i have a mongoose 50cc atv stretched 12in and i put a tractor nose and fenders, and dual exhaust on it , and didn't touch any of the wires exept for unplugging the tail lights i put everything back together and and it runs but about 1/4 throttle it wants to bog and the rpms arnt high enough for the clutch to engage and it wont move i have tried adjusting the carb and everything i dont know what to do can any one help me ?

 

Was wondering out of you figures out the issue mine is doing the same I changed plugs and looked over wiring still same thing also do you know what the wiring thing is on top of the carb I ungluged it and didn'take a difference but there was lite votage going to it

 

Was wondering if you got the issue fixedine is doing the same

 

Adam165, your fault seems like the symptoms of a blocked jet in the carb, clean the carb out first. If the bike has an electric choke, the wire going to the top of the carb will be for it. The original posting could be a blocked jet, but a special exhaust can require the carb to be re-jetted.

 

Ya Iam thinking it's the eliteic choke system and its probly stuck open is there any way to by pass it or manually close it?

 

No. Clean the carb out. If it was the choke it would either be bad to start cold or run badly hot.

 

Cleaned carb any all jets still same some told me might be weak on compression but don't think so cause it idles fine just shitty on picking up rpms

 

Check the colour of the plug nose, white is weak, black and sooty rich. Change the plug anyway, check the air filter, adjust the valve clearances, unlikely to be them but make sure everything is right. If there was water in the float bowl when you cleaned the carb, some more may have come in from the tank so clean the carb again. A faulty CDI can cause this problem but check everything else first.

 

"some one told me it might be weak on compression, but I don't think so cause it idles fine. Just shitty on picking up rpms "
It still could be compression.
Got a spark arrester plugged with goo?
