I have a new 2010 FE390. As per the manual I did an oil and filter change and screen clean at 1 hr, then again, 2 hours later at 3 hrs, as per the manual.
What is interesting is that the dealer said "dont worry about the 1 hr service, do it at 3", BUT, with the amount of crap on the lower oil screen, I am VERY glad I did it at 1 Hr.
The oil was clean at 1 hr, but filthy at 3 hrs. At 3 hrs, the upper oil screen totally clean (first time I checked), and lower one semi dirty.
I plan to do my next oil change after a 2 day ride this weekend that will take me to 15 hrs.
I am sourcing cheap Hi-Flo oil filters on ebay and buying in bulk, so I will ALWAYS change the oil filter when doing oil - only an extra 3 minute step, and cheap, so may as well. If I am paying $AU100 for 4 litres of Motul oil, whats an extra $AU5 on an oil filter I say.
Best Regards
