Nowadays everything can be found. I was scared of entering my carbs until I found this video: https://youtu.be/uFPveis_0Os

I figured, if I ever get lost I can always refer to it and find my way. 

Rejetted, resynced, all I need to manage is the fine tuning, but it runs

Thanks. I watched 1/2 of that video (which is excellent in detail and quality) some time ago but realized it wasn't what I was looking for.  And after one distraction to the next (plus nice days demanding that I just ride) I haven't addressed my problem yet.  

Basically I want to come up from the bottom, remove the float bowl(s) and make the adjustment I need. 

I'm assuming that since I have custom exhausts the plug has already been drilled out.  I even bought stubby finger-tighteners so I'm about as ready as I can be.

So far I haven't found a video showing someone doing what I want to do and I am unquestionably too video inept to do one once I get to doing it.

Thanks for your input.

You mean making the adjustment with the carbs still on the bike? 

I am still in the process of fine tuning my bike but so far found the carbs to be nowhere as scary as I thought. 

Take them off, apart, check which jets you have now. Put them back together and back on. Sync them via vinyl tubing. 

Now the lean drop (part I still need to do) to fine tune the PMS.

Maybe I'm just making too big a deal about it.  All I want to do is cut back on the popping.  It drives me nuts.

All I need to do is 1/4 turn the PMS screw.  Seems like removing the carbs is way more work than needed.

According to Mick it can be done on the bike. 

I just have to hunker down and do it but my happy hunkering days are long gone. 

Actually hunkering isn't the problem it's the un-hunkering. :) Once past 60 crouching and uncrouching progressively becomes a real pain (literally) and I'm 70.

I am better than most but not as good as some.  Even so....

Yes, just turn the PMS out a quarter on the carbs and try it.

True confession - maybe it will help someone else who is as dense as I am.

I thought the PMS was INSIDE the bowl cover and that would have to be removed.  I watched a YouTube video on overhauling the carburetors where I was able to see that the PMS was NOT and it is accessible, albeit tight.  Doh!

So I have turned the screws out, trying to keep them the same.  It is vastly improved BUT the rear cylinder exhaust is still backfiring (I could see the pop in the dark).  So I am going to open that and keep working them to handle the pop.  

Thanks for your replies.

I have always told my buddies that backfiring is PMS too lean but having worked on the carbs and reading a lot on this forum I have found out there can be many causes. 

Seen posts on shaft seal, ais etc.

Good luck, you you fix it soon

Yes indeed. Make sure all of your exhaust bolts are tight and intake boots are in place correctly.

Thanks. I checked the intake boots and they seemed tight BUT the rear one has a little puddle of fuel in the bottom of it.  The front bottom just looks shiny.  The puddle doesn't look right.  Is this expected or is there something needing to be adjusted?

btw I tried to attach pictures but it wouldn't post with the pictures attached.

Make sure your carbs are synched. Some fuel in the boots is normal. Picture posted fine for me using the picture icon in the message window.
