Guys, forget your fancy pipes, billet heads and super carbs! (I fell for it). HITLIS with Tim's jetting is the best improvement you can get. The low to mid it adds is incredible! If you're thinking this neuters your YZ at all you're wrong. Still has incredible top end with more over rev than stock. Add the best customer service i have had in years, this is a no brainer. ORDER NOW.
Has made my 2003 yz250 feel unbelievably linear and not in a boring way, instructions were super clear and support from tim has been top notch. Cannot recommend more!
What a difference it made, very smooth transition in power valve opening.
Great support and install videos. This is probably the best mod for the yz250
Ordering was very easy online and customer service was amazing and beyond extremely helpful, it was so nice to have a company do a follow up. The hitlis kit was easy to install and works amazing, so happy with our purchase and was a pleasure to deal with. Thank you!
