I've had my 77 XS400 for a few years now. All i have ever done is drain the gas and put the battery on a trickle charger for the winter. I only use 90 or better no ethanol gas. this year i put fresh gas in and it took awhile, but she fired up and ran great...for three minutes. after that, it would not run. it would chug a little on the starter motor, but never catch and run.
this is my first bike and i never had any one to teach me, so what i know is from this site and you tube.
i took the carbs out and cleaned them step by step while watching a vid on the same carb, the only thing that i didnt touch were the fuel mix screws. i put it all back the way i found it. put in new air filters, rebuilt the petcock (it always leaked). I got fresh gas, she started up on the second kick, i have never even used the kick start, and ran great...for four minutes.
i have done this processes four times now and always get the same results. I know enough to adjust the choke and all, but the shroud of wizardry that encompasses most carbs is beyond me. I understand how they work, but i dont really know what to tune, so that's why i left all of that the same. I pulled the plugs, they were damp, not wet, and one was clean wile the other was black. and they had both spark tested well before i tried to start it.
basically i cleaned the carbs a lot, and nothing changed,
PLEASE HELP!!
