stock 96 cu Street Glide & man what a real kick in the pants now. Put the 103 Muscle kit, Stage III ported heads, S/S crank/rod combo, & a D&D Big Mouth Exhaust System. Holy Smokes is this bike FUN now! With the Thundermax tune along with these Dyno matched components, my scooter is Bad Ass Now. Love the sound at idle & going thru the gears. Two Thumbs Up to Zippers for a well thought out kit & to Ricky Stewart on a First Class Job! I recommend upgrading the clutch assembly to an after market like the Bandit Sportsman to complement the all new performance. You will not be disappointed. Billy "EVO" Schuh

I am an avid SPORTSMAN performance enthusiast . Just wanted to say I purchased a Zippers Muscle 128 kit and so far have logged 8k miles on the motor. The engine runs great and I have to say the way is designed its truly one the best kit I've purchased!

Looking forward to my next project with Zipper's.

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.
