[QUOTE="ionbeam, post: 1174485, member: 277"] [speculation] Oil pressure won't be low unless: [LIST][*]out of oil [*]plane bearing failure [*]oil pump failure [*]failure of oil to return to the pan (low oil level) [/LIST] In modern engines all of the above are very unlikely until very, very high mileage with the exception of out of oil. How many FJR owners have written to the Forum with these problems? Even the extreme 400k mile bikes seem to have no oiling problems. Oil level low: [LIST][*]loss of oil (leaks); even tickers that were leaking oil into the exhaust didn't cause low oil levels [*]failure to put in oil or insufficient oil during an oil change [*]dire lean angle [*]extreme acceleration(!) [/LIST] These are more likely scenarios. A level sensor will detect a problem before it leads to a low/no pressure problem. [/speculation] [/QUOTE]
