Kindof a two part stumper here. When i bought the bike it ran rough at idle. Dont have much experience with carbs but i figured itd be a simple rebuild job. I pulled the carb and took a look inside and it looks pristine, no gunk or deposit build up. Jets are all clear and all four diaphragms glide nice up and down. Next i looked at coils. They all tested fine and it isnt missing(replaced the plugs, the old ones werent so bad either). Still runs rough. Now to part two. When i bought it there was a small pinhole leak on the tank but it came with an extra so i cleaned it and swapped em. Now i can ride it for about five minutes and i lose all power as it slowly dies till the rpms hit zero. No response from giving it throttle during this. But it will sometimes jump and want to run as its dying. Then once i pull over ill have to wait 5-10 mins before itl fire right up amd run for another 5-10 mins. This was not an issue until i switched tanks. It is the same fuel pump. My only thought as of now is faulty fuel pump causing both problems?
