I'm trying to get my track bike all tuned up and am seeing what yall idle at. I was at around 1500 rpms, but some said that was too high and it should be 1350ish. Is it that much of a difference? Also what do you idle at with the choke on?

 

The maintenance manual, for purpose of adjusting the carbs gives a starting point of 1200 RPM plus or minus 100. I did the adjustment (but think it's still off).

When choke is on, it usually starts the idle at about 1500, but quickly starts to shoot up to about 3000 RPM. I close the choke a little bit to bring it back down to about 1500-2000 range for a couple minutes then close it completely.

 

I keep my idle at 1100-1200. Choke is usually pretty brief, only about 20-30 seconds on the minimal amount possible,then I shut it off and let the motor warm up on its own.

 

New F4i I run it at idle at 1000 even. Is that good or should I up it a little bit?

 

Someone can correct me if Im wrong, but i believe the F4 and F4i being newer are engineered to run better at the lower idle RPM.Our generation is supposed to run higher.

I think 800-900 is on the low side for F4i's?

 

Mine is @1450-ish.

1200-1300 rpm's

 

my F4 is 1400 and the manual calls for 1300 ±100

 

thats fine if ya like stalling out alot. lol

manual calls for 1300±100

 

When I got my bike it was at 1500 and I was havinga hard time keeping it running at times. Seafoam didn't help, but Lucas fuel treatment (the small bottle) dumped in to the tank on two or three occasions over the summer REALLY helped. I've been able to turn my idle speed way down, don't have problems stalling, and it is now at about 1300 give or take 100. You can really tell the difference in those few hundred RPMs.
