Has anyone experienced backfire during deceleration after removing smog equipment?

I never noticed the bike doing this before de-smog. All pipes removed and plugged as you guys have shown.

My guess is that I am sucking in air from somewhere. Possibly need a bigger plate to cover the port on the head? I fabricated a high temp gasket as well.

Cheers!

adjust your needle valve and faniggle with your air adjustment screw!  Needle valve clip adjustment worked for me! All this depends on how high above sea level you are !

There was a post 2-3 yrs ago that approached the de-smogging as NOT what to remove but what to SAVE.

It took the complicated procedure and make it so simple.

Basically it said "TAKE EVERYTHING OFF"

- Remove all the smog crap from under the gas tank and engine. You will end up with a large pile of stuff on the ground.
- now just add a line from the carb base to the petcock (plug the other carb base hole).
- Plug the large hole left in the rubber air inlet tube between the airbox and the carb.
- Run a piece of tubing from the gas tank vent down the front of the frame (I did it along side the clutch cable)
- Make a simple aluminum blank to cover the exhaust hole in the cylinder head.

I think you are pretty well done at that point.  ;)


Actually, read & re-read this whole thread a couple of times ..  I think all the info you need is in it.
Try not to look at what has to be removed but what stays - what stays is simple- The rest goes in the bag.

Just desmogged the bike today.  Most of the old photo links are broken which is a bummer but Papa Bear's break down was super helpful when it came time to make sure I had everything set up correctly.  I salvaged one of the old gaskets, cut the pipe, and used the metal from a tuna can to seal it up and it works great!  Gonna take it for a test drive but she fired right up when I was finished.  Happy winter riding everybody!
