    acting weird.. for lack of a better term

    ok for those who havent been following along lol

    80 gs850gt

    new accel coils & relay mod
    valve clearances good
    new intake boots & o-rings
    airbox sealed
    carbs dipped & synced
    tried the color tune to no avale did the rpm method to get the mix

    well its been ok lately so i decided to take the bike to work 20 mile trip its been good so why not. well warmed up good for about 20mins since it was in the upper 20's. got out of the driveway and the rpm's dropped after a block. i have the idle set at about 1200 it went down to about 800-1000ish when i pulled the clutch in at a stop sign or red light. a few times while on the highway when i pulled in the clutch at a light it stalled out about 5 TIMES! well on the return trip it only stalled one time but sometimes at a light the rpm's jumped to almost 3000 then after about 15mins of that the rpm's drop down again. when i finally got it home the headers on 1&2 were warm and 3&4 you can cook dinner on. the plugs on 1&2 looked a wetish brown (rich?) and 3&4 looked light tan-whiteish (lean?). no spots or heavy wear on the electrodes. there was a total lack of power in 3rd+. on straight highway i was in 4th throttle all the way out and not going above 5000 and sounded hollow like not fireing on all 4. in 1st sounded ok till about 6000. 2nd it started to sound more hollow with intermittent power. but able to climb a hill no problem cant do it in 4th or 5th. i was able to climb a hill in 5th last week....


    anyway i leaned out 1&2 and crossing my fingers. any other ideas are welcomed

    Sorry but you are going to have to clean those carbs again.

    I ran into a similar situation with freshly cleaned carbs on my Katana that had sat unused (but on the bike and filled with fuel) for about 4 months. The bike was hard to start, the idle went all over the place and 2 cylinders weren't firing properly. A fresh strip, dip and rebuild sorted it.

    Good luck with it.
    Cheers,

        One: have you checked your tank? Rust/dirt will make it's way past the screen. Tiny but enough will clog things up.
        Two: did you replace the air filter and or weather stripping in the air box? Broken down foam filters or sealer strip will get into your carbs

        Three: you're positive the ignition timing is correct? What ohm coils did you purchase? Checked to see that your ignitor isn't bad?

          1 - tank is clean and im dipping the carbs. why not dosent take long and certainly wont hurt anything

          2 - air filter is new oiled LIGHTLY, box is resealed

          3 - 3ohm rated accel super coils, igniter new/used from matchless i think thats who i got them from. i have a couple from him so i may switch it out just to be on the safe side. i have yet to recheck the timing as of late. may just switch out to a dyna-s in the near future just to stop that sort of headache

            How long is "not long"?

            In other words, how long did you soak the carbs the first time, how long are you soaking them this time?

              When you clenaed the carbs did you just use new boot 0-rings or did you replace all the tiny o-rings inside the carb bodies.?

              you can at least draina bowl and check for any crud coming out that may be blocking things up.

                dipping them for about 8hrs each they were pretty clean from the last time. if one still looks gummy or dull, naturally it will soak for longer. blowing out and picking at all the cavity's and crevices.

                i only change the intake boot rings when i remove the boots. like if they are hard, cracking or sat for a long time. i took apart the carbs so all the fuel connectors & T's, needle valve seat, float bowl plugs, fuel screw. i replace all the o-rings and start with fresh rubber to maintain good seals
