We Tore Down a 10,000 km Voge SR450X Engine Live — Here’s What We Found! — Transcript

Full transcript

1. 0:00The Voge SR450X that's covered 10,000 km
2. 0:04Engine characteristics
3. 0:06This is blogger Chong's bike
4. 0:09Let's check the transmission case filter area
5. 0:11Chong's fans all know this
6. 0:14He doesn't ride gently
7. 0:17And his speed isn't low either
8. 0:19He often goes on long motorcycle trips
9. 0:22As for the transmission cover
10. 0:24this bearing is all covered in grime
11. 0:26Let's take a look at the belt
12. 0:28This is a Guangdong-made double-sided belt
13. 0:32Looking at it like this, there's no problem
14. 0:35There's definitely dust inside the transmission case
15. 0:38The clutch area is also pretty dirty
16. 0:41That's completely normal
17. 0:43After all, Chong has ridden over 10,000 km
18. 0:47If the transmission was spotless when opened up
19. 0:50everyone would definitely say the mileage was faked
20. 0:53Let's check the wear on the front drive pulley
21. 0:56There's no obvious stepped wear
22. 0:59From the wear marks on this part
23. 1:02you can actually tell Chong's riding habits
24. 1:05The obvious wear is on the inner and outer sides here
25. 1:09which shows he accelerates pretty hard off the line
26. 1:11and rides at fairly high speeds
27. 1:14Let's look at the back side
28. 1:15There's quite a lot of dust here too
29. 1:18and that's just on the clutch
30. 1:21Let's take a look at this part
31. 1:23Here
32. 1:23Everyone was asking whether these 10,000+ km were real or not
33. 1:27Just look at how much dust there is
34. 1:29First, it shows he wasn't deliberately riding gently
35. 1:33Second, it shows
36. 1:35that these 10,000 km are genuine
37. 1:37Feeling it by hand, this part is still flat
38. 1:40The wear marks are definitely noticeable
39. 1:42According to what the blogger told us
40. 1:45he also rode a lot on unpaved roads
41. 1:48so the throttle would've been used pretty aggressively
42. 1:51All of this is from the belt
43. 1:53these bits worn off from the friction pads
44. 1:58So how should you maintain the transmission?
45. 2:01If you ride aggressively, do it a bit earlier
46. 2:04If you don't ride aggressively
47. 2:07then you can clean it once every 10,000-20,000 km
48. 2:10Now let's look at the roller weights
49. 2:13These roller weights are actually pretty wear-resistant
50. 2:16Because the whole teardown was livestreamed
51. 2:19a lot of riders saw it happen live
52. 2:21These roller weights
53. 2:23are still perfectly round
54. 2:24there's no section that's been worn flat yet
55. 2:28Let me rotate it around so you can all see
56. 2:31Riders of other models will know
57. 2:33after a certain mileage, the roller weights
58. 2:36will get worn flat on one side at a certain spot
59. 2:39But the material used for these roller weights is really good
60. 2:43After 10,000 km they've still kept their original shape
61. 2:46barely any wear at all
62. 2:48Let's check the crankshaft oil seal
63. 2:50No signs of oil leakage either
64. 2:52The whole inside is dry
65. 2:54There really is a lot of dust
66. 2:57This was a rare opportunity
67. 2:59Chong happened to pass by my place
68. 3:01and the two of us talked about whether to create some buzz
69. 3:03so we decided, why not tear down the engine
70. 3:06that way we'd both have content
71. 3:08He even posted a video asking for opinions
72. 3:11While he was still collecting opinions
73. 3:14I'd already pulled his engine out
74. 3:16so there was no room for him to back out
75. 3:19Okay, the magneto cover is off
76. 3:22Let's take a look inside - still very clean
77. 3:25No signs of the coils being scorched either
78. 3:28The coils all look completely normal
79. 3:31Now let's take a look at the comments section
80. 3:33Someone's bound to say
81. 3:35tearing down at 10,000 km isn't enough
82. 3:38you should tear it down at 100,000 km
83. 3:41This bike has only been out for a few months
84. 3:43so reaching 10,000 km already is quite rare
85. 3:47Ten thousand km still has real reference value
86. 3:51If certain parts
87. 3:53already show wear at just 10,000 km
88. 3:55how many more kilometers do you think it'll last?
