F4 cuts outgreenspun.com : LUSENET : MV Agusta F4 : One Thread
Hi Now that I have purchased my 750 F4, thanks to all the guys for the good advise, I have come accross a new problem. Riding the bike this morning, it all of a sudden cut out. The dash still had power, but the bike just died. At first I thought I may have run out of fuel, but the bike just died. Any ideas?? Could it be the switch for the side stand? Thanks again for all the help and advise that I have received sofar

Yo! Is the bike running whenever you change the gears? Try to turn the throttle and it may finally move forward . . .

Is the bike new? New MV engines tend to do that until they are run in. Does it start easily immediately after this when you press the start button. If it is running hot (over 100 C) they are also prone to cut out when pulling up at lights when in gear. Usually goes away as the engine "loosens" up.

If it is the side stand switch you should see the side stand light on the dash just after it cuts out

Hi The engine's run 44000km. It was in traffic condition, but strangly enough this happened on the highway, doing about 80km/h. If it happens again, I will check if the stand light comes on. Funny though, that after I posted this bulletin, I rode the bike again, no problems.

Check the gas tank vent.

Also check the fuel uptake hose inside the tank (you access it via turning the tank upside down). My MV1000 just cut out and I found it had a split with the fuel hose and it had only done 1000km's. Apparently some fuel types can cause issues by turning the rubber to jelly, however in this case if was a factory fault.

Check the battery terminal connections also.

I own an SPR and have had 2 ECU's go bad. I would be riding along, and the bike would just die. MV has replaced the ECU twice under warranty. All other electrics were fine, the bike would turn over, dash worked etc. In both cases the mechanic would rap the ECU with his knuckles lightly, and the bike would fire back up. It must have been something loose in the ECU.

I think I have found the problem. There is a switch at the side stand which prevents the engine from running if the bike is in gear and the stand is still "down". I went for a ride on Saturday, after we stopped, the bike gave the same problem. I moved the side stand back and forth a few times, and it all came alive. Thanks again for all your inputs, it really makes a hell of a difference knowing that one can ask questions and get such good info back.
