API spec
Dr Bike har säkert tagit upp detta i tråden tidigare men för den som undrar över hur man ska tolka API-klasserna kommer dom här. Notera att Motuls olja inte rekomenderas för motorer nyar än 2004!
Nu är det ingen större fara på taket eftersom japanska MC-motorer generellt har ganska låga krav på oljekvaliten vilket man inser om man orkar läsa sin manual.
