im currently running some 10w40 semi-syth specific for a massey ferguson tractor in my bike. (brother is a farmer and had some left over form servicing his tractor). Have had absolutely no problems at all. (so tbh i would just go for any 10w40 semi-syth, its not like your running a superbike so dont go wasting your money) I used to put in rock-oil from my local shop, that was pretty cheap as well.
