I have jus bought a bms tbx 260efi. And have read about three different things on gear oil. The one that baffles me most the manufacture suggest 10w-40 motor oil for gear oil. Is this safe? Tha manual only tells me how to change it. No quantity and no spec on what oil. I'm confused as this is my first scoot. Some one please help!!

Just get motor oil for you crankcase and gear oil for your transmission which has gears and bearings. 80W-90, 85W-90 etc.. I use 85w-140 to quiet the gears meshing and also helps in leaving a better film of oil on the gears.

Some manufacturers recommend engine oil. Yamaha does in a majesty for one.

with 10W30 engine oil, you notice a minor performance improvement, and possibly gas mileage improvement. But at the cost of engine life.
I put 10W40 in my TBX-260 EFI, it's running noticeably more stable, and increases life.
15W40 is manufacturer recommended oil, and I would put that in there, just that the shop was out of that oil that day.
If you really need a performance edge, like on the track, or have a friend with similar bike and do some drag racing, then get 10W30, but generally, if you prefer a long lasting engine, get 15W40.
For gear oil I use 80W90, but next time I might also use 85W140 or something...
