Hi I have a (new to me)59 plate 796 Hypermotard on 14000 miles, it's got one or two niggles that I need to sort out, I think they may all be tied into one another ? The engine management light appears if I ride in the upper rev range before I've covered 10 - 15 miles, I have to stop turn the engine off for 90 - 120 secs then the light will disappear. Whilst out on a ride recently the oil light came on after 30 - 40 miles of spirited riding, when I accelerated, weighting the back wheel, the light would go out, when applying the front brake the light would come on, I obviously thought I was low on oil, crept home and found the oil to be just under max. Topped it up anyway, went out for a ride the next day, within 10 miles the oil light was on and this time stayed on permanently, this evening I've changed the oil and filter and used 15w 50 as recommended in the Ducati manual, went out for a quick ride, light came on within a couple of minutes and stayed on. Tomorrow I'm thinking of dropping the oil and cleaning the filter inside the rhs engine casing to see if that makes a difference ? I also noticed this evening there is a slight covering of oil/leak coming from the nuts on top of the lhs of the head ( will post up pics tomorrow) So for now i'd appreciate your help and advice on what could be causing the oil light/engine management lights to come on, what size allen key I need to buy for the engine casing and where to get the correct size crush washers without going through a dealer and paying extortionate prices thank you..
