Infamous stalling problems have returned

2010 SV is fuel injected

I also have a 2010 SV sport, hope I don't come a cropper! Only at 350 miles so far

Was it happening before the first service? Just wondering if they messed the TPS up in the service...?
Hope it's fixed when you get it back!

he would have to be extremely skillfull to get carb icing in a fuel injected bike.......

He hasnt sorted it out, hes a strange chap to say the least. He just sorta lives with it, the problem will be there quite a bit for a while then go away for a month or 2 and come back.

Its a pointy so no carbs I am afriad.

However rather interestly I have found this old post:

This is the exactly the same fault as mine, however on a different model bike. Seeing as mine is FI I think I can rule out carb icing though. LOL

No it first did when the bike had 12 miles, on but I just though it was me not being used to the new clutch.

id say you should be ok, i read very few tps posts on here My bikes 7 years old now and has just short of 30,000 miles and so far those are the only 2 times it has done anything out of the ordinary, and it was fine 15mins afterwards

Well the story so far. The bike has been at the dealers all day, but because of the horrible weather they haven't had chance to test ride. They have made some changes and been on the phone to suzuki technical etc. I am going to pick it up tomorrow and give it a good 50 mile run and so if the problem has gone away. Fingers crossed.

I'd be looking at either rich running loading it up (very similar problem occurs "hanging down" ... opposite of hanging up... if your needle is set too rich on carbed bike).
Or... some fault with the new fangled Idle Air Valve (IAC maybe, not sure what acronym).

I am gussing grease is to waterproof it so that won't make much difference. So if my symptoms and cause are same as yours it's either new plugs or throttle body balancing, or the TPS?

Yeah, I had exactly the same, in my case after a couple of gentle topple over incidents in the snow last winter that I think knocked the TPS out of adjustment. It went back to the bike shop a few times before it was right. At first they couldn't get it to fault at all, but said it was because the tickover was too low and the bike has a v.light flywheel :\ It did seem that raising tickover slightly did help a bit, as did new plugs, but it was after they did throttle body balancing and TPS that it got properly better again. On the thread about TPS adjustment where there's a YouTube link to a yank mechanic doing it on a SV1000, I'm sure it mentioned that it needs doing at the end of running in period.

The grease is for the pernicious effects of damp on the front HT system. It seems to take only a very slight amount of arcing/tracking to weaken the spark. I'd often have problems after coming off the motorway in the rain, when it had been running AOK at speed for sodden miles, but when I came off the throttle for an extended period of time on the off-ramp it started to mess about and cut out or go down to one cylinder at junctions in town and stopping at lights etc.

I know the above seems to jumble up two separate problems, but they both occurred together for me. The link is that if one pot goes down due to either damp or TPS out of tolerance it makes it easy for the bike to stall, especially if the idle speed is set just a bit low. That's my 2C. YMMV

Here's a link to the TPS thread and youtube link: Re: TPS Adjustment Step-by-Step Pictorial Guide

It's on a TL1000 but virtually identical to the guide originally posted here.

I have manage to sort this after some very frustrating months. Well Suzuki's Technical department did actually.

It was the Pazzo lever on the clutch.

The pazzo levers are manufactured without the push rod on the clutch lever. This means I didn't have to pull the clutch in to start the bike.

Appartently the engine relies on a signal from this lever to tell when the clutch is pulled in, especially at low revs. Hence why it was stalling when slowing down and chaging down gears.

I was very very sceptical at first, but I have now cover 150 miles and it has cured the problem.

Beware anyone fitting Pazzo's to an 2010 bike.

I nearly spat my coffee out at that link, on page 2 "V-power is now under £1 a litre" What? Where? I'm on my way...... oh balls, 2 year old thread


Glad you have it sorted but will this afflict all FI bikes if the Pazzo's are fitted?
