Easy to follow installation instructions. This kit has turned my yz250X into the smoothest power I have ever felt on a YZ250. It eliminates the blast of power in the midrange and makes it smooth. It takes the same power and distributes it lower in the RPM and now my bike will gradually raise the front wheel because it is hooking up instead of spinning through the mid range. I also have a FWW, a DRT head, and I followed Tim's jetting recommendations and my bike is dialed with no adjustments needed.

Great product that drastically improves the controllability of your bike and phenomenal customer service!

After installing and understanding exactly how this product works I would have easily paid double the price to get the performance all X owners desire. Installation is straight forward. Take your time and don't hesitate to ask Tim questions. His service and communication is awesome and his knowledge on behalf of these bikes is greatly appreciated for an armature like myself. The HITLIS will not disappoint. My bike is street legal and prior to the HITLIS this thing was miserable putting around town. It's a completely different animal now.

When you get your HITLIS installed, be sure to let your KTM and HUSKY buddies try it out on the trail. The YZ is known for it's affordability, power and reliability. They just work, and with the HITLIS there's no reason to consider another bike.

Great product. Superb explanation videos, and easy to install.

Haven't installed the woods kit but the package was shipped so fast I thought it was a mistake and came with a personalized note in the kit and a Bible verse. Very well put together and greatly appreciate the effort put in to the package!
