Re-assembled '86 GSX400e won't start

[matrox02]

Hey All, I pulled apart my 1986 gsx 400e for the frame to be redone, I have finally got it to the point where it should just be turn key and ride however, with a brand new battery and new spark plugs it just cranks but never starts, with choke on it back fires ( and really loudly ) I put some starting fluid down the airbox incase the 4 week old fuel is stale but no go, still just pops and back fires, So i have fuel, and i have spark, and i havnt touched the timing, but now it refuses to start even with some start ya bastard, I have swapped the leads on the coils and that made no differance either...so a bit stumped?? the battery is on charge again, but its literally only a few days old

My guess is you have your leads on wrong plugs

Well low and behold... it ran with the plugs the other way around... dont know why it popped and farted and carried on like it did yesterday with the coil inputs switched, though yesterday i didnt have new plugs.. Thanks for the Help otherwise
