Popping when decel

[AaronG]

I know it is doing this because of the pipes but what can I do to fix it and what is actually happening.  It only backfires when letting off at high rpm's.  Thanks.

You are running lean. It will backfire if you have an intake or exhaust leak too. Have you done the PAR blockoff yet?

Do a search for ...PAIR valve..or marble mod...

Take off the PAIR valve or do the marble mod.

The PAIR valve adds oxygen to the exhaust for cleaner emissions. When you mod the pipes, the PAIR valve causes backfires.

Thanks guys. I knew I could jump on here, go to bed, and have an answer in the morning. I will fix it up tonight.

For some reason I just got to thinking...who was the first guy that thought to stick a marble into a hose to fix a problem? When you think about it, it seems a little weird.

its the easier way to block the line instead of taking it off and finding something that is the same size to block the hole in the airbox.

Just do the Marble... It takes longer to pull and replace the seat and tank than it does to put the marble in.

You couldn't be more right. To bad everything isn't that easy.
