"... the backfire issue only started after I made the carb adjustment..."
That would have helped, but I do not chase my tail when it comes to 14.7 vs Who's faster in?
"... I have since reset the carb a couple of times but the problem is I cant get it to idle at all..."
This be the net speak and who knows what else you didn't bring in kind of run around guessing what you did last and now this.
"I set the idle at 1000, it runs for a minute or 2 then drops off and stalls the engine..."
I see I am going to run out of gas or someone is beating it to the punch... is it 14.7 or gas entering sooner? Sounds like spark is there, gas is too, but loss of gas at idle? Where is the fight for the rush at the door?
"... the bike runs strong other than the idle issue so I dont believe its the cam sensor again or it would show up in hard running for sure. Ive never had this particular issue before..."
And that's the fun part on this side of the screen, an on your side... 'Very frustrating.' Yeah, if only I could spray WD-40 from here before it becomes page 32.
"... The idle adjustment screw is really finicky, barely make it move and it jumped to 1500-1700 in an instant.[/quote]
I could be completely off base on this, but sure sounds like, sniffs like, can't tell for sure sitting here with a new flip style spray tube.
"... I think something is going on in the idle circuit, maybe needs new idle needle?"
Pull it out and see. If it has a deep groove up the V of the needle, carb body is junk. Again, I can only be wrong every step is just guess at it and say... 'well it was fine all this time before I touched the carb and that idled like perfect?" That's my info I have is that assumption of the forensics. Can't be a bad needle unless you gorilla'd the needle tip going back and forth I have no clue? Beats me if you damaged finding idle that was not in need of who knows what mystery lurks?
Low/Main/Idle screw = Full Idle circuits are open. Bike Has To:
a. Starts and idles instantly. Choke on choke off it starts and even the choke starts it faster cold is that circuit is open too.
b. If applies, that squirt at the accel pump a few times starts and stalls all day are a bunch of circuits clogged, if not one only.
c. Idle screw is to lift the slide higher or open the butterfly under the jet hole openings. Has nothing to do with jetting per say. It would just idle faster and hang there.
Bike before After:
I choose my threads carefully because who cares, it's not the new sensor if you ran all day up to that thermo-zone and it cuts out so it's not ignition, unless you touched that in the cone? Say no so we are back to who feeds whom? You never touched the ign system is the guess.
Look at the plugs. Starting to blacken up or whiten up? There is no complaint about performance, but this low vac pull to who enters sooner? My guess is you moved gas with the needle move. My guess is who enters faster? Did gas override an air leak? Who entered the speed event sooner this time 1500+?
No matter how you think more air enters the chamber, you have to think on the valve's close; nature goes right back to 14.7. I just think magnetic is nature and that in motion and all that is the piston eventually stops at bottom dead center is dead right there = 14.7 is filled with who entered sooner... case closed or valve closed, whoever is sooner LOL.
And DATA is the output with limited input.
