were not sure. raise it just a tad, to around 1500 or so. would sound good to me, maybe 1600, using the idle adjuster. if it starts to act weird. then somethings messed up. then adjsut the mixture screw, in and out. for the highest rpms. then lower the rpms back to stock idle. 1500 maybe or so rpms. or 1400. actually i heard the manauuls 1700 rpms idle speed is kinda high. so back to 1400 or something that runs would be good. then check it give it gas. why it quit? maybe its not mixed right the screw has to be turned near the area to run right.

wait, warm it up before you do that.
first.

just raise your idle to about 1400 or so rpms and let it sit, blip it everyonce ina while. after around 5 mintues or maybe 10. then raise your idle with the adjustment, a tad, like to around 1650 or something, something high,idleing. and then adjust the mixture screw for the highest idle rpm. then. if it gets real high, and its still going, lower the idle back with the adjuster. to around the 1650 or so mark. then once youve got the highest idle set. remember how many turns it is. then lower yoru idle back down to 1400 or so. wherever its running good at. then check the blipping.

I think I solved it, found an air leak, check it out:

that bolt should be sealed though. unless the manifolds cracked. air going over. see if its in the manifold.

I put a piece of duct tape on it. It's warming up right now, I'm going to try and tune it again in 10 minutes.

by the way, the reason it only happened on throttle was because the pressure applied from the throttle moved the intake and exposed the crack.

Great! I always said many times way early in this thread that you had an air leak. And you did mention about the crack but you said it did not appear to be leaking there so we discounted that. I sure hope that is it and by all means put up a video so we can see if it is running much better and can handle low idle.
GOOD JOB BRO it took a while but some things are not easy to find.

Before I start trying to tune it today, I have a quick question about one of the hoses I replaced. I made a short vid so you could see what I'm asking, but the question is does the big hose from the bottom of the intake manifold going to the black round thing need a coupler?

i dont know. goes to a black canister from the intake manifold? that coupler shouldnt be enough to restrict it any. as long as the hoses are the same size, and the coupler fits it.

I don't think its a big deal if the coupler is there or not,,I removed all my evap/emission crap.I only have one vac line from manifold to my fuel pump,,before that when I was running a manual petcock I plugged them all!
If that line was a breather from the valve cover I would put it a little higher than the head and run a nice little filter on the end of it,,but it looks like an emission/evap line to me..

My attempts at starting today:
After running for about two minutes it stalled.

youve got the idea now. you might have to replace the intake manifold. ive seen cheaper on ebay prices. if its leaking.
if you kept raising the idle screw to get it started,after you did at the beginning, when it turned on, at about 1000 rpm, then it probably would of started up at about 2200 rpms, if you continued to turn that screw in more. i didnt watch, i was doing something here. .. after about 3 minutes at 2200 rpm, it probably shut off the auto choke. maybe try to restart, see what rpms it goes to.
then do a mixture screw adjustment. make the idle high, around 1700 1800 rpms, around there. then turn mix screw for highest idle rpm. if it jumps up high while your doing it, like around 2000 or something lower the rpoms back down with the idle screw. to around 1700 or 1800. then continue to mess with the mixture screw. then once youve got the highest rpms at the idle you set it at, a high idle 1800 or something, then lower the rpms back down to a normal idle rpm. maybe 1500 1600 or something whatever. i think the book usually picks a high idle rpm speed. 1500's usually good.
and there you go. theres minor adjustments after that. like blipping the throttle back and making small adjustments to the mixture screw for best running.
now. after youve set your mixture screw and lowered the idle back down to a normal idle rpm, check how many turns out the mixture screw is set at.
if its between like 1 1/4 to 3 1/2 your good you got the right pilot. if your around 3 1/2 or 1 1/4 you might need to adjust the pilot jet. but you should be good. 3 1/2 turns or more out, the pilots rich, if its 1 1/4 or under turns out, the pilots lean.
if you find your pilots lean, then you might have that air leak. since your bikes stock and the stock jets are in it, and you got the stock jetting. so thats it.
