Engine shuts off

What's the deal with the EFI bikes shutting off when the throttle closes quickly. Is this what you call "Flame Out"? It usually happens going down a straight at high rpm's then as you approach a sharp turn and close the throttle all the way it shuts off. It does not happen all the time. Is there a fix for it. I tried adjusting the fuel settings but it still happens. Will adjusting the throttle plate stop help?

Thanks Jeff

Have you checked for the slipping fuel pump problem? How much fuel can you put in it if/when it runs out of gas? Does it ever "shut off" like this when the fuel tank is full?

The reason I'm asking is that mine would die during hard braking when at half tank or less and the slipping fuel pump problem had not yet been fixed. (Search for "slipping fuel pump" if you don't know what this is.)

What bike? Is the power-up kit installed? How many miles or hours on it? Once my '08 SMR510 was broken in and the fuel pump problem fixed, it no longer stalls ever except for operator error.

What year & model? I had an '08 TE 250 that did that a few times during break-in. I increased my idle to 1900 and it went away. After after about 10 hours break-in, I put the idle back to specs and it never happened again.

310

It's a 310 with 600 miles on it. It pops as it shuts off. Like the air is cut off to the engine. I have the idle set between 1650 and 1700 rpm's.

Try 1900 and see if that helps.

yea my 09 TE250 did it to me first day i had it....couldnt even get out of my townhouse complex.

I came inside...searched this forum and bumped the idle up.....road around the block at high RPM...never had an issue rest of the couple laps around the block when coming to a stop at a stop sign/light.

as Krieg said...try 1900 for break in and then move it down later.

My '10 was the same way when it was delivered. Adjust up the idle screw to ~1900 - 1975

Where is the idle screw on the FI bikes?

Phillips head screw in center of pic. Can be turned with fingers easily.

Hope this pic works, 1st attempt with "the peoples' phone", lol
