    bottom end?

    my 1980 gs 750 idles well and doesnt sputter or anything like that. Any engine speed below like 3000 rpms, the engine doesnt have power. getting it moving on a hill is a nightmare, and after 3000 rpm, the bike takes off. i ordered a carb rebuild kit (4), what else could it be? My petcock is shot so i just put it on prime and added a inline valve. I dont think thats the cause because it idles well, and top end is great. So im thinkin jetting, or a kink in the fuel line, or a dirty jetting circuit?

    or could it be because im running all 1/4 inch fuel lines? except the vacuum line.

        Clean the carbs thoroughly, then we'll talk.
