sounds right about the same as my observations...
Just bought a fresh bottle of Lube (the other 2 bottles I have have gone missing into the void of my garage..), and planned on doing it, and my first switch to Synthetic Motor oil, (Castrol m/c specific, racing stuff), with filter, today...
but as schtuff always happens, I have to work on 'de flea-ing' our house, as we had a major breakout that went un noticed... and poor dog, (inside 99% of her life) is not comfey.. neither am I or my wife... freaking fleas... man... what a p.i.t.a.
so another 2 days down the tubes...Dog shampoo'd, bloody mess she was... complete 'rip the house apart, vacuume, wash, wash and sterilize couch cushions, bedding, floors, clothes, bedding, vacuume again, spray poison everywhere a flea or an egg could be..... (except on dog... she has Frontline on her, NOW..)
then back to the bike...
as for frequency, I do rear drive every rear tire swap, and pretty much oil and filter also, I don't get more than 6k out of a tire anyways.
now with the Synth lubes, I plan on doubling the intervals...
