Good, there's enough brass holes in the world.

You grind the ribs off the carb inlet and the Noss slides right on,,then either use silicone or do what i did and JB WELD it on...i like it solid

Gotta be carefull to not plug off the 2 holes in either piece though..i had it on and done in 5 minutes

Same here. Ground off the one rib. Applied the JB Weld and slid on the NOSS. Scrapped the excess JB off. Clean as a whistle.

Im at 450ft elevation and the adjustment screw on the carb is set around 2 1/2 turns. Stock motor and exhaust. Although I did put in a K&N filter in the stock airbox.

Any idea what I should be looking at?
Are you running the 8 heat range plug on the highway? If yes try the 9. I had same stalling problem you describe and the correct heat range plug fixed it.

Installed the FMF Q

Now I have de-smog, snorkel gone, uni-filter, dave's mods, 55/158 jets and about 1,500' elevation.
Started the bike and maybe I didn't warm it up enough (how much is enough?) but after a minute of half choke when the rev's started to die down, I fully (un)chocked and ran for another minute and then rev'd the engine a few times. A faster crack of the throttle had it cough and pop. Normal?

I believe I am. I'll try swapping in a new 9 plug tomorrow and see if that helps.
I got the mixture kindof tuned to the point where its not bogging, idling rough or dying anymore when I come to a stop. But, if im going anything over 40mph and pull the clutch in and try to coast with the motor idling it dies . No problem bringing it back to life letting the clutch go though. Lets see if the plug helps. Thanks!

My fuel screw is fixed or basically sealed. I can't get at it. There is a brass plug and that's it.
I can try 52/155 I guess. Not allot of fun pulling that carb.

Post a picture, usually with this type "brass cap over screw" you drill into the cap and pull it out with a screw giving access to air screw.

Is it like this?
