I picked up a YZ project and wanted to try to build a medium enduro bike that wasn't just orange or orange adjacent like all my buddies. I previously rode a husky and was on a mission to make the stock YZ work but it was hard to find usable power when things got technical. Thumpertalk led me here and well, the HITLIS accomplished all my goals better than expected. Instead of describing the benefits to power delivery, traction benefits and decrease in fatigue like many others have, I’ll focus on the customer service. Tim is awesome. You can tell that he’s someone who not only believes in his product, but he genuinely wants to help people out. Tim made himself available at every opportunity just to make sure that my experience with his product was top notch. As a random customer off the internet, I was blown away with the support I received in addition to the massive performance gains. I’ll be recommending this kit to anyone who will listen.

I've only got a few rides on the woods kit and man is it smooth! I have an apex head with mx dome along with 8 oz ffw and it is amazingly smooth. I ride a mix of hard enduro and flowy singletrack. On the hard enduro stuff it's a game changer. On the flowy stuff a gear higher is nice. I do feel like I have to shift alot when things open up a bit to keep it in the power as the top end seems to be flat. Maybe I'll try the desert kit just to see or go back to stock pipe as I'm running a gnarly which is known to not have much top end. Overall I'm really impressed with how smooth the power is delivered. Mid range is absolutely amazing! Great product and easy install!

Brad here from Ontario Canada. I reached out to Tim at Hitlis about getting the power valve kit for my 23 Yz 250. I went with the desert kit as I ride motocross only never trail ride. Installation was fairly simple, Tim even talked to Me on phone to give Me a pointer on valve set-up. The bike works so good now, its very smooth with the Hitlis Desert Kit. Pulls hard but smooth right off bottom right through the entire Rpm! It even sounds better too. After riding it for a bit with the Desert Kit, Tim gave Me his suggested Carb Jetting specs for My bike. I wasn't sure if it would make a difference or not cause I thought it ran pretty dang good but after changing it to Tim's jetting specs, I am once again blown away with the difference in power at all rpm's with new jetting. Tim really knows how to turn these Yz250's into real Race machines! The throttle response is instantaneous and very crisp, pulls very smooth and just keeps building all the way to top end. I Highly Recommend the Hitlis Desert kit and Jetting Specs!

I’m defiantly going to make some bad habits of not using the clutch after this. It just climbs and climbs with no problem! Now to work on my speed coming back down after getting to the top!

Amazed how it can come back to life when putting around in second gear all the way down to idle then straight to life with a blip of the throttle.

Absolutely in love and can’t wait to put in the SX head and see even more power to be tamed.

Sosososo happy and thank you so much for putting in so much time and effort into this amazing piece of tech. Amazing tech and amazing support. You’re an absolute rock star. 10/10 from me.
