  • So ...need a bit of direction-was carbs, not coil pick up

    ... causing bogging. Battery responsible for tach problem
    So after replacing the battery my tach works fine now. HOWEVER as I had mentioned a bogging problem previously and was pointed towards the coil pick up as having a broken wire. Nope.
    I was unable to find a broken wire that when I pulled on it the bike would/should die. Gave up on trying to find that and put it back together. BUT WHAT I DID find was after bringing it back after a very short ride before it started to bog again was returning two hours later I found a LARGE SPOT where fuel had been leaking which ran into and leaked out of of the air box.
    So I removed the airbox and the carbs.
    I spent a ****load of time trying to troubleshoot the tach and the bogging. Hoping some whiz with these things can point me in the right direction rather than another Snipe hunt.
    Thanks.

      If there is fuel in airbox, then the float valve(s) in the carb bowl(s) are not sealing, causing an over-rich condition.

        That there was. Twice. First time I thought I had flipped petcock incorrectly. THis time there wasn't a question as they were just at "ON" as I have always run my bike and I could see the drip and the fuel stain on the garage floor.
        Might I ask you what you'd suggest to cure that? The repair?
        TIA

            Deebs nailed it on the best way to check float height, this will give you a no nonsense view on exactly where that float is sitting.

              Eek!!! ( ⁰д⁰)

              Iffin the fuel overflowed outta the carbs to the point where's it went backwards into the airbox (which on MY Special is actually uphill from the carbs even tho's the bike is on the centerstand and on level ground...) ╭(°ロ° ”)╯

              Then it's wurth'a look see into yur engine oil to find out if and how much fuel made it into the engine as on my bike the intake booties and inlets are downhill/downstream of "overflowing" carbz. ( º﹃º )

              Well.... (O_o)

              U N L E S S you do wut I do which is put a 2x4 under the front wheel every time I park the bike overnite on the centerstand. (๑•́ ₃ •̀๑)

              Allz bets are off iffin you only use the sidestand.... (´・_・`)

                FWIW....꒰(・‿・)꒱

                The carbs pictured in the "Carb Pagoda" ain't held up to the crossbeam by magic oAr magnets. (⇀‸↼‶)⊃━☆゚.*・。゚

                I used reg'lar ole bailing wire but where's it threads thru the carbs/bracket Kan't be seen cuz it's behind the yellow tygon fuel lines/filterz. (⊙ᴗ⊙)

                Now-a-dayz I've upgraded to usin' these thingies bought at Lowes Hardware section....

                A bit mOaR secure/safer than bailing wire as each time you Test and find the level(s) ain't wheres you need'em to be? (o_O)

                You gotta drain the bowls and flip the carb bank upside down (again...) to measure/adjust the float tab(s). (_Oo)

                The large hose clamps just wurky better. (^_^)
