"As soon as I put the Dial-A-Jet on my machine, the throttle response was great. It made altitude compensation easy. I gained power instantly!"

"Dial-A-Jet is a really great product. We are a small dealer and sold over 50 Dial-A-Jet kits with no problems (if it snowed, we'd have doubled that)."

"The Dial-A-Jet, UFO, Nology Hotwires and TPI Valve products are unbelievable for the performance. It got rid of all the problems the sled had from the factory. Easy install; night and day difference."

"The Dial-A-Jet does what it says and a lot more."

"I took out my Brand X jet kit and installed Dial-A-Jet. My holeshot is great now! The Dial-A-Jet made a night and day difference."

"The Dial-A-Jets made my Banshee feel like it's fuel injected. Man, I can punch the throttle anytime and it's gone! I can also ride different areas without rejetting."

"The Dial-A-Jet works great on any quad. You can ride from Mexico to Flagstaff and run at peak horsepower without rejetting."

"Dial-A-Jet is an awesome product. Throttle response is unbelievable and its easy to rejet."

"Our family of four each have Polaris snow machines. My son and I are tuning advocates. We installed Dial-A-Jets in two of the machines and operated them in the Fairbanks, AK area. It is a rare pleasure to have a machine that runs well throughout the Fairbanks area. We like what the Dial-A-Jets do for our machines!"

"I will never jet another carburetor again after trying Dial-A-Jet. I love the DJ system. Man, what a difference."

"The Dial-A-Jet and HotWire made an unbelievable difference. My bike starts quicker and definitely has more power. Throttle response is off the map! I highly recommend these products."

"I just followed the simple directions for installation. We rode in New Mexico, Colorado, Wyoming and Utah reaching altitudes as high as 12,000 '. The Dial-A-jet worked great! I had all the power I wanted all the time. I would highly recommend this product to anyone with a carbureted engine."

"The Dial-A-Jet made a night and day difference in my 750 Brut Force. Even with my big tires I have plenty of power in high range. It has more horsepower everywhere."

"I LOVE this product (since 1995). It took my sled to a whole new level."

"Every Outlaw Engine that comes out of Whaley Motorsports has a Dial-A-Jet on it. No Outlaw race has ever been won without a Dial-A-Jet equipped carburetor."

I thought when I first got the Dial-a-jet it was sort of a joke. WAS I EVER WRONG! I put this on my 2012 Yamaha Grizzly 450 and man what a difference. The only thing I had done to my quad was put on a K&N air cleaner and when riding in Wallace, Idaho I would use more gas and it did not run as well as it should. My top speed was about 50 on flat ground with a good tail wind, after I put on the Dial-a-jet and rejetted the carb I could get up to almost 60 on that same flat ground and my MPG picked up as well. When you punch the throttle there is no hesitation, it is just get up and go. It feels like the engine is making more power. Best thing I have bought for my 4X4. One thing I have learned is that you need to stick with the original gas cap. I had a Tusk aluminum gas cap on and the vent on the cap is one way, (lets air in) but won't vent out. On hot days or the heat of the engine heating up the gas in the tank there was no place for the pressure to go so it would force the gas out up thru the dial-a-jet and flood the engine. Once to got it going again it ran fine. You need a cap that breaths both ways. If you want more power, better MPG, and no hesitation get the Dial-a-jet, you won't go wrong.

"I have spent a lot of money for more HP for my snowmobiles. It is pleasing to know that there are some products out there that do give you that extra HP at a very reasonable cost. I have tried and still use on all my Lake Race motors and High Performance trail motors, “Dial-a-Jets”. It is the best bang of HP on the market today. It seems harder to find Manufactures/Dealers that actually know how the product works and is willing to explain it to you. Lonn, at Thunder Products is one of those individuals. Every time I have called, he has always had the answers I was looking for. Along with other questions I haven’t asked yet. It’s nice to hear honest knowledge on the other end of the phone. Keep it up Lonn."

"I am very happy with my Dial-A-Jet. My engine pulls hard all the time no matter where I am and I never have to mess with my jets anymore."

"I gained 10 more mpg on my new motorcycle with the Dial-A-Jet and it had more response all the way around. It now runs like a 750."

"We are very happy with our Dial-A-Jets and TPI Valves. We ride from 300' to 11,000'."

"I am very pleased with your Dial-A-Jet. It fixed problems that nothing else would fix."

"I'm totally pleased and amazed with the results (Dial-A-Jet and UFO)."

