In which section is the secondary oil filter, DCT, Mfg. # 15412-MGS-D21 ? I can't find it?!?
Yep, remember those posts; out of curiosity, I checked the service manual on my 2007 Suzuki C50 Boulevard....its service manual state replace spark plugs every 7500 miles or each year...WTH....I have 102,000 miles on it and changed spark plugs once (at 28,000 miles-thrown in by local mom/pop shop when I had a valve check done by them-they are also my part-time neighbors). It also has the same schedule to replace the gas lines and spark plug cables....LOL...think they want the dealerships to get more service jobs than anything else..my last fill up on the C50, got 52 mpg which is in line from what I have always got(worst average 42 mpg riding Interstate from Indiana to Key West Florida-best, average 61 mpg in the Smokies). Back to the Honda, has 57,000 miles on it, OEM spark plugs and air filter, and my last fillup I got 71 mpg...We’ve had discussions in the past about spark plug life. I’d find the threads but some seem to have been lost with forum software changes. There was no scientific study, just conjecture. NGK themselves has said that their iridium plugs, like the OEM NC plugs, should last around 70,000 miles. Honda, typically conservative with maintenance intervals, is saying 32,000 miles.
People would do well to follow Honda's plug change schedule, but I personally find it rather ridiculous. By comparison automobile engines run plugs far longer than 32,000 miles. I still have the original NC plugs in use at over 46,000 miles and have no intention of changing them any time soon.
Thanks guys for the comments. I really appreciate it.
Yes, you're right, I should inspect the spark plugs before I purchase new one.
The air filter I cleaned about a month ago, after some gravel and dust riding. It already had small oily spot at the bottom (or the top?!? )
As with the spark plugs, owners can set their own air filter change intervals, if desired. I change my filter at no sooner than 25,000 mile intervals. In my opinion, the NC filter has a huge surface area relative to the engine displacement, which should easily accommodate long replacement intervals.I was checking the date and the photos when I replaced my air filter. Actually it was end of May last year?!?!? At Tech Meet at Guy's place
