    The MR1 seems to use oil in varying amounts, with Yamaha not giving any official consumption figures ( that I am aware of).. One consideration is type of oil being used, generally Yamalube appears to be low in consumption but some synthetics are reported to be alot higher especially when changing over from mineral. Mine seems to consume more on a flat day when a series of WOT runs are made.
    IMHO it's good practice to get in the habit of checking the level after every ride (when Hot) & add when the level drops near the bottom mark also making sure the ski is as level as possible.

    If you do a leak down test that will tell you if the rings are seated or not. If the rings are not seated you will have a higher oil consumption.

    Doing a leakdown test will show nothing for the condition of the oil control rings,
    yes it will tell how good the compression rings are.

    but I have seen engines where the engine builder stuffed up the oil ring ( clearances,positioning )when assembling , and the engine was a oil pump but still had great leak down figures, just food for thaught.