"I have had a KLR650 Kawasaki, and XT550 Yamaha and a TT500 Yamaha with a Dial-A-Jet. It is the easiest way to take the mystery out of carburetor tuning. I have worked with carb tuning for many years and Dial-A-Jet has solved all my problems. I love the low end throttle response. My fuel mileage on my KLR went from consistent 47 mpg to 52 mpg." "I am installing Dial-A-Jets on my TDM Yamaha because of my previous success with the product. My 1995 Triumph Trophy 1200 was the most impressive in my mind. I installed a Daytona cam, K&N low restriction air filter and opened up the exhaust pipes. I installed the Dial-A-Jets and had it running absolutely perfect in a little less than one hour. Great product!"

"Throttle response is outrageous. I can pick the front wheels up in 2nd gear with the throttle. Dial-A-Jet is an awesome product."

"There's a night and day difference since I put Dial-A-Jets and UFO's on my sled. My biggest problem now is traction."

"It's so easy to make fine tuning adjustments!"

"We run Dial-A-Jets on Blaster and Banshee 4 wheelers. It's unbelievable what a difference they make! We sand drag our machines and they run great everywhere regardless of temperature or altitude."

"We use Dial-A-Jets on all of our world record holders as well as out personal street bikes."

"Dial-A-Jet solved all my carburetor problems with my aftermarket carburetor. The scooter now runs great!"

"I am writing you this letter to tell you how happy I am with your Dial-A-Jet product. I didn't think it would work as well as it does, but now I will install it on every machine I buy. By the way, my mileage went up 30%. Thanks again."

"I have installed Dial-A-Jets on 5 different machines and every one of them had more power and got better fuel mileage. The best part is they all ran great at any altitude or temperature without rejetting."

"I bought my 700 Ski-doo brand new in 2002 and was never happy with the performance and reliability of the DPM (digital performance management) carburetion. Unreliable and frustrating were the words I used to describe it. Rather than sell the sled I removed the DPM system and replaced it with a pair of swap meet 40 mm Mikuni round slides. Wanting the performance of the flat slide carb I added dual Dial-A-Jets and U.F.O.'s from Thunder Products along with their Thunder Shift kit. What a ride. 7000 miles later I still hear from my buds, "what have you done to that thing" My hole shot is great, mileage is 13/15, and she pulls like a freight train between corners. Thanks Lonn Peterson and all the folks at Thunder products for the support after the sale."

"Dial-A-Jet has substantially improved throttle response and power on all my bikes as well as made altitude adjustments very easy."

"I am extremely pleased and would recommend Dial-A-Jet to everyone."

I have a 500 Polaris Sportsman that would never run good at altitude of 10,000 to 11,000 ft. I installed a Dial-A-Jet and now it runs like a scalded dog at 11,000 ft and also runs great in Texas where I live at 1,100 ft. What a bargain for under $100!

"Dial-A-Jet works perfectly for altitude changes. It helped my ATV a lot."

"My sled was a dog, now it runs great!"

"Dial-A-Jet brought it all together and made it run at 110%. I can also ride at different altitudes without changing jets."

"With the Dial-A-Jet installed on the 125 KTM, it's as fast as the 144 KTM and is easier to ride due to the improved powerband. We plan to install a Dial-A-Jet on the 144 next."

The IntelaJet and Torque Wings really woke up my Yamaha SRX 700 Mountain Max all the way across the powerband!

I wanted to report on my two Harley Davidsons equipped with Torque Wings and IntelaJets. One bike is a 1200 and the other is a 1650. Both bikes run smoother with better throttle response. Also noted is the "correct" fuel curve as shown on my AFR meters. The IntelaJet works as advertised to maintain the correct fuel curve in low or high vacuum operation.

Hey guys - think outside the box a little. These products really work! My 120" Harley gained 11 ft/lbs of Torque n low and mid-range. It now does power wheelies and the fuel mileage actually improved. I would recommend the IntelaJet and Torque Wing to any Harley owner with a carbureted engine.

I have used Lectrons, Smart Carbs and others. Nothing even comes close to my factory carb on my 2013 KTM 250 SX with a Torque Wing, IntelaJet and bore job by Dick's Racing. My bike runs faster and smoother and gets better mileage than any other set up I've tried.

"Every now and then a new product comes along with the potential to be a "must-have" item in every snowmobile where it will fit. We strongly suspect this may be the case with the Ultimate Flow optimizer (UFO). The end result was simply awesome. The UFO was probably the most significant new product release of the year!"

"UFO and Thunder Shift Kit. This sled rocked with these in!"

