personally, I'd have a spare spark plug, but no other engine spares with me. firstly cos its so reliable, second cos you have space for spares and tools to work on the engine, third cos once you start with spares, you can never stop!
far better to have a few spares back in the UK eg have a complete chain and sprocket set sat ready to go. or a savvy mate who can get stuff shipped double pronto without incurring big import duties.
all I'd carry ... front and rear inner tubes (with heavy duty fitted), spare air filter and oil (0.5l), front sprocket and its retaining plate + assorted bolts and a few zip ties. you'll probably only get a crappy chain, but you won't get a front sprocket!
on sprockets, 14/48(?) standard is 1) too low and 2) wears fast. 15/45 gives good gearing and odd teeth wear more slowly as the stretching links have to wear both faces. an alternative strategy is to go "even" and slip the chain round by one tooth when/before you can replace it. sadly, neither sprocket is reversible to get extra live, but don't leave home with that silly alloy sprocket ... it lasts very well till it starts to wear and, then, its like butter
