    Default Shop Recommendation

    Good Morning Everyone!

    I have a 2005 Yamaha VStar 650 Classic and I need to find a good reputable shop to check out what is still wrong with my carburetor. My bike was sitting outside covered up for three years before I purchased from a friend. He did not take care of it and left 1/2 tank of gas in it. I fixed what I could so far:
    1) Drained tank from the bad gas
    2) Replaced fuel lines, petcock, fuel filter
    3) Changed Final Drive oil and regular oil and filter
    4) Removed Carburetor, cleaned and blew out the jets
    5) Replaced Spark Plugs

    Symptoms now:
    Starting full choke; pushing in choke killed bike prior to cleaning and replacing items. Now it runs but in order to keep it alive I had to adjust throttle idle screw. I adjusted the fuel mix screw but the problem now is one piston (closest to seat) runs lean (white tip spark plug) and front piston runs rich (black/brown spark plug). I'm pretty sure the carbs need to be synced but when throttling it does not go down to idle but lags back down. Additionally, when idling on or off choke the rear piston pipe runs red hot, might be attributed to it running lean on this piston.

    What I need shop to do:
    Investigate or diagnose issue so I can focus money on appropriate repairs and/or sync the carbs. I have Vance and Hines after market pipes but the previous owner did not change the jets to match the after market pipes, so there might be an air flow issue.


    I realize I typed a lot of information, any suggestions would be appreciated!

    Respectfully,

    Matt

    What that guy said - I sync my carbs fairly regularly since I like to tinker with jetting for season changes. Mine do seem to drift a bit.

    And one (if not more than one) of our pilots is plugged. Just buy new pilots? Cheap fix for the non-idle issues. On my twin (KTM 950 Adventure) the front piston is know to run cooler. I run one main jet larger in the rear piston to cool it. Also check your carb to cyclinder connection. If you have an air leak that could make it lean too.
