okay, here's the background. my cousin bought a '78 GL1000. a couple weeks ago. we are putting it back together. carbs were off when we bought it and most of the wiring was in a box. the guy said he had the carbs apart and cleaned them. i pulled a bowl cover off to look and it was almost spotless in there. now it wont start. we have good spark on all four. pretty much eveything is plugged back in i believe. we replaced the tank and we are getting fuel. (even tried spraying carb cleaner in as starter fluid). no fire, not even once. just cranks over. i put timing belts on it, but i doubled checked and they are timed right. anything else that i may have missed? any help is appreciated...
thanks,
kyle
