is well known that SPU can make a lot of problems,may be the epic fault on the MV Agusta. but how many of you may say that this problem resulted in inability to start the bike?And, if possible, give details.I would say that 60% of us have had a problem with the SPU.that makes us rush when we have a problem, and blame SPU!How serious is it? if you havea story , please write here, it may save lot of headache.Thank you

Hi, review this one.

In direct answer to your question, "yes, it is possible", but very unusual. Yes, there is often a willingness to quickly jump to the SPU as the cause of the problem. I believe CAG (like Mitchy) did the right thing by starting a thread specific to failures - this provides far more direct evidence.

Cheers

My 2005 750S is also dead. Died suddenly on highway yesterday, won't start since. No sputtering, etc. just died. Battery turns it over fine, won't fire up.

Bike has 2300 miles and in great shape otherwise.

Disapponting to say the least.

make sure you check all those fuses first - if there are no other electrical gremlins being displayed it may be a simple resolve.

Yes it is. My first spu failure was riding home from work one day, complete loss of power. Lights etc on, but engine no go.... Pulled over, turned ignition key off, back on, started it up and rode a little further before it died again. It would turn over but would not fire up and run.

My 750 died on freeway today. Dash lights up..engine attempts to turn over but will not start.
Fuses on right side near fram all seemed fine.

Damn, this is confusing. How many problems in the same thread?

Those of you posting that your bikes "died on the freeway or died while riding" need to look into the gas tank. It is also common for the fuel hose inside the tank to pop off or rot from the ethanol in the gas.

If you see bubbles, that's your problem. When the bike is running fine, dies, and turns over but won't catch, it's almost always a fuel delivery problem and not an ignition problem.

Why don't you start a new thread matey, or at least go to the F4 section never mind the Maintenance section.

PS. Welcome to the forum.
