My biggest problem is I'm not totally convinced about the reliability of these bikes, so the idea is to preserve the engine. I don't think I've exceeded 7000 RPM in 900 miles from new. I've owned a different chinabike, an overhead-cam type, and that seemed fine in over 23000 miles. But hey, that's me, I worry about stuff going wrong.

Ok, i can see that thought... I have always been of the opinion of the manufacturer says to use a certain weight thats what i will use...LOL thats all...
As spud has said these bikes are quite reliable given you keep the nuts and bolts tight...and i agree with WaG...they punish the snot outta fhese engines across the pond... I have no qualms about revving mine to 8-10k rpm routinely...i rev it til it dont want to go no more...LOL
