Have you ever adjusted valve clearance? I don’t think the judgment should be based on whether the sound is loud or quiet.
\nI really think you need to open the cover and visually confirm it.
\nValve clearance doesn’t just get wider\u2014it can also get narrower, you know.
\nIdeally, you’d want to check it once when the engine has broken in. \u266a
\nAfter an engine OH, it’s so important that you must check it between 500 and 1,000 km.
\nAt the same time, cam chain adjustment\u2026
\nIt’s automatic, so it’s fine\u2014sure, it’s automatic, but it won’t tighten unless it gets pretty slack.
\nSince it’s only spring tension, the reality is you can’t push it that hard.
\nWhen it’s slack, it really hangs there loosely. And then there’s that indescribable engine noise\u2026
\nAnd once you’ve got the valve clearance dialed in perfectly, I want to sync the carburetor. \u266a After you’ve nailed the valve clearance,
\nwhen you sync it, the engine really settles down. Smooth. \u266a
\nFinally, the engine damper wears quite a bit\u2014that just shows how much the engine is vibrating. \u266a
\nThis really brings it back to life. Now then,
\nwe occasionally get inquiries: “Is the oil Nuutec?”
\nWe use only Nuutec, so we can’t get other brands\u2014sorry about that!
\nSo, no oil change, 32,000 yen flat-rate! How’s that!
\nValve clearance adjustment & cam chain adjustment, carburetor sync & PS adjustment, engine damper replacement & sus bolt
\nreplacement.
\nWhat do you think of that?
\nLet’s get everything properly serviced as we head into spring.<\/p>\n","protected":false},"excerpt":{"rendered":"
