I bought 2 trikes in pieces. An 86 and an 87 250sx. I have the 86 mostly back together. I'm doing a semi restore just removing rust and painting parts and fixing the mechanical stuff. I did the entire top end. New rings, gaskets, lapped the valves and adjusted them. Totally went through the carbs with all new jets and gaskets from 223cycles but the 86 came with an 85 carb which I don't imagine is a big deal. The wiring harness is a bit rough but I have what looks like good spark. I'm getting fuel to the cylinder I have the throttle and choke hooked up. Exhaust is on but it just will not fire. The starter is bad so I'm turning it over with a drill and when I open the throttle up it turns over quite a bit harder. It won't even cough with starting fluid. I'm stumped.