"UFO's gave me a very noticeable increase in low and midrange power. I can also pull higher gearing than before."

"The throttle response and power increase from a set of UFOs is unreal!"

"The UFO's dramatically improved bottom end throttle response and made my Bull more than competitive with CR250 Hondas. I won my class (250 Sportsman Novice Western Regional) thanks to the UFO."

"UFO's are the biggest bang for the buck that you can put in your sled."

"If they say UFOs don't work, they've never experienced them."

"I'm totally pleased and amazed with the results (Dial-A-Jet and UFO)."

"Installed UFOs in carbs, absolutely incredible performance."

The Torque Wings are an awesome product. They do all that they say and more. From hole shot to wide-open throttle, the seat of the pants test will speak for itself. I wouldn't have a carbureted sled without them.

I just wanted to drop you a quick note and tell you the carb Dick Wilkes set up with the oval bore, Torque wing and IntelaJet rocked me back on my heals! My 2012 KTM 300 is stock an excellent bike, so good in fact, that I was reluctant to modify it. I worked at Dirt Bike and Motocross Action for 30 years, and I have to honestly say, not everything that I had a chance to test was an improvement. Not so with my modified carb....every aspect of the power delivery was improved. The bike is just as easy to ride at low RPM, but has more controllable power at every point in the powerband, and can be ridden a gear higher almost everywhere. What that doesn't tell you is.....this bike is now really fast! I have never added any two-stroke modification that made such a significant difference in a motorcycle in forty five years of riding. Thank you Lonn!

Boy, those Quad Flow Torque Wings really work slick. Low and mid0range power is awesome. My erratic idle is completely gone.

I installed the UFO and Torque Wing onto a Polaris 250 2 stroke Trail Boss. Wow! It sure smoothed up the bottom end and so much more responsive. I have some fine tuning to do but I sure am impressed with how it ran so far!! Thanks for all you do!!!

Well, we finally have snow and I have been able to test the Thunder Products torque wings in the SRX 700. The low-end throttle response is most definitely better from idle to half throttle is remarkably noticeable. Very responsive and comes alive right now! Would recommend to anyone looking for better low-end response, coming off the corners is bad ass! - Tom Graway—Totally Yamaha

The Quad Flow Torque Wing is amazing. The response feels like fuel injection with lots of torque!

The torque wings on my SRX triple definitely help on the bottom end response. Most noticeable idle to 1/2 or 3/4 throttle. Comes off the corners right now and crisp torque!  Just wanted to give you an update

The Torque Wing does everything it was advertised to do on my 144cc 2005 YZ125. It really cleaned up the low and mid-range performance and made the power seamless.

The IntelaJet and Torque Wings really woke up my Yamaha SRX 700 Mountain Max all the way across the power band!

I purchased a Thunder Products Torque Wing for my 1200 Harley Davidson running an HSR Mikuni carburetor. WOW, what a difference! There is a big increase in roll on power in low and mid-range. The power is smoother and better everywhere with crisp throttle response. It was well worth the money!

Just wanted to send you some updated photos of the install on my 08 Summit 800r. You can see where I tapped into the float bowls and how I installed the performance jets around my air box shroud. Everything worked out just right even with the limited amount of space I was dealing with. Finally got this sled dialed in and let me tell ya this thing pulls hard!! Thankfully we still have a few more weeks of riding up here in Alaska. Thank you again for all the help I really appreciate it and I’m sure you’ll be hearing from me in the future to get another set of those performance jets for my other 800 summit. Have a good day.

The Thunder PowerJet was so easy to tune. It worked precisely how we wanted. We were able to dial up the exact air fuel ratio we wanted.

"I installed UFO's and Thunder PowerJets and went from mild to wild - an absolute night and day difference and my fuel mileage actually improved."

"Thank you for providing us the opportunity to evaluate your TPI Valves. We installed a set into a 2002 Yamaha SXViper. The airbox is quite often restrictive, resulting in reduced performance. By installing a set of TPI Valves into an airbox, the airflow characteristics can be better matched to the carburetion settings. Our machine produced 116.8 HP with stock jetting and TPI Valves closed. After opening the TPI Valves the SXViper produced 119 HP, reflecting the increase in airflow to better match the fuel flow settings of the carburetors. We believe this simple test demonstrates typical results an average user would experience in real-world applications."

"I am really amazed at the increase in fuel mileage. The midrange and top end power also improved greatly. The Injector Perfector is a huge benefit for such a small amount of money."
