300EX starting and running issues

Hello,

I recently bought a 2001 300EX sportrax from a friend for $150. It was in quite a few pieces and hasn’t been run for a few years.

He said the only thing wrong was the rear carrier bearings, one was seized. The carrier was already removed so I pressed the old ones out and installed new one, reassembled the rear axle and moved on to putting everything else back on the bike.

Anyways, I don’t have the headlight or handlebar plastic so no key. I was trying to get it running and I just connected the ignition wires together and was not able to get the starter to kick with the start button. I am able to short the solenoid with a screwdriver and it kicks the starter on and I can get it to fire and run but it’s running rough, I took a quick video and will try to upload. It doesn’t idle and giving it too much throttle kills it also. The smoke is the paint, apparently he painted the exhaust, not sure what with but it’s burning off.

Any ideas on getting it running right also getting the starter button to work instead of using a screwdriver?
