The hitlis is like unlocking a new mode on your yz250. When you first install it and cruise it around, you feel like you can feel something right away. But it’s not until you get it on the track or trail that you really notice the wow factor!! This thing creates a new bike! And the next couple times you ride it after that, the more you notice the difference. This has now made my yz250 my new favorite bike, it is so much more fun to ride! This will be the FIRST thing I put on my next yz250.

HITLIS transformed my YZ250x. The power is so manageable, but none was given up with the HITLIS kit. Purchased the woods kit and couldn't be happier. Tim has been incredible with supporting me during install and recommending really good jetting specs to accompany the new PV system.

I have a completely stock 2020 yz250x and this was the first performance mod I did to it. The change is night and day. I won’t bother explaining it, as everyone else already does a good job of that!

Tim was/is a huge help in make sure everything went smoothly on the install as well as helped with any random yz questions I had (I have a lot, as this was my first 2 stroke ever).He also gave me some great advice for tuning the carb even further to get the most out of the new Hitlis system. Needless to say, the product is a 10/10 and Tim’s excellent help and customer service made it an 11/10. Quality all around experience and product. You truly get what you pay for in this.

I came from riding big four-stroke bikes like the DR650. When I first got my YZ250X, it was harder to ride than I expected. I thought I just needed more practice, but then I kept hearing about this HITLIS mod. After thinking about it for a while, I decided to try it.

The install was easy. Tim, the guy who made it, even helped me over the phone while I was putting it on. I now have about five hours riding with the HITLIS, and my bike feels completely different. It’s exactly how I thought the YZ250X would feel when I bought it—smooth, fast, and fun. The power is easier to control, and I don’t get as tired as before.

I did wonder if I should have just learned to ride the stock bike, but after trying this, I don’t think I’ll ever go back. Now I can focus on becoming a better rider instead of fighting the bike. Next, I’ll be working on the jetting with Tim’s help, and I plan to add a YZ250 head and GYTR flywheel weight. After that, I don’t think I’ll change anything else. I’m just excited to enjoy this bike for years to come.

This mod was definitely worth it to me.

This product is honestly a game changer if you want to ride the YZ platform for challenging, technical riding.

I'm on a 24 YZ250x with a 24 YZ250 cylinder and ignition with a bunch of bolt on goodies.

In every situation I am now riding a gear higher and am considerably quicker in the hard stuff since installing HITLIS.

Bike pulls so hard straight off the bottom but always controllable. I spent a fair bit of time in 1st gear before but now in 2nd and sometimes 2 gears higher.

Deadset the best mod you could do for your YZ.

Awesome work Tim.
