SV cut out twice...should I worry? - SV650.org

09-08-10, 10:53 AM

Just remembered this actually...

On the AR rideout, first leg, was in 2nd gear giving it some beans around 8k rpm and twice it cut out for maybe 2s before it picked back up again.

Happened within minutes of each other. When I say cut out I mean it felt like I rolled off the throttle completely.

Now I have done a fair few hundred more miles, and nothing of the sort since.

Anything to worry about, or anything I should check out just in case?

Was it both cylinders or just the one that cut out?
I would hazard a guess at a spark plug issue but I dont think it that

I definitely check it out as could do it in a situation that could have you off

No idea if it was one or two. Wasnt wet when uit happened btw.

No idea what to check to be honest.

thinking about it, there could be a few things that could cause it

edit: you run the bike on super expensive or regular unleaded?
- Spark Plug: Tbh it would be v. obvious and the bike would rough running
- Loose HT lead
- Faulty alternator
- Loose battery connection

all could be causes and could not be.

i would consider giving it to a mechanic if your concerned

I normally use normal unleaded, but I did fill up with super at one point (cant remember when), becuase I pulled up at a pump that only had super.

Bike runs fine as far as I can tell. And I have covered lots of miles since, and it hasnt happened again. I'll give the bike a quick once over tomorrow, if it happens again I'll revisit.

Cheers buddy

You don't need expensive petrol.
Did I pass you at any point on the ride? If so, did that look like a bike that has had the living b*llocks battered out of it for 75000 miles on the cheapest fuel you can get? It should.

Were the clocks going mental when it happened? Loss of rev counter signal? Loss of all electrical power?

Hi YC

I know I dont need expensive petrol - as above, I only filled up with super once becuase I couldnt be bothered to find a pump that had normal.

You probably did pass me, but I can only recognise a handful of bikes!

I didnt notice if the clocks went mad or not, it all happened so quick...I think I remember seeing the rev counter needle dropping for those 2s it lost power, but I'm afraid I'm not even too sure on that.

Unless it keeps doing it, no, don't worry.

Is it running OK now? If yes then come back and ask again when there's a problem to find.

Mine did that once. Totally bizarre.
Pulled into a side road and Binky asks me why we have stopped.
I tell him my bike has cut out!!
He gives me a funny look and I look down at my bike and it's working perfectly and had fired back up just before I stopped.
Oh well and carried on.

Could the side stand switch cause this?
