Got my service kit from our host except oil to far away anyway all l wish to ask is does it matter which oil you use as long as semisynthetic 15w/50 is castrol mogul silkoleane it has silkoleane in at the moment dealer used it ps since last on to let you all know bike now has. free flow down pipe to a Goldstar silencer sounds great but just had to dampen down baffle it was to loud have not fitted air injection delete kit as l have not noticed any gremlins would you still fit it l have it on shelf that's all for now just wish you all a happy new year

15W 50 API SL JASO MA2 APPROVED
The JASO MA2 is important I think as it is to do with the wet clutch.
"The JASO MA Motorcycle oil standard is the Japanese standard for special oil which can be used in 4-stroke motorcycle engine with one oil system for engine, gearbox and wet clutch system."

I have discovered that the Euro4 engines does not pop and bang on the overrun with straight through pip, so Air delete kit is not really needed.
