But isnt backfiring directly related to lean mixture?

Or rich.
Or intake leak.
Or exhaust leak.
Or tuned for performance. (POPs, not BANGs)

tuned for performance is on the very edge of being lean but not lean, tuned for durability is just a shade richer to keep the engine cooler

I was smelling gas with my pilot jet at 55.   I as also getting some big pops on shut off.  Like a .22 cal gun fire.  Popcorns popping on decel.  I changed the pilot to 52.5.  No more gas smell.  but still some loud pops and popcorns.  no leaks in exhaust and intake (double checked).

Can the gas smell be due to stock washer or spark plug not firing right?  too hot or too cold?

Sounds like it smelled gas with the 55 because you were suddenly idling way too rich. Did you ever try to go clockwise on the mixture screw to go leaner?

You know, I have kind of the same issue. I have the 55 pilot, no gas smell and no leaks but I cant get rid of backfiring once and for all. I just live with it, more noticeable because the muffler has no baffle now. In all, I cant seem to get the performance I want with the sound I want so I am stuck somewhere in between.

have you changed out the spark plug?  I am thinking it is not firing all the time.  Clymers manual's troubleshooting says that backfiring can be caused by bad or incorrect sparkplug. that is what I will be checking next.

Also, do you have washer mod done?

Yes, I did the 2 white spacer mod while I had the carb opened. I agree with you that my plug may be bad, especially messing with the mixture as I have been. If I must add though, taking the tank off to remove the plug is a crappy design, so far the only bad thing I found about this bike. Laziness so far prevented me to check the plug Smiley I'll have the shop replace it when my free maintenance is up.

This mod will allow access to spark plug without removing the tank.  Open the chrom cover like door.
