“Wow!
Haha, after my first 5 seconds I was in awe of your creation!
I’m such a anal YZ fan, it’s embarrassing, this has buzzed me all day whilst riding, I think this mod would of saved me a fortune had it been the first, also having said that it’s the final piece of the puzzle for my engine mods, it’s pieced it all together.
The product, the installation guidance, and the support have been second to none.
There is no YZ owner that doesn’t need this mod.”

"I must say, I was very impressed with the packaging. And your videos were extremely helpful with clearing up any questions I had.
-I was absolutely amazed at how smoothly the shaft rotates compared to the OE set up.
-It is unreal how much more smooth and efficient the power valve operates!
The violent hit was gone. Instead the power still came on strong but manageable and somehow continued to pull higher than OE before signing off.
-I was originally expecting the stiffer governor spring to “neuter” the iconic strong mid range of the YZ and just push the power valve to only operate at high rpm’s. The results were COMPLETELY not what I was expecting. The bottom and mid range were not neutered, they were actually enhanced.
-The power valve feels like it allows the engine to move the air more efficiently through a broader power band and impressively still pulls higher than OE.
-I was fully prepared for my bike to feel similar to a TPI bike. Smooth, almost electric power delivery with zero hit and leaving much to be desired down low. But instead I still have a bike with exciting mid range, but with smooth predictable power higher into the rev range.
I feel like this is how Yamaha should have engineered this engine to efficiently move air.
I’m very impressed with your product. Good work."

"I got your kit, which looks amazing by the way.
I went out this passed Sunday,
All I can say is wicked, @#$%@# wicked
The bike is now like how it’s supposed to be off the showroom floor.
Smooth, I could tell it runs off the engine governor now 100%
My bike is deadly, the final piece to my puzzle
This bike is an absolute killer
Thanks so much"

"So I regularly take part in time card events, total ride time is 4hours, you regularly race against the same individuals and I’ve commonly finished 2nd, 3rd or fourth, the special “test” you ride each lap and is a timed section, this would normally take about 6-8minutes ( you probably know all this) but anyway I started the first lap good and I found myself getting faster and faster, I thought about this on my way home, my thoughts throughout the race was just concentrating on form, weighting the pegs, body position and recording track details, I’ve not been able to do this on this bike before and I knew this is what I was missing, This is a result of Hitlis!
I no longer have to worry about the engine and what it’s doing, I know what it’s doing! It then becomes a subconscious Action.
The result was my first win in class, unbelievable! But it wasn’t a win it was a destruction, I belonged in another class! this one competitor who would always beat me, last time by only a second in the special test, this time I beat him by almost thirty seconds! This was within a 6 minute test, a serious improvement.
You mentioned going back to a higher compression head and this is the exact same thought I had on the way home, my other thought was how much better your clutch work becomes, it’s so much easier! Out of corners, going up hills and blipping to go over obstacles, Instead of getting 100% of the power you get 20,40,60,80,100%, it’s up to YOU! and it’s so easy to manage now!
I can’t wait to go out again this weekend, knowing I’ve got the bike that I’ve been piecing together and that I can now get the results with. It makes it all worth it, honestly! I was about to give up with it.
To say I’m thankful and impressed just wouldn’t be enough to do this product justice."

"Everything in the kit was well organized and in a plastic lure box. The machine work on the parts was first class. The installation was very straight forward.
After warming the bike up I did about 9 or 10 rips up and down my street. The abrupt hit is gone (hence the product name).
The bike is smoother and was definitely easier to ride in the single track. It just has a long, smooth pull. Not unlike a 4 stroke, but more lively. The bike also sounds different.
It's smoother but has just as much horse power as before. A big hit can make you think it has more power when it doesn’t. The abrupt hit will light up the back tire or pull the front wheel in the air. It also tires you out quicker.
The HITLIS puts more power to the ground. I was having so much fun that I ran it out of gas and was happy for the reserve.
Most of the aftermarket stuff you buy for a YZ makes it run the same or worse. This actually works."

