    You did well with the engine disassembly and learned a lot. As soon as I saw the damage at 07:39 I knew it needed proper repair, or even replacement. When I heard that you sanded it smooth, I was almost certain that was going to cause problems. Typically when journals are scoured like that you can’t simply make it smooth because it’s already lost material. You might get a nice looking finish, but the clearances will all be too great because of the removed material. To repair it, ideally you’d clean it up, do fresh alloy welding, and then machine it back down with a mill to the correct tolerances. As most of us can’t do that, it really needed a replacement cylinder head at that point, or taking it to a machinist (not worth doing with a DRZ when cylinder heads are so cheap...it’s not like a Ducati superbike). BUT...you learned a lot about your engine, and you’ll be able to fix it properly next time.

    Thanks mate! Absolutely! My car mechanic friend who helped me get the valves out, give me the same look/message as you. In fact But the innocent inexperienced newbie in me was being wishful. I was told the head needed to be replaced, but i thought of myself of the underdog who persevered with his sandpaper and would eventually triumph. Strangely at that point the cheapest (used) head I could find was $1200, and the cheapest Engine (changeover) was $1700; so when I could throw in some more money and buy an entire motorcycle it just didn't make sense to try save this head. So that's what I did.

    Thanks for the story! The more I've worked on stuff the more I've realized that the difference between "can do" and "won't" a lot of times is intimidation. It has become easier and easier for me to do jobs as I've gotten more and more familiar with stuff. Most mechanical tasks are not super complicated, but they can seem intimidating, because there are a lot of unknowns. Some people with zero experience have zero fear, and they delve into projects with nary a care. Others have lots of experience, but are still intimidated. It's all a game! Concerning the cam journal I honestly wasn't sure what your outcome would be. That is a precision surface that is fed with oil under pressure, the oil film floats the cam. If the clearances become too large and/or the surface is not uniform the oil film can't subsist, and then you have the metal-to-metal contact. It would've been an interesting experiment to see if a thicker weight engine oil might've given you more running time. People may disagree, but there are always the amazing cases that defy what the experts say is or isn't possible. Again, that's not a "friction" issue so much as a plain-bearing-loss-of-oil-pressure issue, which then turns into a friction issue. Look up mototuneusa.com, Pat McGivern talks about all the controversies surrounding proper engine break-in and how areas in engines with plain bearings (such as your cam journals) don't break-in on a new motorcycle (they're either properly sized and operate as they should, or they're not and seize, hence the "easy break-in" is a fallacy).

    Absolutely mate! That's why I love mechanical things, as you take things apart you learn about it. All those mysterious internal bits start to make sense! You know what, I think you're right! Sanding off too much probably meant there wasn't enough oil pressure to keep it 'afloat'. But at that point, the head was already messed up. So I guess it was worth a try. Thanks for the link, and also thanks for taking the time to share all that! I genuinely appreciate it, and love hearing these things!

I know lots of people would've told you not to sand that journal, that it would never have "worked." I'm glad you did, and I'm amazed it was fine until you got to higher speeds. In an emergency, that fix could've saved you.

    I use a ratchet strap to get the carb back in. Taking it out is just a matter of disconnecting throttle cables etc, twosting sideways and pulling it out. I added a clip in one of my vids but will make another one showing the process. As far as metal parts- replace them. The cost of a new part (and seals) is way cheaper than trying to fix it without machining, and is the cost of owning a bike. With the service manual, you can strip the engine completely and rebuild it. Just follow their instructions. I recently resolved a hard start issue by replacing the cam lift shims. The timing chain didn't match the manual as well so I was reluctant to correct it. I eventually went by the manual specs, put the bike back and holy cow the thing ru s so much better. Trust the manual. KZread is good to understand the procedures, but you need to follow the specs.