89. 3:58Right? So it does have reference value
90. 4:02Okay, let's look at the camshaft retainer cap
91. 4:05You can barely see any wear on the camshaft's contact surface
92. 4:10Now let's take the camshaft off
93. 4:13The surface is also very smooth
94. 4:16Forget about wear
95. 4:18even the usage marks are extremely light
96. 4:21basically after these 10,000 km
97. 4:24this steel lobe shows no wear marks at all
98. 4:28only extremely light usage marks
99. 4:31Look at this valve lifter
100. 4:33you can't even tell it's been used for long
101. 4:36Now let's look at the cylinder
102. 4:38The Voge SR450 4V uses an electroplated ceramic
103. 4:41cylinder liner - look how beautiful this cylinder surface is
104. 4:45Don't even hope to find wear on it
105. 4:48The honing crosshatch pattern is clearly visible
106. 4:51The cylinder surface is shiny bright
107. 4:54Can you all see any usage marks?
108. 4:57Pretty hard to spot, right?
109. 4:59So with wear this minimal after 10,000 km
110. 5:02and it wasn't gentle riding either
111. 5:04do you think this engine's internals can hold up?
112. 5:07Now let's take a look at the piston
113. 5:09Let's check the coating on this piston
114. 5:12it uses a cast piston
115. 5:15This coating has barely changed at all
116. 5:18See for yourselves, right?
117. 5:21Just extremely light usage marks all around
118. 5:25Is there anything else to check on this piston?
119. 5:27Pretty clear to see, isn't it?
120. 5:30The carbon buildup is normal
121. 5:31Even your own bike after a few thousand km
122. 5:34would have this much carbon buildup too
123. 5:36From what we've seen so far
124. 5:38the wear after 10,000 km is way below what you'd expect
125. 5:42Let's look at the one-way clutch
126. 5:45Again, just usage marks, no actual wear
127. 5:48Since you've watched this far
128. 5:50if you like the video, give it a like
129. 5:52Fellow enthusiasts, this is just for reference
130. 5:55Don't interrupt him, okay
131. 5:57The oil pump chain is a toothed chain
132. 6:00made by DRD
133. 6:02This is used pretty rarely
134. 6:05and there's no sign of it having stretched
135. 6:07The timing chain also hasn't stretched
136. 6:11The timing chain brand is also DRD
137. 6:14This is the same as
138. 6:15the components used on my previous bike's engine
139. 6:18So don't worry
140. 6:19about whether it's genuine or not
141. 6:21Its oil pump is a dual-pump type
142. 6:24which is essentially like having two oil pumps
143. 6:27Alright
144. 6:28let's separate the case and take a look at the crankshaft and balance shaft
145. 6:32The inside of the case is also very clean, no burrs
146. 6:36The internal surfaces are also quite smooth
147. 6:39Let's look at the crankshaft - also normal
148. 6:42No wear
149. 6:44Let's check out the balance shaft
150. 6:47The balance shaft
151. 6:48I haven't mentioned before that it's forged
152. 6:51The balance shaft has no issues at all
153. 6:54It has a staggered gear-tooth structure
154. 6:56Now let's look at the crankshaft
155. 6:59The crankshaft is also completely normal
156. 7:02Take a look at its contact surface with the bearing shell
157. 7:06it's also extremely smooth
158. 7:08there aren't even any usage marks
159. 7:11Next let's look at the connecting rod bearing on cylinder 1
160. 7:15Looking at this, it's also just normal usage marks
161. 7:19Let me explain why this shot looks a bit off-angle
162. 7:22because Chong was livestreaming at the time
163. 7:24we tore down this bearing shell live the whole way through
164. 7:28we had to angle it toward his camera
165. 7:31Let's check the reflection on the bearing shell
166. 7:33which shows the surface is very smooth
167. 7:36Bearing shells tend to show usage marks a bit more clearly
168. 7:39any engine with bearing shells will be like this
169. 7:42The bearing shell surface has an extra coating
170. 7:45which is fairly soft
171. 7:46which means once you install the engine
172. 7:49even after starting it for just a little while
173. 7:51the marks on it will already be quite visible
174. 7:54For this bearing shell, we mainly look at the reflectiveness
175. 7:57Some bearing shells have a zinc alloy coating
176. 8:00some have a lead coating
177. 8:02they're all quite soft