"Firstly, amazing product! Great piece of engineering and much needed modification. I’ve watched the videos, they are great and fully detailed.
I’ve not long ago completed another yz 250 woods build, after owning 3 other yz 250s I built this one piecing the best bits I have done before into this bike but the power valve opening has been a hurdle that has yet to be fully solved, this has always caused grip issues whilst hill climbing and in muddy conditions.
I’ve had a smile from ear to ear ever since I let the clutch out today. It’s smooth, predictable and useable, gives a torquey feel throughout the build up and I love it! I find myself asking, is there any need for any of the other mods?
I can’t compliment Productive Power enough for this idea, service, and the communication is great."

"This HITLIS mod is top notch.
I spent tons of money on different mods but if I had the option long ago to the HITLIS I wouldn’t have bothered doing anything else other then just rip the trails etc.
Super happy, smiling and having a great ride, wanting it to not end!
I love how smooth and controllable the bike is now, it tractors so awesome, I love my YZ285X BB set up, she rips"

"The HITLIS is definitely not slow. It’s more connected to the ground without the violent wheelspin, each gear seemed to pull longer.
On my test loop, there is one hill that you have a hard left out of a ravine, then a loose rocky uphill with two stairsteps at the top. Until the HITLIS, I could not get enough drive up the hill to hit the first stair step and clear the second one. I could on my 4T. Now I can clear it on my YZ. Ha, no need to discuss how a 20 yr old YZ is competitive with a very expensive '22 "modern 4T”!
I increased the preload this past weekend. No power loss, you have an even more linear powerband, just keep twisting the throttle for more power. It felt like “traction control” and it pulls strong between corners. Whoops, it’s great. Able to stay on the gas and in control. Top speed improved, and heart rate went down substantially."

"I think all the bike magazines should do a review with this product! And expose it for what it is!
Words can’t even describe how good this makes the bike work, Tim with HITLIS wasn’t joking when he said this should be the first mod you do to the bike.
I’ve messed around with these Yamahas for a long time, and I consider my bike to have been pretty dialed for my style of riding/ trails, hills etc, But when I added the HITLIS Woods kit and rode it last Sunday, you couldn’t wipe the smile off my face literally.
With this set up now the governor controls the power valve and you can tell right away how smooth and controllable the power is. Don’t get me wrong it’s not weak, it’s far from that! The power is smooth, predictable, with a nice linear not abrupt spike in powerband.
Hats off to the HITLIS team. This product kicks a**!"

"I received my kit. Nice package and instructions.
The HITLIS pulls 2nd gear out of tight corners without any clutch work. After that the power is just so smooth and strong, it transitions to “on the pipe” and stays straight and connected to the ground. No rear end dancing and going everywhere fighting for control. I can be on the pipe in area 3 of a corner now, before it was area 4 or completely out of the corner. I'm staying in control and already set up and in position for the next corner. My tracks between corners was only about 1’ wide, in the past it was 3’ wide after a short session on this bike. So I’m more in control, similar to what I experience on a 4T, which is why for the last 8 years a 250F with a big bore kit has been my primary enduro bike. So far I'm thinking this is going to change that."
Let customers speak for us
from 72 reviewsThis is a great part. When riding a YZ, there are times when the rear traction is lost, but with Hitlis attached, the traction does not drop and the bike moves forward. The power does not decrease, but it becomes usable. They ship outside of the US, so if you are even slightly interested, you should buy it.

