That's where the needle stops ain't it? Think I've been to 11 or 12k, tad above redline anyway, shows no sign of peaking out. Too hard to be looking around when the road is that fast.

There's the enrichment circuit (choke/cold starting), pilot jet (idle to 2000rpm), and main jet (2000rpm to 14k). Just seafoam sitting in the bowls won't help those.

roadpouring I don't know if it's a reason for your bike not running but the oil level should be nearly to the top of the sight glass. There's a horizontal mark there.

I wouldn't run one with low oil.

Stvz11 Still working at getting this thing running. I’ve tried everything and am almost there but I still can get it running.

Fresh Oil...check
New Plugs...check
New Battery...check
New Air Filters...check
Fresh Fuel...check
Seafoam soakerd carbs...check

I’m to the point where the bike fires for a second or two then dies. If I try to fire it up again it won’t but if I let it sit for a minute or two it will do the same thing again.

Any thoughts on where too next? I’m so close but still not running. I do see the oil level is a bit low. It’s at the very bottom of the sight glass. Not sure if the bike has it or not, but Could this be killing the engine before I even get to see it run. Vac line and fuel lines seem to be good. Fuel is flowing through carbs when pulling vac on petcock line so I don’t think it’s a fuel delivery issue. Carb seems to be clean even when I drained it for the first time. Plugs are dry so I don’t think it’s flooding. I currently have the air filters off the bike while i was investigating. I’m trying to start it with they off and I do hear a poof of air. I didn’t think it was necessary to have them on to start it but correct me if I am wrong.

I’m at a loss right now...what are some of your thoughts?

This would be awesome if I could figure out who it is. If he has experience with a carb clean, I’d pay him to sit there and tell me what needs to be done!

You can use a small or right-angle screwdriver to get the float bowls off and get to the pilot jets to replace.

Even though the pilot jets may be the whole problem, they could also be a PART of the problem, with some of the carb passages are gummed up. Get a couple quotes from shops if you don't feel comfortable doing so, but honestly the carbs aren't that difficult, and it's a satisfying job if you like that kinda stuff. No matter what way you approach it, it's a difficult job, but I reckon it's somewhat of a rite of passage around here. We've ALL had to deal with the carbs at some point, myself included.

BTW where do you live?
