Mike777G- Heh heh, this is sorta like the "flushing extractor lines" thread, but again...I simply don't. OMG, terrible...abusing the Cyclo, huh?!? Yet my older one went over 20 years, much of that in an commercial setting (think abusive employees...found it outside in bad weather a few times) with zero problems and when I sent it in for servicing they said it didn't need anything.
But all that said, sure, you oughta put a drop of oil on that spot at the top of the housing. 3-in-one should work fine.
