I supppose if you want the stems of the valves and rockers in oil...drill a small hole on the bottom of the rocker cover....tap a thread and put a small bolt in with washer to use as a drain. do same for top about half way and use as a fill ......with cover back on the oil will /should sit in the rocker covers and allow the parts to run in oil
Well, it's supposed to be a clone of the R71. So this one is a 750cc I don't know if anyone has made a list of parts that would be interchangeable. If they cylinder bore is the same it would most likely fit.
I don't understad, it doesn't feed oil because that's the way it was designed? Or is a malfunction? I relally love this bike and i want to buy one, but first it would be really interesting a review of the relliability of it. Thank you for sharing...
It does not seem to feed oil. When I hold the rag infront of the valves you can see crank pressure blowing the rag, when I removed the valve cover there was only a few drops of oil in there, not enough even to drip on the floor when I removed it. There was metal flakes in the cover, not good. It's only done just over 150miles on a new build engine. The whole bike was restored in China and sent to me. The engine oil,gearbox oil,and final drive oil was full of metal flakes and grit. I was really looking forward to driving this bike but it's been in my workshop since I bought it from a UK importer. He's trying to help me repair it but it's everything, front forks leaking, wheel bearing destroyed from shot blast etc. It's a great bike but this one was built in applying conditions by amateurs.
seems there is something wrong with the oil pump. The oil should show up after a few seconds of running I replace the original oil pump for a better one that deliver at least twice more oil than the original. That motorcycles are great but most of them are in really bad conditions when I bought mine it was running on the left cylinder only ....
No, I didn't find a solution. The oil that was in it was full of shotblast grit form the guys that restored the bike in China. It's also developed front fork oil leakage and all the rubber parts are cracking open. Total waste of money.
@@jamesconnors4297 definitely change the oil and check the condition of the oil that comes out. Mine had shotbast in it. Now all the rubber for the intake manifoldd have cracked and perished and so have the rubber hand grips. It really depends if you bought the bike running from an enthusiast or it was rebuilt in a dirty backstreet in china like mine was. It's turned into a massive project, but I have the general shape of the bike that I always wanted, ie frame, wheels, tank, forks. If I could get hold of a classic BMW R100 motor I'd probably be best using that. But I might try rebuilding what's here already.

I just started a full rebuild on my cj750. Might look into the oil pump upgrade mentioned previously.
It may run down the pushrod tubes back into the sump tho.
Is this chang Jiang a clone of the 650 Ural ? wonder of the ural head /cylinder will fit ?

@@sivi8272 thanks for the advice.
Работает вполне себе хорошо.
I don't understand your language, I'm sure it was something nice though.
@@northseacowboy its Russian language.
Did you find a solution? New oil pump?
No, I didn't find a solution. The oil that was in it was full of shotblast grit form the guys that restored the bike in China.
It's also developed front fork oil leakage and all the rubber parts are cracking open.
Total waste of money.
@@northseacowboy so if you buy one of these probably strip & rebuild the engine before running it ?

did you find any info that the pushrods had a hole thru them to allow oil ?
Hi James. From what I can remember, there is no hole in these pushrods and it's supposed to operate on oil mist.
I don't have much confidence in that.
No oil, stop stop....
