My brother has a 1979 yamaha xs400 it ran really good then while he was letting it warm up it died then he restarted it and it died again and hasnt ran since. It is getting gas the spark though is kinda reddish color. I check it is in time. And it doesnt have points it has a pickup so i have ruled points out. I just cant see both coils being bad at the same time but i may be wrong. Hopefully some of you guys can point me in the right direction. thanks

I thought about loosening the banjo bolt on the side of the cylinder and run the bike a bit to make sure its oiling using a prmix gas right now.

Probably no need to adjust the pump but how does the bleeder work?

Anyone have the manual for the at3 I got this thing a few weeks ago i know it runs but do not know about oiler yet was unhooked doesnt look like for long though it has a plastic wheel on the side that appears to be an adjuster thanks
