View Full Version : Oil Change - Now Won't Start.

The bike is a 2005 pointy SV650.
I've just changed oil and filter at 8000 miles and ... the fuel pump whirs, the engine spins when I press the button but there's no sign of it firing! I can smell petrol after it's turned over for a while and I've left it in case I've flooded it somehow.
I've checked the kill switch is in the right position and I'm stumped about what I've disturbed that would prevent the bike from running.
Before I start taking things apart, is there anything I'm likely to have messed up?
Thanks
Jeff

How much oil did you put in?

is it on a centre / paddock stand and is the side stand down?

Thanks for the quick replies!
Oil - I've put about 2.5 litres in. Was going to run the engine for a minute then check the level and top it up.
Stand - I'm holding it upright with the side stand up (Sadly my paddock stands are in the garage with another broken bike)

Sounds like you may of disturbed the coil wire or the pickup


Have you tank off or not?

No, just oil drain plug, filler and the filter.
I have just taken the pillion seat off and checked the fuses there - all ok.

if it's flooded do ya not just spin it over without any throttle so the engine turns and doesn't get any more fuel? Or have I got it the wrong way round :)

You need the extra air to try and clear it - its what i do, it should slowly try and catch if its that, or he could pull out front plug and see if its wet, if it is leave it to air then hopefully it will catch on that 1

fair play. I remember at cadwell when irsky dan was trying to start a cbr600 which should have been broken & sold for parts a long time ago. He managed to get it started but with the throttle pinned fully open it just stuttered constantly at about 2k revs.

I told him to let go of the throttle and hold the starter til it started to tick over normally on its own. Problem solved. Then he tried to rev it.... screaming clutch anywhere above 4k rpm lol. It stayed in the van that day!

Is there any chance the OP has left the bike in gear and the sidestand switch has failed maybe?

OK, thanks! Turning it over with the throttle open full did the trick :) Why it had flooded in the first place I don't know but the main thing is that I don't have to get the car out this evening!
Cheers all

For info, most (?) FI systems have a fuel inhibit on full throttle cranking, just for this purpose. I don't know for sure whether the SV does, but most cars do.

With carbs it usually works (but not always) because the gas speeds are so low on cranking that the fuelling goes very weak on full throttle cranking. Depends on the carbs.

Out of interest Embee why do FI systems have that when it shouldn't be possible to flood them?
