Upon start up with full choke the 1,3,5 exhaust is warmer than clutch bank exhaust.... after the engine warms up all seems normal any ideas ?

Are all the enrichment valves on carbs 246 connected to the choke cable?

Sounds like a good place to start and adjusted equally to the left side |

Hey Fireman, if you are taking these temp readings at idle speeds, I'd suggest to try opening the pilot jets (if you do not discover a problem with the enrichment valves) on the cool side until you have all cylinder headers coming up to temperature equally. If that does the trick for you, you will notice substantially better performance and power at the bottom end. I just saw that you stated this happens with FULL CHOKE, so my suggestion probably will not apply.  |

I have read that those temp sensors don't work well on chrome. I use water in a squirt bottle.

They aren't accurate for a variety of materials, but polished chrome is one of the worst, with an emissivity of 0.058. Compare that to the rubber of your coolant hoses, at 0.86. |

When doing the procedure, you really don't need an accurate temperature, just the relative temperature difference between the headers, so you can get away with using an infrared thermometer,, but it helps if your headers are black.  |

Those laser thermometers sample the average temperature in the circular field of view which varies by the distance you hold it from the surface. You are not reading the temperature at the red dot unless you hold it very close.
You can put a piece of tape or paint a spot on the header to get the actual temperature on that spot.

Just to clarify I'm using the fanciest of temperature gauges , the palm of my hand, and using it at the exhaust and believe me there is definitely a difference.

YEOWL.... Well, you are the fireman. Did you get a chance to look at the enrichment valve linkage?

LOL haven't yet but I have to go back to the station for training on our new to us ladder truck. If I get to ride I'm gonna take a shot of the bike with our thermal imaging camera it will give a temp as well as verify my palm sensitivity.  |

Here is a diagram of the pieces of the choke assembly components at the carbs. The choke cable pulls on the part labeled 20 on bank 2 4 6 which pulls the enrichment valves open, then the cable numbered 22 pulls on part 20 on bank 1 3 5 which opens the enrichment valves on that side. These parts can be accessed by removing covers numbered 26 and 27. Good luck tracking down the problem, and have fun on that new ladder truck.  https://www.partzilla.com/catalog/honda/motorcycle/1997/gl1500ct-ac-valkyrie-tourer/carburetor-assy |

Thanks again everyone for your help and replies. |
