Boggs out above idle

Ok guys, scooters arent realy my thing but i have alot of experience with two stroke motorcycles and watercrafts. So here is my problem. I have a mini chopper frame w/ a 87 elite 50 motor welded to the back of it. The wiring is a mess, there is no air box (one of my problems). It starts fine and idles great. But as soon as you go to give it any gas it bogs but continues to run but doesnt realy gain any rpm's. It allmost sounds like a rev-limiter (could be elecrical problem) but all i am wanting to know is were to start looking for problems. I will get some pictures up here so you can see what i have to work with.

i stated that was one of my problems, I know it is lean but what are my options to fattening it up since i dont have the factory airbox. Mabe a click or two on the needle height?

these are pics from before i attempted to get it running. All the oil pump lines are now hooked up (allthough im premixing) Have you guys ever just blocked the oil pump off?

as i said earlier it is a mess. But i raised the needle one notch to try and ritchen it up....didnt change a thing. I am leaning more towards electrical because when you block the carb off with your hand nothing changes. Does anyone know the ngk plug number for this thing? It has a br7es in it now and i highley doubt thats the right plug. I run that in my 125 motocrosser.

NGK BPR6HS is the plug. have to say, that engines kick a** cause i have one on my spree.

try propping the motor up so its level cause that could be messing with the carb. And your bystarter isnt hooked up so its always in choke mode.

Dude...

It won't run without some sort of airbox/airtube.

If you put a pod filter on the carb directly, you will need to enlarge the main jet. For a Spree, this is a #65 -> #85 jet jump. Playing with the needle valve won't cut it.

I found that a pod filter stuck to the end of the intake rubber (for the Spree) works fine with stock jetting. Assuming you have that part. Getting the length of the intake right seems to be the key.

one problem there the wires have been cut right at the terminals. Im going to try soldering to them though. Is it pretty much jusr a 12 volt solenoid?

yep hook it to the stator so when the engine starts it will receive power.
