Fit perfectly, nice looc and finish

Well designed and thought out. Good instructions as well.

Highly recommend

Great design and great idea. One of my 110s has been randomly noisy for a while and I know that chain chattering around is not a good thing. This fixed that instantly. I'll be ordering another one for my other 110 and one for my CT125.

Do exactly what they should !

We live CJR!

Worth every penny. Quick and seemles turn around.

CJR is the best in the business. Cameron’s knowledge and customer service is outstanding. My dirt bike rips after having Cameron tune the ECU and installing their stock bore stage 1 kit. Thank you CJR!!!

There is good reason many places will refer you to CJR for flashing services and parts. Cameron was super helpful and answered all my questions. I needed two CRF125’s flashed and back to me in a hurry!!! After speaking on the phone they were back in my hand three days later, and I’m on the west coast. I can’t say thank you enough Cameron for your help and expedited service, I will definitely do more business with you and send anyone I can your way 👍🏻

Got my ecu back and it’s night and day. Thing revs out super quick, response is much better, and the new rev limit brings it to another level

I love the change I’m excited to see how it holds up in a race..

Thing is awesome i got a 24m throttle and ecu with this and it lit it upp like night and day different i recommend getting this with a ecu!!

Nice bolt on product that gives you a little more power on the top end of the gear for sure. You will be able to pull hills at a higher speed. Go ahead and get a plug and play ECM to go with it and everything will work nicely.

First off the service and shipping was amazingly fast. But this bike is an absolute beast after the ECU flash and adding the throttle body, manifold, injector and bigger fuel line. I was absolutely blown away by the performance. I couldn’t be any happier. Thanks!!!

I have many 140-190cc Klx bikes. Nothing is faster than this crf Cameron built.

Had 2 stock bikes. Installed this kit and tune on one of them and it smokes the stock bike now. Pretty straightforward install. Just carefully put it together they way you took it apart.
