Bought a new VTX1300R in April, broke it in, changed oil/filter a couple times, then @600mi. I did the synthetic MCV 20-50 cut 50% with Delvac1 5-40...(12.5-45) no? anyway, 1950 mi. now, it's getting colder here in WI. I may ride only a few days til next March or so...I'm leaving this fill in for the winter and probably til next year at this time should be 3.5-5k on it then...ought to be fine.
