ok heres the deal. picked up a bike, motor is ok, but needed assembly and such. I couldnt get it to start and i drained 2 batteries cranking and cranking. anyways. heres what i found and let me know what to check!

air, passags are not blocked... so thats fine

fuel, fuel pump is pumping, float bowls have fuel in them. Soaked a set of plugs as well... took em all out and all were wet..

spark.. heres what i found. when removing the wires, the number 2 cylinder wire separated from the boot and looked kinda cracked. one of the coils had the positive and negative wires reversed. so i replaced the plugs with new ones, replaced wires with ones from my old bike as well as the coils.

i tried starting after that with a little starting fluid and it ran and shit was flying out the carbs (fuel). flooded with a dead battery maybe? I was crankin for a long time before the plug/wire/coil change. Think i should just wait it out and charge the battery and try it again in the morning? I got it on the charger right now. oh, i sprayed starting fluid in it before and i wouldnt ignite at all. this was with the reversed wires on the coil and probs fouled plugs. then when fresh, it stumbled for a few seconds before it died. open the throttle and it died as well.

I dunno, thats the deal and im like lost. i think i described it pretty well, but help me out and let me know if u need any more info. thanks!

The history of the bike is unknown, so I would remove the carbs and thoroughly inspect/clean them. Just because the fuel bowls have fuel in them does not mean the other carburetor passages are clean.

Furthermore, you should test the ignition system to make sure that each spark plug is firing. You can do this by removing each spark plug from the engine but not disconnecting its wire. Then ground the side electrode of the spark plug against the engine and crank the engine using the starter. You should see bright sparks from each plug.

Please write chronologically in the future for improved readability.

sorry about that, just got thoughts all over the place.

The plugs are sparking, I checked.
The carbs are off my other bike which was running before. thing was the frame cracked and had some electrocal problems among other things, so i got the other frame/motor and started assembling.

Sounds like you've got the problem isolated... The reversed coil wires and the bad plug wire...

Charge the battery and give it a shot again later... You may need to have the carbs balanced...

Check out vacuum leaks if you can... that may be a factor in it running like crap...

good luck
