ok. so i upjetted to a 98. the bike was pretty much cutting out to even go, i tried having my fuel mix screw at a 3 1/2 turns out like before but done the same thing. i revved it up a little and got it going and went for a ride. seems boggy at 20mph. then like at 35mph flattening out at the top of the hill, it falls flat on its face. not a fuel problem. it cut out like it did before. i let off the throttle, and it idled back fine.
i came back and messed with the fuel mix screw some more but 4 turns out and it kind of doesnt cut out. really dead speed around 20mph. i use 1000 rpm koso contra spring and my roller weights sliders are 6.5grams. my top speed last time i was out got to around 50mph. any suggestions? should i up the pilot jet now? then try my runs? im at 37, i have 38, 40,42,..

heres the 37 pilot jet now, and a 98 pilot jet, idle and a little trip to show how it has no power around 20 on up, unless it really gets goign but it takes hills to make it go. vid.me/WFwh

not one comment on the screw position huh? what am i supposed to do about that?
well, one honda elite sr 2001 with paperwork, no motor find one that works FOR SALE. screw this. i dont keep upping my pilot jet to 60 and it still cut out and no matter what main jet i stick in it it runs like shit like itis. was pressure tested.
lots of parts
no tips on the screw or comments? i dont know whwat to do here. it runs like crap past 20mph. ive tried every combination of everythig I have every single thing to try with it. i have 3 other carburetors. the stock one ran like crap.
cant you get these side flash bars out of the way i dont know whwere my cursor is. i dont need to see tht all the time i know where its at. i have every combination of everything to try for it, and ive tried it. i have 3 carbs, even stock farts out on me.
i just tried upping the pilot jet to a 40. still cuts from 1 1/2 up to 4 turns out, until i rode it down the road and back, then i retested it, it cut out until i got to a 3 turns out, then it wont actually die. but when i took it down the road, with the screw at 4 turns out, it died on me again. no much faster than 35mph.
any other suggestions. any comments on my screw position. if anyone gives me a good deal on an elite with the original papers, its yours. im in kentucky. no i wont take a bag of grass or your moms prescription labelled with the cops tracking device on it for it either. no i wont take hundred bucks get off my land. now.

i dont know what to do with the screw. should i just leave it at 1 turn out, even though it cuts out? should i set it to 3 or what? should i get it to kind of not cut out? is the cutting out from? it? or whatever it or whatever it controls

There's a reason I didn't mention the mixture screw.... because I wouldn't be concerned with it until I had gone through the process to find the best main jet. The mix screw is not how you tune high throttle openings, that's what the main jet is for. Don't touch anything else in the carb and do WOT passes. Record the results. You will see some sort of pattern. If you go fiddling with other parts of the carb, then it may screw up the results you get with main jet tuning. With pretty much any kind of tuning it's important to only change 1 thing at a time. Otherwise you may make the process harder than it needs to be.

thats why im asking. i want someone else to fix my tuning. ive tried with this thing. as i said, i guess my 95 main jet done me the best, but my cht was at the 374 like hte post i said before about it. once i upped my main jet further beyond that, which im not sure where my main jet should be at, 92, 95 i guess 95 seems.. good. once i upped to the 98 becuase of temps, and from my stock carburetor, and the free flow air filter, plus the free flow exhaust, type combination, 95 sounds about, right to me, once to a 98 though becuase of my too hot cht gauge, i started to cut out again. heres my last video again, vid.me/WFwh

i guess im looking for someone to tell me when its, tuned. what theyd call it tuned, so i can ask questions, cause i dont know wtf im doing, since ive never tuned a carb.
like i was saying, once past the 95 main jet, the scooter starting cutting out worse than it did at first. when i moved up to the 100 main jet, it would absolutely not stop from cutting out when i revved it back. i had to baby it. then when it did actually take off, when i held it wide open, it would like, do a complete bog. like the sound it does when i rev at idle, but it'd still idle until the bike, idles way down. like a lean hang or something i would guess. until it got below that, which by htat point the bike is almost stopped, if anyone knows what im talking about, it woudl then when it almost came to a stop, then, just the motor would die.
ill make videos of the jetting but if im not getting it someone, sort of help me, here. as i said it overheated, so i upped the jet to cool it down with more fuel. which led to the motor bogging out at full throttle and the idle cutting out way more.
after this i put a 40 pilot jet from the 37 in there, where it kept cutting out, and .. i dont really remember id have to go out and check it again on it.

Its just an opinion, but i do believe that you have a carb too big for you 50cc stock cylinder especially with that big "sponge bob" air filter. Having a garb too big will make you loose the venturi effect and the atomisation of the fuel. What you could try is this: restrict the air intake to create a high pressure of air going into the carb. Do this as close to the carb as you can. The higher air preasure should help you get a good flammable mixture.

Hope you kept the stock airbox.Ebay the 21mm carb and buy a new stocker.Mount it without tampering with it and connect it to the stock airbox,then get back to us.In the interim read everything you can on the operation of a carburator on an internal combustion engine.Pay special attention to how each "circuit" effects performance at appropriate throttle openings.

In your very first post you said:
....it woud hold 7ounds of air for like 3 minutes before itd go down to 4 from the 2 places i could block it off at but you could see the bubbles
It'll never run right until it holds air. And it doesn't hold air for three minutes and then start losing air like it's on a timer set for 3 minutes. IT HAS A LEAK. Until this is fixed then no suggestion here is going to help you.
Sorry to be so blunt but you MUST fix this issue. You will seize that motor if you don't.

after upping the pilot to a 42 on the dellorto, it runs without cutting out, anyy. the problem is i already tore the motor apart and put it back together. that was after tearing it apart before and it checked out. but i ran it and didnt put hte fan on it and overheated it, so i wanted to check and see if my problems where because of any trouble i done, maybe. i checked over the crankcase seals, and, no bubbles, no foam, really foamy soap i used. it would hold 7 pounds for a minute or 2. enough to check. the motor didnt foam anywhere, i checked the seals, and nothing. ive tore it apart and checked it already and put it back together. i dotn want to do it again. i checked everything and it looked good. the manifold and reed cage looked good to the case. i looked in the case and the seal i used, looked still there, was sitting all around the case. there isnt any sort of anythuign showing any leaks around the case halves. the seal looked still there, still good, i could see it squeezing into the case and a line around teh whole case. so everythign looked good. my paper gaskets i used for sealign the carb connection and exhaust flange leaked. thats where the air came out at.
still, not much power from 1/4 throttle on, so much really, but runs ok, up to around 3/4 and up. i put the 95 main jet back in it case it was the one that acted the best. and i have switched the pilot jet from 38 to 42. so my overheating might of acted different now. i didnt heat check it case i need to set the airbox up better so its not hanging. it was hitting my clutch and wore some on the plastic.