178. 8:03you can even rub it off with your finger after a while
179. 8:06which is why the first 100 km break-in period is especially important
180. 8:10If your bike uses bearing shells
181. 8:13which is basically true for all big-displacement bikes
182. 8:16you really need to pay attention during the first 100 km break-in
183. 8:20Take a look at this connecting rod bearing too - also shiny bright
184. 8:23you really can't tell it's been used at all
185. 8:26Now let's take apart the connecting rod on cylinder 2
186. 8:29Okay, take a look everyone
187. 8:32The reflection is completely normal
188. 8:34which shows it's also smooth
189. 8:37The marks on it
190. 8:38are also just normal usage marks
191. 8:40That's the teardown done
192. 8:41But we can't just let Chong fly home without his bike
193. 8:45we still need to put his engine back together
194. 8:47As for the wear condition of this engine
195. 8:49you should already understand it after watching the video
196. 8:52so I won't bother summarizing
197. 8:54The wear is really, really minimal
198. 8:57barely visible at all
199. 8:58and keep in mind this bike did 10,000 km of touring
200. 9:02and the riding was fairly aggressive too
201. 9:05Especially this cylinder
202. 9:06take a look everyone
203. 9:08where are the usage marks?
204. 9:10there's only normal carbon buildup
205. 9:12Alright, let's start reassembling
206. 9:14Apply assembly lube to the bearing shells
207. 9:17then install the crankshaft
208. 9:20The teardown process was livestreamed the whole way through
209. 9:23and I also livestreamed part of the reassembly process
210. 9:27And this engine case
211. 9:28was cleaned with an ultrasonic cleaner
212. 9:31though it wasn't really dirty to begin with
213. 9:33let's livestream putting this engine together
214. 9:35Some fans said
215. 9:37give some precise guidance
216. 9:39and make sure Chong can't even get out of Lianyungang
217. 9:42or have it break down halfway through his ride
218. 9:46I can't bring myself to do that
219. 9:48or he'd definitely beat me up
220. 9:50The prank I had in mind for him, I dropped it
221. 9:53That way
222. 9:54does Chong count as having shown his face in my video?
223. 9:57Take a look at the top right corner everyone
224. 9:59Just from this hairstyle you can instantly tell it's a person, right?
225. 10:03Look, after he washed up
226. 10:05his bald spot is even shinier now
227. 10:08Turns out there's no wear marks
228. 10:10there's really no usage marks at all
229. 10:12can't see any
230. 10:13These past few years Loncin has been improving incredibly fast
231. 10:17especially their production line, which is very advanced
232. 10:20I've filmed a factory-tour video of Loncin before
233. 10:23you can go check it out
234. 10:25Loncin's large-displacement engine platforms
235. 10:27are quite extensive too
236. 10:28and they're all built to be very reliable
237. 10:31Look at Loncin's 500cc engine
238. 10:34you'll hardly find repair shops that ever need to touch it
239. 10:37and also their inline-four 500 and 660
240. 10:40800, and so on
241. 10:42you almost never see them break down
242. 10:44and this engine here is surely the same
243. 10:47the wear amount after these 10,000 km
244. 10:49you've all seen it for yourselves
245. 10:51Alright, let's lift the engine back in
246. 10:53add the coolant
247. 10:55the coolant capacity is 1.3 liters
248. 10:58then add the engine oil
249. 11:00if I forgot to add the oil, that'd be a real problem
250. 11:03he'd come find me halfway through his trip to beat me up
251. 11:06The oil we're using is the unbeatable factory-original oil
252. 11:09this is specially formulated for the SR series
253. 11:12it's fully synthetic
254. 11:14and it's manufactured by Shell
255. 11:15this oil's stability is also very good
256. 11:19So the engine's been torn down, and now it's back together
257. 11:23let's start the bike so you can all hear how it sounds
258. 11:27Listen to it first, then we'll rev it
259. 11:35The sound still feels really smooth
260. 11:37no rattling noise
261. 11:39you can put on headphones to listen
262. 11:43revving it up now
263. 11:54And finally, confirmation from Chong himself
264. 11:56letting me know this bike can hit a top speed of 161 km/h