Ever bought something that kind of helps or makes a little difference? NOT with the Hitlis. There is no "placebo" effect with this product, it works! I installed this on my 2024 yz250x. The 250x definitely has a hit that causes lots of wheel spin. With the Hitlis, the bike puts power to the ground and moves you forward. Don't get me wrong, I can still spin the rear wheel if I want, the power is still there. It's just that the "hit" is gone. Less tiring to ride the bike? Yes. I read quite a bit about this product and the reviews. It almost sounded to good to be true. I'm glad to report the reviews are spot on. The only thing I found is the videos don't really do the Hitlis justice. If you get a chance to ride a bike with it, do it. Install instructions and videos were excellent. Best purchase I have made for this bike!

I bought a Hitlis woods kit for my Yz250x and it was a game changer, best mod I’ve ever made to any of my Yz’s and I’ve been riding Yamahas for 40 years!! Within a week I ordered another Hitlis for my Big bore Yz300, since I don’t do hard enduro , Tim suggested the Desert Kit, along with new jetting . The bike is an absolute beast now!! Smooth , yet more power all through the power band!! I also own 2 Ktm 300 fuel injected 23 model bikes, and to be honest they will probably stay in the garage this year because the Hitlis kit has made everything else obsolete, Tim also has the best customer service and support of any aftermarket company I have delt with!! I highly recommend if you have a Yz , do yourself a favor and order a Hitlis!!

Gave me way more confidence in riding. Power is so smooth and manageable. Revs like a 250 and lugs like a 300. I tell everyone on the trail with a yz about HITLIS

Hey Tim. I was able to get the HITLIS installed on my bike for two days ago, it was easy to install. I was watching your videos and follow your instructions. I was paying attention to the secondary linkages so they not was binding. I have tested it for two days, and I love it. This system has changed my entire experience of driving my Yamaha yz 250. As an enduro bike, I can not thank you enough for inventing and making this superb system. Mikael Andersson.

The Hitlis gives me the instant power I need from my 2009 yz285. It easily runs with my buddies that are all on current KTM 300’s.

So far great product, with awesome instructions for installing. I can not wait to take a spin on the bike, will update the review once I have been able to go for a ride.

This is the best modification I’ve ever done to any of my Yzs and I’ve been riding them since 1979, amazing power , smooth delivery and the best customer service I’ve ever had!! Tim is a very knowledgeable guy and actually takes the time to answer any questions! I liked the kit so much I just ordered another one for my second Yz !!

Amazing product for the Yamaha Yz250,
Excellent communication and customer service, great people and a high quality product made right here in the USA

This mod makes the bike much more controllable in tight single track here on the East coast. I have the standard woods setting, Apex XC head and jetted for my location. The bike is much easier to control in tight woods with small ruts and limited traction. It has stands up and still flys at WOT. This is easily the best mod I've done to make the bike a great woods bike.

Been riding my 2023 YZ250X for a year and always wondered how to make the power more manageable in certain situations and the hitlis system was the answer! I absolutely love how the bike performs now from 1st and 2nd lugging to 5th wide it is a better machine. This will be the first thing I do to any of my YZ's in the future.

I am 62 and race enduros,hare scrambles and sprint enduros. I ordered the woods kit for my bike. I own a 19 250X. I guess you would say I am a B+ rider. I can say that I enjoyed my X in stock form. It took some jetting to get it where it would continue you to keep pulling and not loose power when it was pulling a hard long hill. You would have a quick hit and then you do have to work the clutch to keep the momentum.
The HITLIS kit just smooths the motor from off idle to full throttle. It's ability to let the bike hook up in tight slick conditions makes the rear wheel hook up with very little spin. If it spins. Shift up. It will keep pulling.
I gave it the best test I could on a 30 mile loop last weekend. Tight,single track,frozen,off camber,hills you name it. I was really greatly impressed with the complete control and pull of the motor.
In this day and time where everything is so expensive, the HITLIS is definitely worth your money.
Have a great ride.

The way yamaha should of designed the power valve can be found here.
Superior design, rideability and build quality.
Quality packaging and instructions.

Perfect and surprising, the mounted in regime are well linear, the bike becomes more exploitable.
Adjust the valves according to the terrain.
Very good modification!
