| I have been using Shell in my ST4 now for a couple of years with no problems.
More critical is when you start the bike, let it tick over for a few minutes before you give it any revs. The oil drains back down from the rocker feeds even if parked overnight and it takes a good 30 seconds till you have oil on some of the rockers. That is where most of the damage is done to teh rockers.
Finally change the oil if it shows signs of going black, rather than on sopecific milage. |
