Can I have the last word on this one...........for a while at least . I have put 10/40 semi synthetic in my 400 this time. Definately no clutch slip.
Once Iv finished restoring my bike I was going to use 10/40 semi for a couple of standing heat cycles as it's quite a thin oil to flush out any crap before filling with the correct oil for normal riding.
I always use this stuff which is on offer with free delivery - Never had a problem.http://www.carparts4less.co.uk/cp4l/p/accessories-engine-oil/engine-oils/engine-oil/10w40-engine-oil/?521776011&0&cc5_245&utm_source=bm23&utm_medium=email&utm_term=BUY+NOW&utm_content=24+HOURS+ONLY+%7C+Huge+Savings+on+Best+Selling+Oil%27s&utm_campaign=September02+-+Oil&_bta_tid=3.h3A.CaeQug.Ew_L.AfJ0RA..Aw2wWw.b..s.Ah0n.a.VebkwA.VebkwA.A0SjfwKevin
