I am through half bottle of sea foam so far has done no improvements. For me, pipes did not make any difference to the issue I am facing. Hesitant to remove carbs especially not knowing what I will be looking to fix. Bike otherwise runs great, idles all day, charges battery at idle etc etc

My bike has a K & N and Kerkers and I had the carbs off 4X, yes you read that right....FOUR freaking times.
There was an upside - I can now do a carb removal in 20 minutes tops!!!!!
My initial problem was created by giving the carbs to my local Vintage Club guy who had just acquired a soda blaster - well f#@* me it took me a week to get what I thought was all the soda residue out of the carbs, add my Randakks bits and pieces and shove her all back together.
Bike started perfectly but then ran on 1 or 4 or 2 or 6 cylinders .
Long story short it now idels perfectly and runs unbelievably well except for the burble/miss/stutter at a point where I believe the pilot jet doesnt function anymore as it transitions to the main jet.
Im also starting to think it may have some megaphonitis from the Kerkers.
I also see there is some issues about the K & N.
Lucky me I have a set of stock pipes and a stock filter, so once the damn rain stops Ill try those before I take the carbs off again.

Take that K&N and throw it away as far as possible and use stock paper filter
