Roy,
The owner manual that you get with your bikescooter
Engine oil 10w40
Transmission oil 10w40 (there is no transmission oil)
Final drive oil Hypoid SAE90
Just goes to show that you need common scents when reading any service manual, and not to believe every word in them.
As an example my manual requires me to remove the trunk case (storage box under seat)
Remove :-
Both under skirts
Side skirt that run up the side just under seat line
Rear passager back rest and cowling
All this to get to 2 bolts that hold the storage box at the rear
And all of this just to remove 1 air cleaner bolt and breather hose from rear air cleaner box
When all I did is pull back the edge of the storage box and inserted extension bar down to remove bolt, and remove breather hose from rear of rear wheel arch.
So thats what all that wormy stuff is in your head is for, think about it and use it.
Have a very merry 1
Rgds Greg ...
