Here is our quick video of hours of work so far trying to repair CRF150R 2020. We got it damaged and hope to bring it back to life.
This is just engine rebuild/fixing. We have a lot to do still.
We are not professionals at all and are lucky to get this far.
Don’t judge 😊 please.
*********************
You ⚠️ MUST follow Honda 2007-2020 CRF150R Service Manual.
You have to also need to do your own research and homework as service manual is not easy to read.
We used several resources (forums, youtube.com and service manual) to progress through this project on our own.
You should replace all gaskets and seals that you disturb. In some cases you might need to replace them.
We got all our parts from motosport.com
20+ seals and gaskets, left crankcase and left crankcase cover.
Crankcase does come with smallest needle bearings but you still need to replace or reuse your other bearings. Pullers didn’t work. We used a heat gun and bearing driver kit to get the bearing out.
It is the same concept to remove bearings and then place them back in. Pain in the neck, however. That was the most difficult part of the project. The hot/cold trick did not work for us.
Second most difficult part is to be sure follow each step religiously including precise alignment of gears, torque requirements, etc.
You will need a torque tool or wrench, breaker bar, impact wrench, oils, grease, small 8mm wrench, etc
Feel free to reach out if you have any questions.
