Loud POPING Sound under fuel Tank

Sounds like CLASSIC intake spit-back. You may need to retard ignition.

Thanks Mate,
I am looking into tune boy or something like that to start learning more and looking at what the engine is up too.
 
I tables.

How much and which cells? - That's going to be a bit of trial and error.

If in doubt I always compare a different tune - esp if you have an old one that was OK in the area you want to work on.
 
Well i got my cable (Finally), I got three from china. Now I just gotta Learn how to use it!!!!!!
