Is my bike too lean?
#31
#32
What name and number is stamped in the main jet?
I am running FactoryPro 138s with K&N filter and a full Hindle exhaust. Stock jets are 135.
My plugs look like this:
(Yes #1 WAS very rich due to a leaking petcock)
I would check
-slider needles for any signs of wear
-diaphragms for cracks or tears
-check float needles for signs of wear. (wear ring on rubber tip)
-remove all rubber / float assy / jets and spray carb cleaner into the 4 brass port on the intake. Also soak all brass jets in carb cleaner overnight.
-clean around the butterfly valve to remove all carbon.
-reassemble
-set the pilot screws to 2-2.5 turns out
-gently lift the sliders up and see how long it takes for them to fall down. Also make a mental note of the sound. All four should be the same speed and make the same sound.
-NOW sync the carbs.
IF you have glue or something plugging one of the slider holes, then the bike has a DynoJet jet kit.

Good luck...

Thanks for the info, Frank. I am not sure where else to turn. I have taken my carbs apart a few times in the last couple weeks and cleaned them last summer as well. They seem spotless. I have basically just taken my float bowl covers off and pulled out my jets and the floats. I have not investegated yet behind where the float pins sit (in the little hole). I have not sprayed carb cleaner in there in fear of harming something. Also, i have not let my jets soak in carb cleaner because they are spotless. I can see through every hole perfectly. Before I sync my carbs though, I will take em apart again and check the jet size. I am not sure if it is stock or not. I am assuming they are not stock jets because my bike has a K and N air filter and a full Muzzy exhaust and it is performing well in the high rpms. My problem is- when it heats up, my idle is crappier so when I shift, the gas or general throttle response is terrible.
I initially thought it was something with my float pins- which is what I will check again before I synch, but they looked fine. They all sit the same and respond the same, and all the rubber points are good. I will do a complete disassembly and cleaning of my carbs before I synch them. Like I said, I haven't gone further than taking my float bowls off and getting to the jets that way- so I will take it all (mostly) apart and clean whatever I see.
