I rode it up and down the street a few times and here's what I have.

1. Starts first kick and idles fine (not a problem before) which is frickin' great!

2. Doesn't die down until the airscrew is about 1/4 from bottoming.

3. Ran really clean on bottom with the 55 but now has some br-br-br-br before it cleans out with the 48.

4. Adjusted the airscrew until it was a tad more than 1/4 out and it ran better but still some br-br-br.

I'm thinking that the 48 is too much and I need to go up to a 50 or 52.

Your thoughts? Again, thank you all for all of the help! :D

I opened it up to 2 turns out and it's still doing it. :cry: I'll get some fresh gas and try it tomorrow. Not sure how long that shit's been in there.

always tune with fresh gas of the same oil mix as you plan to run everyday. I haven't worked too hard on getting my gen-4 perfect becasue I'm still burning off my old race gas for my dunes bike. when I finish it off and get the exact pump gas I plan to run it on everyday, I will get it perfect.

Good advice Danny. I'm a bit of a dumb ass for even messing with it with the gas that's in it. :bash:
