Inside the Kove 450 Rally Engine After Real Desert Use

Is the engine healthy underneath or did the desert leave any marks inside that we can see right now? I rode this bike almost 5000 kilometers to the desert and back and even though I did two oil changes I could never see any oil consumption and also the coolant is exactly at the level where I left it when I had it off. There was also no change in engine noise that kind of stayed since kilometer 53 when I got the bike but I want to double check some stuff I read about failing on this bike so today we're going to find out if it's already starting to fail or if it's not. 1500 kilometers almost 2000 since the last oil change. I don't see one piece that should show any kind of concern so I'm pretty happy with that. Yeah no shavings, no chunks of metal, there's a bubble here. That looks even better than I expected to be honest. Yeah the oil of course got some color to it and maybe I didn't get everything out now since I did the oil change cold but that looks all good and healthy to me. I don't really get the point of having that tab here. I mean it does not grip to the shaft at all once the nut is free spinning then this one is gonna be loose as well. That's a bit silly or maybe I don't see it. No, basically just a washer and you lock it but that tab doesn't do much. With all these parts now out let's do a quick inspection. You can see some grooves here. Yeah you can barely start to feel them. Then we have the inner hub. You can also start to see some kind of wear to it but also just some visual stuff. Yeah I'm not gonna bother with measuring all these plates since they look still pretty good and I never had any clutch issues so I'm just gonna use them the way they came. And then the top one is just off center. Now I'm trying to find bottom dead center so we can use an endoscope. So this is the piston from the top down. Now here you can see the actual combustion chamber. We're facing to the intake side now. I'm going down. There are some slight wear marks to it but then you can also see you can still see the cross hatching and when I'm moving it up you see top dead center where the piston meets and there is a bit of build up up there but that's nothing unusual. So that's mostly the intake side here and now this is the exhaust side. You can actually see the exhaust valve up here and then you can perfectly see the cross hatching. There are some slight marks to it but that's something that is completely normal. Here you can see some marks at the exhaust side. The factory cross hatching is still visible. There are some wear marks on the exhaust side and intake side just from the piston going up and down but since it didn't consume any oil I don't think it's anything really deep. So I think that's just normal wear marks from the piston skirt and yeah that's usually what I see on a single cylinder that has been ran for a while. I know engine videos are not really flashy but if you watch the video then you see how I convince myself that an engine is running good or not and there was no play in the bearings in the main bearings so on. Then also the combustion chamber looked really good, clutch and everything so I don't see anything on the bottom end or also on the top end that needs any kind of work other than replacing that shim or that bucket. So once that arrives I'm gonna assemble the bike all back together and I'm gonna find out if the valves stop moving or if they continue to move and then there's also a little extra I got myself for Christmas. You're gonna see that in the next video hopefully and I'm kind of stoked for that and it kind of completes that bike to me so yeah we see how that turns out. I hope you're gonna have a good time and we're gonna see us in the next one. Peace out!
