2005 Honda CRF150f Top End Rebuild 

Thank you for this video. My grandson and I installed a new cylinder, piston, wrist pin and rings this morning. I set the valves as shown, cam lobes down after timing it and adjusting the chain tensioner. So much good useful information! I have a shop manual too, but the video shows it better. You did a good job.

Great detail here.

It would of been nice to see the order they go

Thank you so much for this very informative video, my 150 skipped time and bent a valve

What about the exhaust valve ? Mine is the exact same way but dosnt seem bent at all. Possibly just carbon build up ? Another RU-vid video I watched they are rebuilding a 230f top end. Same exact thing looks like it isn't seating all the way. Maybe it is just the way they are made. Mine is a 230f im doing by the way. But ya let me know what you think. And great in depth detailed video thanks !!

How bout the cheap top end kits i see. I know they’re not high performance would they work in a crf125 or would you just go oem. I don’t know if I need a cylinder head or not at all. It’s a 2020 and smoking on startup also while riding. Not visually. You can smell it , the oils getting dark fast and losing oil. Needs oil every few rides. I do oil every 15 hours ish. Few times a summer

Can you do a more in depth video i have a 125f the flywheel is similar jsut trying to figure out how to take the bolt off and put it back on with the fly wheel puller

How to put in the cam guides
