If youre an adult that rides the pitbike, you need to upgrade the power! Worth every dollar! Stage 2 plus is perfect!

Ecu sent got lost but they helped fix it.

Crazy power difference definitely worth it if you’re on the edge of buying it. I even had some trouble with usps shipping my Ecu there, and reached out and they were happy to help get me set up with a new one and back riding

Works great so far

Installation was easy. I love the fact that you don't have to disassemble This product to add the gear. As it is a complete package.

Bike runs great. as always it feels a lil sketch sending out your ecu but they provide tracking and the ecu comes back ina better box then I sent 😂

Quick shipping. bike runs great now!

If you do any mods to your bike like even adding an exhaust or the air box mod, you're going to make the bike not run right and risk problems. Now you either need to put it all back to stock or find a way to safely adjust everything based off exactly each item you did. This is where CJR tunes come in. They don't just crank everything to the max but every tune is individually taylored to what you did to your bike. Plus the support is awesome if you have any questions they get back to you right away. I just got my ecu back and it's running like a dream and feel good knowing my air fuel ratio is back in spec. Best 100 bucks you can spend on the bike for the performance and piece of mind knowing it's essentially like the factory again but with more power.

Great product

Really love the product, highly recommend!!!!! Service and quality is top shelf!!!!! 🤙🏾

Love how Cameron is so nice, and answers all my questions!

This thing is absolutely incredible. Not only does it make it sound sooo much better than stock, but it actually made a slightly noticeable power difference on my 110. The sound level is perfect, and it makes it much deeper. I didnt really notice a power difference until i put the stock baffle back on for a night ride and i could immediately tell it had a little less torque.

Haven’t used iit yet fast shipping

This is exactly what i was looking for, i had a nosiey cam chain on cold starts because it was loose and the auto adjuster was not doing its job put this in and problem went away.. installed 7 months ago!
