    I'm new today and I'm glad I found this site
    Four years ago I did a total restoration on an 85 VFR.
    New bearings, new 1.00 over pistons, pretty much anything that could be replaced was.
    It fired right of when I was done and ran really well
    Put less than a thousand mile on it and then it sat for over a year( my wife became ill and unfortunately passed away)
    I tried to start it six months ago and it would only run with the choke on and would die when I gave it throttle
    I figured it had to be gummed up carbs /tank etc.
    I sent the carbs to Billy in Texas for him to go through them. He rebuilt them originally.
    I cleaned the tank but there was really nothing nasty in it.
    While the carbs were away I did a fuel flow test and it was good.
    Here's where I need help /advice
    I put it back together and it did not fire
    Pulled the plugs and all four cylinders were soaking wet
    Removed the tank and dried the cylinders and pluds off .
    I hit the starter with what was in the bowls and it fired right off.
    Put the tank back on and the same damn thing wouldn't even fire, wet cylinders and plugs.
    I'm thinking some how the fuel pump is over supplying the float needles.
    Any thoughts or advice would be really appreciated.
    Sorry for the long winded post but I wanted to give as much info as I could.
    Regards, Terry

    First thing I would do before digging deeper...

    Drain the carbs. If you have a hanging aux tank you can fill the carbs with, as the carbs are filling, rap on the carb bodies/bowls with a screwdriver handle or piece of wood. Sounds like the floats might be extended and stuck.

    If you don't have a aux tank, jump the pump relay so it will prime when you turn the key on and tap the carbs while they are filling.

    I always do this on my bikes after storage and the carbs are dry.

    Don't think I've ever heard of our 35 year old pumps overwhelming properly rebuilt carbs.

    Anyway, this is easy to do and a place to start?

    Oh... and you have a VF1000R, not a VFR1000

    and... you missed your chance to post a pic on your first post. Can never get that back.

    :)

    Thanks for the input.
    Yes I do know I have a vf1000R .
    I will try aux tank but I would be really surprised if all four float needles are hanging up and I know my fuel pump theory is out there.
    You are right that most times the simple solutions are the correct ones.
    I'm just driving my self nuts working on it in the garage with this quarantine thing going on.
