Took bike for MOT,and looked at new DL250 whilst there.The salesman said they haven’t sold one yet,he thinks the bike is woefully underpowered compared with the competition.Saw a new Aprilia “trail” type small bike delivered in a box.I see they are made in China now.Bike passed,drove home and stripped it down to air cleaner,then removed the air box to access all of the multiplugs under the tank,pleasantly surprised there was no sign of any water ingress or corrosion in any of them.ACF50 greased all of the plugs including the one inside the LH fairing(Thanks Mick).Put it all back together and it runs.Just needs a service and 2 new tyres and we are good to go.
BTW the front end of the air box is a right bit**,glad that doesn’t have to come off too often.
