Weird start up issue (Video)

[evilzed]

Anyone know why this happens on a second start up from cold? It always happens when I start the bike from cold once it's warmed up it starts up fine every time. My guess it's something to do with the oil being spread across the engine but it should be making things easier not harder to run (Castrol motorcycle 10w30 btw)

And on a side note on the image attached can somone tell me what these pipes are?

They are overflow/air vent pipes, completely normal


Engine .. sounds fine to me but I always use 10w40 ..

Some one else might be able to hear an issue thou

Thanks for the reply, It's specifically on the second start up of the bike the engine feels and sounds like it's struggling real bad and about to stall almost starts to sound like a vtwin

Sound quality isn't great.
There's a hissing in the background (thought it was cam chain slap initially but it carried on after the bike was turned off!!!) that obscures most of the bike's grumblings.
Possibly sounded a bit rough on second start up but without eliminating background noise it's tricky working out what noises exactly the bike is making.

Sounded to me like a misfire, I think one maybe 2 cylinders being slow to join the party.

Well, being cold is the problem I guess. How's the outside temp there 10°C or below? It's pretty normal for bike to ''hesitate'' when it's cold. Fresh spark plugs would help actually.

By the way, why did you put 10W30 in it? 10W40 does the same thing, but can be used in temps above 30°C, which you will experience during the summer.

It is what you call it, overflow hoses. When there's too much of petrol somewhere, it'll overflow via these onto the ground. These are quite small diameter, so they could easily be mounted onto the bowls of the carbs, so when you drain them, the fuel doesn't pour onto the engine.

Fuel tanks also have overflow, so when you overfill it, you don't have to suck the petrol out of the tank yourself.

The easiest thing for you would be to take the tank off, a look where the hoses go. OR, just read the manual.
