I might be wrong. I thought it was the battery but maybe not?

Bike has a harder time to start. Gas mileage is good so I don't think its the pressure regulator(I took a small hose off of it to see if it was wet. It was dry). Battery is stable around 12.5 volts. When key is turned on it dips in to the high 11's. It kind of shudders like its trying to start and then it always does. Once its super warm like 120 degree's it will typically start a lot quicker.

Think maybe plugs??

1st. Bike year & model.
2nd. please clarify when key turn on, (what) dip to 11rpm? Do you mean the rpm needle kick to 11rpm.
3rd. So on a hot day 120 degree, bike starts easy...wow 120? Where you live?

When was te last time you gave her a tune? Pull the plug & see what's going on? If hard starting but does start? Something is not balance air, gas & ignition.

Hope you get it resolve soon but please provide more detail of bike and current issue. It's tough only by word...some member even post a video.

I'm interested in this as well. Mine does something very similar.

I changed my FPR, but what is this hose test you do to see if it is wet or dry? I read this in another thread, but can't find that thread or why it was mentioned (I assume to see if the FPR is not working correctly).

Thanks.

Battery shouldn't dip into the 11's. Plugs need changing after 14-16k [book says 16 but I can feel the difference around 14 normally]. Bike starts easier once its 120*+ because the oil is warmed up and already pumped through the bike hence its easier to turn it over which means less load put on the battery.
