Gave it some more bark for sure and a noticeable amount of power gain

Great product

Awesome as always

Great clutch. Much better feel than the stock unit

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!!