    Absolutely.. we can only learn from our (or each other's) mistakes... Splitting an engine to sort out a bottom end feels like a big challenge.. then again, taking the head off felt like that the first time too. You might be able to sort it out, an in the process rebuild the engine too. But at the same time, getting another engine might be a easier solution. How did the piston (rod) bend though? I would think that for a rod to bend there must have been something that prevents the piston from going all the way up? (like when the engines waterlocked)

    Sometimes it can be difficult to know if the DRZ motor sounds good. There are heaps of youtube videos of DRZ owners wanting to know if "Does this motor sound OK to you?" A stock DRZ motor sounds like a bucket of bolts have been thrown in and If you run a skid plate, it sounds much worse. On top of that I wear ear plugs as the DRZ is a loud single thumper, so may not hear anything unusual. The good thing is that parts are cheap and a good opportunity to add a big bore kit and ACT gearbox.

    The automatic cam chain tensioner that comes standard with this bike is a known weak point, I would reccomend getting a manually adjusted version, since they don't cost much, and will save you a ton of grief. Another weak point, as I have discovered(but also a weak point in other bikes like this), is that you have to be careful when changing out the chain sprocket on the drive shaft, as the drive shaft is "floating". On the inside of the case, the there is a slide bushing on the shaft that could get deformed if you use too much torque on the nut holding sprocket in place. This bushing can cease on the drive shaft, and ruin the transmission(happened to me at a busy red light). Use a torgue wrench, 110 Nm. Some say you even should put red loctite on the axle spines(not the thread) to take up the slack between the axle and sprocket to make sure that the nut will not accidendentaly tighten itself, by the slight movement of the sprocket. Personally I think have right tightening torque should be enough though.

    I'm still on the fence about the ACCT vs MCCT. I see people switch to MCCTs and the 'chatter' simply disappear as they tighten it, but the ACCT on the DRZ is one of the few things that's actually evolved over the 20 years. The past ACCT were essentially a rod at the end of a spring, so the spring was constantly taking a pushback from the chain; but the newer ones have a ratchet along the rod. So as soon as it jumps a tooth the ratchet locks in and prevents the chain pushing the spring. When I removed my old ACCT, I actually did a very rudimentary comparison between the springs, but the old was as firm as the new. But since I had bought it, I put the new one in. And mate, the next time you're in Melbourne, do give a shout out, we might even be able to organize a ride together!

    You reckon? Cos the cam was barely turning without any sanding.

    @@OnTwoWheels the cams are not supposed to "just move freely in the hole"... This is an gliding oil bearing, there are very very tight tolerances for this whole principle to work. If the space is too big or uneven the oil pressure is not build up properly on the needed area or worse you are wasting precious oil pressure and let the other places run dry. These bearings have tolerances of one 10th or even 100th of a mm and you just destroy it with your fingers and sandpaper. No offense but I new you screwed up the moment you said you used sandpaper :( poor engine. (Sorry I'm German and English is not my mother tongue)

    Mine had done 24,000. Honestly it would have run a lot longer if I had gotten around to replace the cam-chain earlier. I blame only myself for my DRZ's early demise

    As someone pointed out, when it was sanded down, it increased the tolerance. This meant there wasn't enough oil pressure to keep the cam suspended. When i saw the scorching I knew it was a gonner, but hey, if it needs replacing anyway, n harm trying one last hail Mary on it.

    So what was the problem on your test ride? Did you forget to put oil in the bike 😨 Or was it the sanding on the grooves on head?

    It was the sanding; before the sanding, the cam wasn't rotating as freely as the other. The sanding helped; but it wasn't a 100% fix. So it was 'managing' at idle and slow speeds, but during the test ride at freeway speeds/RPMs it couldn't make it. And the situation aggravated itself and went past the point of no-return.

    @@diydirtbike4625 Yes there was an oil supply. My theory is that the metal filings that were mixed with the oil got into the cam journals. This scratched and deformed the surfaces on the cam shaft & journals. Because of this, the cam wasn't turning as freely as the other. by sanding the cams and journals I expected to remove the deformities allowing the cam to rotate freely. I also didn't want to over-sand it as that would then cause a play between head and cam. I sanded it down to a level where it rotated decently, but it wasn't optimal. So after reassembly, it rotated fine and didn't have any issues; but at high speeds the friction probably caused the metals to expand, and then add more friction, and then heat up more, and go in a vicious cycle. This went on until the components on the head got so hot it overheated and couldn't lock in compression anymore... That's my theory.
