Hello I write to you from Italy I have problems on my yamaha vmax 250 hpdi mounted on a triton tr20 250 engine hours, I have already been to two Italian dealers but no one finds the problem, so I decided to ask you, I will summarize everything.
The engine works perfectly but randomly and not always when I arrive on a spot and fish for a while and I do to restart the engine starts and dies as if it suffocated, after a couple of days I try again and the engine works perfectly for 5-6 outputs and then the problem still occurs obviously not giving any fault signal on the display.
The compressions are perfect and also the pressures of the various fuel pumps, the cooling system is perfect with the impeller just changed. I don't know how to solve this problem. Do you have any ideas?
thanks Andrea
