i would say you have a stuck float.the first link talks about removing the ais.the ais injects air into the exhaust to keep fuel from collecting in the converters and causing them to overheat. with the cobra pipes you don't have cats.so you can remove the ais system.
the second link talks about the carbs. at the very bottom scroll down. it talks about removing the fuel shutoff selonoids.they are there to shut off the fuel in case of tip over....lot of guys remove them and it talks about putting in resistors to prevent the engine light from coming on.
you need to find out what jets are in it, with the cobras and if it was rejetted. read the section on tuning and jetting.
it's best to keep mukuni jets. mains should be 115 front and back, pilot 17.5. mukuni jet needle,pms set 2 turns out.you need to read the tuning section.. delphi and star bike forums are two good ones, i'm supprised you did'nt get help on delphi.
usuallt the pilot jets get dirty, blow them out and clean the side holes thoroughly some take the wire from a bread wrapper and clean the sideholes...
Yeah, unfortunately, as far as the taking this off doing a resistor for that, etc, i'd love to, but it's not my bike, and this guy is nickle and diming me to death as is. he'd never go for all of that stuff.. with that said, whoever put the pipes on did not rejet the carbs. they look to be the stock sizes. i.e. too small. but i have no idea how the bike runs, because it was brought to me broken. the idle air screws, one of them was turned out 2 twists, and the other was turned out about 3/4 of a turn. i'd assume because of the jetting. lol
as for cleaning them out, i almost always have carbs ultrasonic cleaned these days. i've had too many instances when i've taken them out, cleaned them, put them back together only to find that some tiny passageway the thickness of a human hair is still clogged. like on some Kiehin carbs. i don't think these mikunis have that issue though and i probably could get away with doing it myself. but, not taking any risks with this bike. if they don't look brand new, i'll catch flack and he will start "renegotiating"... i may actually have some mikuni jets laying around already in that size though, and if i do, i'll throw them on there during the reassembly. it couldn't hurt. but at least i know a good baseline now.. 115 and 17.5 ... but should the front vs the different be different? They are almost always half or 1 size difference on the majority of bikes due to the heat of the rear cylinder vs front.
as for delphi, i got one response from a man scalding me for not giving my life story before posting and properly introducing myself to the community. which... i guess i can understand, it's only polite, but, i'm not necessarily joining the club, i'm just, in a pinch on a bike i've never done this kind of work on. doesn't mean i'm inexperienced.. i've been working on bikes for years now, it's just that there are so many years makes and models of bikes, most of them EFI now, it's easy to get mixed up with an oddball bike now and then that does things totally different from other bikes (like running the cam chain off of a separate gear instead of from the drive shaft). With that said, i'll probably stick around here and answer some questions for people if i can. but i'm not a v-star owner.. just an unfortunate mechanic that got stuck with a rat's nest bike and didn't know what he was getting himself into... lol. win some / lose some...
speaking of cam chains and such.... this whole thing started with me changing a sprag clutch, and ultimately having to re-time the whole motor. which, i'm 95% sure is OK at this point.
but something i noticed when i initially tried to start it was, at closed throttle, it spun over just fine, but when i opened the throttle, it started kicking back and making a horrible clanking sound on the sprag clutch. i FIGURE this is because the carbs are clogged and keeping it from running, and it was kicking back against the sprag clutch when thinking about firing...
but... i'm also very very worried that the cheap ebay sprag clutch is...... a cheap ebay sprag clutch... you know??? i'd hate to have to replace that a second time, and worse off, i can't return that one because i had to alter the plate it sits in, in order to fit inside the groove on the flywheel.
any thoughts? i will know more once i get to fire it up after the carb clean but... do these bikes notoriously make noises in the sprag clutch area or anything? i'm looking for "naaahh you're fine!" by the way lol
