Have a question for all you male problem solvers out there in Ducati Heaven. 1998 Monster 750 with 5300 miles on it. When I start the bike the tach works perfect.... as soon as the bike warms up the tach goes to sleep... as in, stops working totally. I'm guessing that its a sending unit cutting out as the temp comes up???? Any ideas... Thanks in advance for your help... Happy Riding!
