+1 for Chinese quality control I'm afraid mate. However, now its been rebored and if you cut the valves in yourself you will have removed the most common errors found in the J-copy engines. Also, am i right in guessing the oil you mention isnt specificly for bikes? If so it will be turning thin; water cooled cars don't put as much load on the oil and keep it at a fairly regualr temperature, plus you don't have the shear forces a gearbox puts on the oil. Try proper bike oil, chances are it will fair much better. Lovely looking bike and its givewn me somke real motivation to get a project thread going for my Honda 200 I use Putoline DX4 which is made for bikes with shared engine/gearbox oil. Interested point about air/liquid cooled though, i hadn't considered that! Thanks for the kinda works. Hurry up with the project thread!

Your bike is SICK! I love the style that you've chosen and I love little bikes bikes that have been tweaked just the right amount! This is exactly the kind of project Ive been planning to do for myself but Uni, Work and other projects always get in the way! Wishing you the best of luck with it! hope the oil issue isnt too tough of a fix. it'd look pretty cool with an oil cooler in too I should think.

Thanks a lot, I appreciate the kind words Which Uni are you at? I'm in my first year at Plymouth, I'm hoping to get the bike down here soon.

Got the head back from having the inlet seat recut (3 angle). I thought i'd have a look at just how bad the inlet valve was. I shined a torch up the inlet port and slid the valve into it's seat, and rotated it from underneath. The video shows how bent the head of the valve is! That'll be the low compression and the tapping noise. Here's a pic of the 3-angle seat. Now i just need to get a new inlet valve and assemble the head. That's it for now i'm afraid.

Don't forget to blow out that spark plug hole! Don't worry, it got a thorough clean! Bike is all back together now, I need to get some photos and videos up (been doing some filming on my GoPro). It goes ridiculously well with the rebuilt engine. Top speed is still the same but it'll wheelie in third gear now, rather than only just managing it in second like it used to.
