Moto Master in Temuco
Arlen is right - the Moto Master shop in Temuco is one of the few places in that part of Chile that can provide some useful assistance. They don't have a lot of parts, but I was able to get a KLR650 oil filter there a few weeks ago. I asked about a KLR clutch cable and they said they don't have replacements but bring your damaged cable and they will do a repair -- and they showed me the materials they use for repair (I just wanted a spare). Not as good as OEM but better than your broken one, eh? The owner is a good fellow and has helped many a foreign touring rider. If you can get your bike to limp into his shop, and there are spares anywhere in Chile, he will help get them air-expressed (and that is often not terribly expensive) within the country. There is a major airport in Temuco so you could have parts sent from US or other country via courier such as DHL in fairly short time. Customs clearance via Temuco airport usually not a major problem. So if you are stuck in Temuco, Carlos can be a good resource. Also good eating in the city - try Rapa Nui restaurant downtown.
