hi guys, my bike has separate oil for the transmission and for the engine. Can i stick JASO MA2 inside the engine and Transmission? If not what oil specifications should i put in my transmission and my engine? Does putting JASO MA2 in the engine and the transmission ruin the bike? Also, are the castrol products any good? I am talking about their oil (castrol activ 4T) , their chain lubricant spray and the air filter oil spray. Thanks!
