the engine stops at the traffic light

[valdis]

Hi, the FZ6 engine stops at the traffic light quite often. I try to change / set idle speed. Unfortynately it helps shortly. the engine speed changes themselves - faster - slower

Some more information please;

Year bike

How much RPM variation at idle?

Your location

RPMs (at idle), Low and high #'s please.

Mileage

Is the bike new to you?

Do we know if the gas is un-contaminated?

Has the bike sat for any length of time un-used? If so, a full tank of fuel, fuel stabilizer added?

How's the bike run above idle, will it go to red line without issues?

:welcome: to this great forum!

Faulty/intermittent kill switches are famous for stalls and power loss.

A vacuum leak will also make the idle unstable. Maybe pop up the tank, pull the air box and inspect the throttle body areas.

Thanks a lot!

Did the bike EVER idle correctly since you had it and did it just start up this erratic behavior?

Was fuel stabilizer added to the fuel when it was put up?

 

[valdis]

Problem was before but not so often. uel stabilizer?// no idea

I'd peek under the fuel tank at ALL fuel lines, vacuum lines etc for any cracking / leaks. Your symptoms are very odd.

You may want to remove the tank while it's up and drain it looking for crap /water in the fuel . Bikes stored W/O a full tank tends to rust inside the tank and the fuel pump filter gets clogged eventually leading to failure. You may want to loosen the fuel pump 9tank off the bike) and see if any rust particles come out. If so, you'll need to remove the pump and dig much deeper.


I personally use Yamaha's RingFree(fuel system and top end cleaner) and "Gas Shok" (stabilizer) in every machine I own, (cage car, yard machines, etc).

The RF is NOT cheap but works wonders in fuel systems. I just used it this am in an "Echo" (commercial) edger that barely ran. Put a large dose of it in the tank (fresh gas), running at WOT, RPM's rose from approx. 5K to OVER 10,000 RPMs. It flushed out any crap left in carb plus loosens up carbons, etc in the top end.. It goes in ALL my customers machines.
