Can someone help me with this:
Seems like the bike is running too rich at cold Idle.
Once the Operatiing temp gets to about 154 the bike runs great and idles smooth.
I do Have a aftermarket slip on Exhaust and a dynatuner, I also have a Aftermarket air filter.
I use the yoshimura dynatuner map settings and the race accellerator pump settings.
The bike ran fine and just started acting like this a few months ago.
I have already spoken to the dynatuner people a few times with no help.

thanks in advance

 

What changes were made to the bike a few months ago?

 

Easiest thing would be to delete the variables and go from there.

 

what exactly is it doing?

 

I'll explain what currently happens:
I start it in the morning and it runs for 1 minute then dies, After that its hard to start, like it floods itself out. After 154 Deg F it purr's like a kitten.
Nothing has changed for the past year or so.
I have a Yoshi Slip on Pipe and a Air filter and A power commander.
No settings have changed, and I have spoken to Power Commander tech support.
I have pulled the bike apart and cleaned everything, but the cold issue still exists.
The local moto shop says its the spark plugs, I dont actually believe them.
I keep the air filter clean. Most tend to say its the power commander, but It worked fine for so long, and I dont tinker with it at all. I'm so confused...

 

could be spark plugs.
How many miles are on the bike? On the plugs?

 

about 9200 miles, I believe they are original spark plugs

 

shouldn't be plugs that early....you havn't adjusted your idle or anything??...

 

What should the Rpms be at for Cold Idle, I believe they are about 1200-1500 rpm's. When the bike is warm it seems to run at faster rpm's

 

the idle should be 1300 +/- 100rpms. Cold idle is different because the F4i has an automatic choke, so the rpms should climb for a while until the bike starts to show temp.

 

yeh my bike idles around 2000-2500 for about 45 seconds when its cold and been sitting....which i found wierd cause non of my other FI bikes did that, doesn't bother me, settles right down once it starts showing temp.
