Hmm strange engine pause?

[Fenster]

Well just took it for a spin and found out something new. It have never done this before so I started to wonder.
I was in 5th gear I think, driving quite slow....and gave full throttle. And the bike went...GRROOOO...(pause for one second..then)...RRRROOOUUUUUUHHHH...back to normal. I hope you guys get the point. :-D
It behaved normally and made a pause for one second and then continued. What can this be? It was almost like there was no fuel for one second and then it started to flow again?
Has this happened to anyone?
Ideas?

sounds like you we're out of sparks my man :hammer: :-D

Possible some trash in your fuel, I've had that happen with cars before. Maybe just some bad gas?

It's the sound of someone destroying their engine. Hopefully you did this when your engine is cold so you can give your rods the proper bend. Lugging an engine is worse than over revving.

Maybe it took a second for the fuel map to believe you really wanted to do that. Or, it was giving you a chance to change your mind.

What rpm were you starting at?

Ha ha maybe my engine is smarter than me then! :-D
Oh I don't know exactly but maybe around 4-thousand?

It feels like the spark idea is the best so far! :-D

Oh and it has only happened twice i might ad.

[Fenster]

Or maybe more like 5 to 6 now that i think of it....

Hmm, never heard of %&/() the tank before...maybe it´ll start my old honda right up?

Actually, it's caused by fuel being dumped into the cylinders and killing the spark. Check your plugs. I bet they're black.

When you whack open the throttle at high manifold pressure, the ECU dumps copious amounts of fuel in to the cylinder to deal with the sudden increase in air. The problem is that there's not much increase in air because you're lugging your engine. That causes an overly rich condition that the plugs just can't set off. After the enrichment period the fueling goes back to it's normal lean self that the plugs can actually light.

Again, check your plugs. If you've done this very often, they're probably fouled. That is unless you like this sort of thing. Then don't change them and it'll get easier and easier to do.

Oh, and start saving for that new engine. We'll want pictures of the rod through your crankcase, too!

It's water in the fuel. Happened to me and went away on the next fill up.
