Hi
How about clutch problems, if you use syntetic oil?
Is that not why the manual says semi-synt?


btw
Happy New Year

Hi Bimbam (that will be Thank you mam  :lol )
[size=1em]I really don't know the answer, Haynes say it is OK to use fully synthetic, no, not just OK but they recommend its use, others say use only semi synthetic, because of the nature of the Fully Synthetic oil messes with wet clutches, but if you use Semi synthetic oil does it only semi mess with your clutch, that does not make any sense at all. It is either OK to use synthetic or not there can not be any half way.[/size][size=1em]IF Yamaha say no to synthetic oil either fully of semi, what the foc is the difference between a high revving 4 pot Yamaha engine and any other high revving 4 pot motorcycle engine.[/size][size=1em]The Fully Synthetic oil I use (and I am not saying it is any better or worse than any other make) is Shell Advance Ultra 10W-40 and it says on the label [/size][size=1em](Bearing in mind this is Shell and they are not exactly small in the field of oils and fuel)  'Ultimate Performance for ALL bikes'. [/size][size=1em]Now it seems to me that most makes of motorcycle have a wet clutch, I say most as there a few that don't , I believe that some Ducati have a dry clutch system.[/size]

[size=1em]Now if Shell are to make a BOLD statement like [/size]'Ultimate Performance for ALL bikes' I think it must be true, cos, they would be in deepest doo doo if loads of motorcycles across the world all started braking down because of misinformation on and about one of their products.

[size=1em]Plus what is the basic mechanical difference between one high revving multi pot engine and another? Its Pistons, Crankshafts, Valves, Bearings Camshafts and Lined friction plates coupled with plain steel plates in nearly all clutches, most run in oil and operate in exactly the same maner, plate apart no drive, plates together drive.[/size]
[size=1em]Basically as said in other posts, use what your comfortable with, and, if it all goes tits up you only have yourself to blame.[/size]

[size=1em]And of course Yamaha would love you to use their products [/size] :rolleyes  including their bloody expensive Fork Oil :'(
