    1980 CB750

    Just started my first cafe project today and all ready ran into some trouble. LOL I saw the bike this morning and it was running when I got there. The bike looked and sounded great, it had no major problems with it. A couple hours later when I got it into the garage, we went to start it up again and got no where. Put some fresh fuel in, worked the choke, and nothing but a few backfires. Are there any tips or special techniques to starting these bikes?

    More than once I forgot to turn on my fuel valve. Did the valve on yours get turned off?

    As in the PO didn't start it in front of you?

    If so the pilot jets are plugged. He probably shot it w/starting fluid or bump started before you got there.

    This might be too obvious of a response, but did you call the PO yet and talk to him, he knows more about the bike than anyone here. Good luck.

    my thoughts exactly; was it you who took the cover off the airbox or did you bring it home like that? screams starter fluid coax!

    When I got there, the bike was not running but already warm so when he went to crank it, it started right up. When I posted this up yesterday, I did call him and supposedly all he did was put jumper cables on it (which I did also) and choked it. And I know that he did not bump the bike because it was POURING rain all morning and when I got there, the bike was still bone dry.

    The cover was not off when I got there, that was me that took it off.

    And as for the dirt bike, its a 1978 Yamaha DT250

    Need a little help figuring out what is going on with the bike while I'm trying to start it. We had the bike running for about 10mins, and then it just cut-out on us. I've posted a sound clip of what it now sounds like when I try to get it running. Any thoughts?
