i got an 83 xs 650 with all new electrics, electronic ignition. i feel like the problem with it not starting is in the carbs. it will fire with starting fluid or if i hold the throttle wide open. when it does start it will not rev up and clean itself out, and if i chop the throttle at all it dies. i've sprayed the carbs out with gumout and installed new jets, but still nothing. i haven't actually gone all the way and soaked it in carb cleaner. also, it was running fine until i got home and it started cutting out... i caosted into my garage. i have a new clean gas tank now, the old on was full of rusty scale that was almost like concrete in the bottom of the float bowls. i guess my question is about the diaphragm actuated slides, i figure that they should be opening whenever it does start and i don't think they are. also, has anyone ever installed a sety of mikuni round slides with any luck? they promise more throttle response, power, etc.. i kind of like the idea because they are more like what i'm used to on my motocross bikes. thanks for any help you all can offer... great web site.
