Hi All.
I dont know if there is somebody on the forum with a lot of knowledge in road racing motorcycles? Im kinda new with this and shall give a little explanation of what we plan to do.
We race a Yamaha R6 out of 2008, with extended radiator for better water cooling.
This are 6 sessions, of 20 minutes every 2 hours, so it will cool down, and then go to plus minus 16000 RPM ( programmed ECU )
I think, this will ask for a special oil, and im looking for advice in this.
Mostly, we race in summer time, outside temperature +32 celcius ( 89,6 Fahrenheit )
In the manual, it states: API SG or higher, JASO MA .
When i look at the SEA diagram, the 10w-50 will go to the highest (outside) temperature, makes that the best choice?
Here in The Netherlands, this oil is common used:
Castrol Power1 Racing 4T 10W50
I hope everybody with the knowledge can give his opinion , that will help me with my choice for a great oil
