Ok, I have seen this posted before but I have a 97? (or 98 can't remember) XR650L with about oh say 16000 miles.. It still runs great but uses some oil.. Not much but a little between changes and it does smoke on occasion when it is started. I have only put maybe 1000 miles on this bike but would like to know when it is time to rebuild?? I have seen this asked before but no-one responded. I have been told by the dealer and a few threads on here that some blue smoke at startup is quit normal until they warm-up. Mine does not smoke at all when warmed-up.. I was also told that oil usage was common on XR650L (air cooled)?? Is this true?? Should I freshen up my motor over the winter or let it go.. I am a big fan of "if it ain't broke don't fix it". I know the prevous two owners.. The original owner was great with maintenance and kept a log of all oil changes and air filter replacement up until 12000 miles. The second owner was horrible and only changed the oil once with valvoline 10w30 and never cleaned the filter after running it through corn fields. Needless to say I had a mess to cleanup on the bike but this was only for about 3000 miles. Some reponses would be great. DOES anybody else have a 650L with this many miles on it???
