im having a problem with backfireing upon deceleration ive had alot of issues with the main curcuit Red/white wires with dirty connections it would barely run wouldnt idle before backfiring through the carb and dieing i cleaned the connection at the run/kill switch plug, cleaned up the main fuse spot and the three wire plug im pretty sure goes to the fuel pump and it runs fine now but backfires on decel just wondering if theres any other connections that would cause this or would it be something else

also i have a k & n air filter and moddified stock exhause with 1.5" pipe welded on end cap and original pipe cut off and welded over hole......it also dropped down to -20c today would those three things lean it out that much i dont remember this happening last winter

any help would be appreciated and any other electrical contacts being dirty attribute to this???
