In the spirit of life-long learning; the thing you are calling a "cylinder head" (@0:32) is the "cylinder". The thing that bolts to the top of the cylinder (which holds the valves) is a "cylinder head" (or just "head") (I think you may have called the head, a "valve cover" in a previous video). The part that bolts on top of the head is the "cam cover". BTW, you could have gotten this engine running perfectly and saved yourself a lot of money. A quick clean-up and lapping of the valves; running a simple cylinder hone up and down the bore a few times (to break the glaze); check ring end-gaps and bolt it all back together. 16,000 miles is not a lot for these engines; DRZ's have been known to go well over 62,000 miles (100 Kilometers) with nothing but routine maintenance (i.e. regular oil/filter changes, occasionally check the valves, and a new spark plug). Another pro tip; it's best to set the valves on the loose end of the tolerance after a rebuild; in an overhead cam engine like this, the valves are more likely to get tighter over time (tight valves will do far more damage to an engine than loose valves).
Appreciate the feedback and you watching the video! Good to know tips for future rebuilds always open to suggestions and feedback from other fellow riders. I like the tips about the values and correct terms. Sometimes when recording videos you get caught in the moment and mispronounce terms so thank you for calling this out its good for other folks watching. The only comment I might add is about the cylinder hone. I believe the drz400 uses Nikasil plated so from what I was told you cannot hone these. That's why kits are sold. Have you heard of something different with these bikes? I don't want folks to get confused thinking they are able to hone the cylinder. Let me know your thoughts. Again appreciate you watching my drz journey. - Scout 🙏
@@scouts_garage With this particular bike (with only 16,000 miles), I wouldn't even bother honing the cylinder. If I were doing a rebuild at over 60,000 miles, I might do a very light honing (e.g. 2-3 up/down passes at very low RPM on the drill), just to break the glaze. Nikasil is a very hard material (probably as hard as the honing stones), so I would have no issue with a light honing. FYI: I'm 67 years old; I've been motorcycling for over 50 years; I rebuilt my first engine 55 years ago - my father was an automotive engineer and purchased an old air-cooled Beetle for me to develop my mechanical skills (I learned to drive on that Beetle). My first motorcycle was a Honda CL350 that was crashed and pieces. I paid $25, and brought it home in a bunch of plastic milk crates (inside the VW - I had to remove the passenger seat to get the frame inside the car)! I had the bike running within 2 weeks. That CL350 looked so good when I was done, that the previous owner thought I had given up on the rebuild and purchased a new one from the dealership (until I showed him the VIN stamped on the frame). Keep up the good work!
good video thanks , But you could have done a detailed longer video so newbies like me can understand well. you didnt show even how to put the rings on the piston. you just explained
@ravi3457 appreciate you watching the videos. Check out my Drz400 playlist. I have a video on how to put on the rings. Hope it helps. God bless 🙌 🙏-Scout
Is there a reason your cylinder doesn't have a sleeve ? What ever happened with the crappy tolerance specs on these works cylinders ? Did they ever fix that problem ?
@@scouts_garage Yes, I have a 2022 KTM 690 enduro, but I want a second bike thats better suited for getting trashed offroad =D DRZ 400 is top of the wishlist.

@@scouts_garage thanks man..of course we like to see you fixing stuff.
After alll that you cold have installed a larger piston/ cylinder and cam system.
Whats going on with this bike now? Made progress recently?
Hey. Appreciate you watching close to being complete. Will release a video on after its all done. Right now waiting on some parts.
-Scout 🙏
how many miles did the bike do before the rebuild?
Hey appreciate you checking out the channel. The bike didnt have alot around 16k but usually these bikes can go well past 30-40k.

@@scouts_garagethanks for your time. appriciate your work.
I said a few choice words installing the 2nd circlip on my Harley build. 😂
Lol yee for sure!

Watched this series and I dont even have a DRZ =D
Lol. Time to get one!
