As a newbie, maybe this has been asked before, but we intend travelling through Asia and accross to the UK on 2009 XT660r's (fuel injected). We have done Vietnam and some of Thailand on hire scooters, and some of the fuel is a bit dubious in octane rating, and I know parts of India, Pakistan, etc fuel quality is sus. How do others get by using low octane fuel, I know other XT660R riders have been through there. Octane booster? Any help appreciated.
