changed oil an filter when I got back from a good fast ride from Bristol today whilst oil was still good and hot. note to self...have drain bowl further out next time. It don't half fly out of that side drain plug when its really bloody hot! as usual used gen oil filter and yamalube ten forty semi synth. You gotta love the way Yamaha put you a new drain plug washer in with the filter...
Got the HD evo fatty to do weekend, Thats a right pig. Engine oil (including a purge coz its dry sump and there will be a good pint in the engine), primary drive oil (chain and clutch run in an oil bath behind the derby cover) and transmission (gearbox) oil.
