2002 XR 80 trottle lag

[notiller]

Hi everyone iam new here so bear with me.

I bought a 2002 XR 80 today and when i got it home
i noticed the motor would die when you threw the trottle
wide open real fast.
Works fine if you do it at a normal speed.
Whats wrong is the carb.

Thanks

May be a lean main jet. I've seen this with a 2003 xr 100.

That is normal for a 4stroke with a standard carb. You may be able to improve it a little bit with jetting changes but for the most part it is normal.
