“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."

If you want to turn your YZ250 or YZ250X into a budget KTM slayer this is the first step.

I actually did a video on this product and I really wish this would have been around when I first had the YZ250: https://www.youtube.com/watch?v=vNxSZa9Fmx4&t=1s

The hit on the YZ turns into controllable pull from bottom to top, you don't really lose anything on top you just get there in a more predictable fashion. The bike doesn't become more 4 stroke like it's more of a feeling like a mix between the power curve of a TPI and a TBI KTM.

The installation is fairly easy and the install videos cover every conceivable encounter you may face installing the product. Also the support and insight from the developer along with their interest in following up with users of the Hitlis system is refreshing as it is helpful.

I would put this improvement as one of the most dramatic changes you can do to your bike off the bat and highly recommend it.
