clogged fuel filter?
Awesome, thanks - I'll research how to unclog it.
While not impossible I find the idea of a clogged filter unlikely in Oz, our fuel is generally very good.Can I suggest that if this happens again...1.) Open the tank lid. Does it 'Whoosh' when you do so? If so the venting system isn't working.2.) Does it suck air in? If so the vent that allows air in to replace the leaving fuel is blocked.3.) Are the fuel lines to the injectors kinked to a degree to impair flow?FWIW I haven't felt the need to replace the fuel filter on either of my 120,000 km shitheaps. They run just fine.Pete
I remember exactly the same happening to me in the early eighties!!I was riding through London on my Le Mans II, no such thing as the M25 ring road then and the traffic was horrendous.She started running like a pig, so I parked up for half an hour, then carried on...she was fine.
Replacement, although a crap fuel filter usually turns up on full throttle openings first. Does the V7 have a thermal shutdown in the ECU?
Take a plug wrench w you. The next time it happens pull a plug. If it smells of fuel, then it's getting some, and it might not be a fuel problem. Then test for spark by connecting the plug to the ignition boot, laying the plug on a metal part so it's grounded, and cranking the bike to see if there's a spark at the plug. Another thought, it could be an air leak at the manifold, but those usually aren't temperature related.
I wouldn't expect a thermal shutdown to cause poor running. It would be no running at all.
A similar thing happened to my 2014 1TB in 38 degree peak hour Sydney traffic 25km from home. Rough running, smells of unburnt fuel, surging idle, 3 cooling stops to limp home. It ended up being a dirty air filter, oil in the airbox, dirty throttle bodies, fouled plugs. The airbox was cleaned, and down the manifolds to the throttle bodies, new air filter, new plugs, re-set the TPS & ECU a couple of time. Then worked fine. And since then I've only filled the engine with 1.9 litres of oil (not the 2L specified in the manual) and have not had that problem in the 60,000km since. I am careful to replace the filter & clean out the airbox each service. I have done peak hour traffic in the heat since & it's been OK, but I am still very wary in these conditions.That being said, this MAY not be your problem, merely similar symptoms, but it is a relatively easy thing to try early on, before, say, taking out the fuel pump to check it out. You can re-set the ECU by removing the battery's negative terminal for a few minute. I believe this starts the auto learning again.And just recently, The 2TB recently just upped & died on the way home - still had lights, starter, fuel pump, but no fuel burning - diagnosed at the side of the road to be a short in the injection services circuit - blown fuse, which blows again each time the ignition is switched on. Still hunting that short. A completely different problem, it seems.Good luck. Let us know how it goes.

Is it enough just to mop this oil up with a rag? Spay some throttle body cleaner in the intake and wipe around? ".....Sent from my SM-G935F using Tapatalk
I'd try to avoid dismantling first - wasn't necessary for mine. Paper towels to mop up the oil, more to to wipe down the insides of the manifolds, and down to the throttle bodies. You could also try finishing off with a clean microfiber cloth dampened with carb cleaner down there - say, on the end of some kind of flexible stick/hose/wire - to ensure it's all clean. Then a new filter (the stock paper one ), new plugs, & re-set the ECU & TPS. A re-flash would probably not go astray. You have replaced the spark plug caps with NGKs haven't you? While there, check for corrosion at the ends of the HT leads. Perhaps nip off a few mills so the copper is bright, just in case.
It's a little late for me to be posting, but that little dab of oil doesn't look like any big deal to me. Certainly not enough to "kill" an engine. I'd be looking elsewhere.
Ok, I've been busy, but here are some suggestions in response to the thread:1. It's NOT a clogged for filter, that wouldn't be intermittent (not a pressurized filter like this).2. It's NOT the half plastic filter, again that not intermittent, if it split (rare) it would simply strand you and never work again.3. It's NOT vapor lock. A. The whole volume of your tank would never become vapor (to the point the pump wouldn't have liquid to circulate) and then return to liquid later. Equally sealed high pressure lines aren't going to allow vapor lock. I'm not sure I've ever heard of a verified case of vapor lock on an EFI motor.4. It could have been an electronic intermittent fault caused by heat. The hair dryer suggestion is not bad.5. But mostly, listen to and check Pete's suggestions and go from there.
Is that utter fantasy ?
