Any comments/advice appreciated before I spend a fortune at the repair shop.
My 2009 GTS300 died on me yesterday. Was riding flat out at 80mph when revs dropped and when I pulled over it cut out. Restarted but with low power and dies again if I try to rev over about 3000rpm so limped home slowly. There is a knocking noise from either the bottom of the engine or behind the airbox - difficult to tell. No warning light at any time. Scoot was serviced a couple of months back with new belts rollers filter, fluids.
Any thoughts on what could be wrong? I am worried that the lack of warning light might mean nothing shows up on diagnostic tool and I can't afford to spend a fortune on mechanics looking for the problem.
Any help gratefully received
