backfiring...not what you'd think.
10/08/10 at 22:33:28
Last few days I'll get a nice solid pop
when I start it up
. My shutdown backfiring is essentially cured excepting extreme changes in temp from day to night (open air filter). Any ideas? Idles just like always. Run's just fine. No loss of power, no stuttering, no smells or smoke etc etc. Everythings normal except for the start up.
I DID just clean and re-oil my KN filter. Maybe went overboard with the oil?

I think you might have over-oiled...
wash it out and try again...

I get a pop on startup every so often.
stock filter, stock 88 carb
won't start if I touch the throttle.
on the '96 if it didn't start on the second rev I could open the throttle a little and it would start.

How did you cure the shut-off backfiring? I have that problem, but only after it's bee b ridden, not after only idling.

You got your idle mixture a little bit lean.
turn the screw about an 1/8 turn CCW or till it poofs on shut off.

It smells like it's running rich. However, I have zero motorcycle experience, just cars. Do bikes naturally smell richer than cars?

In order to "afterfire", there has to be fuel (rich smell), some oxygen (fresh air) and an ignition source (hot pipe).
The last two are easy to come by even after a short ride. Fuel has to go thru a gantlet to accumulate in the muf. A lean adjustment makes this easy as when the engine misfires due to insufficient fuel mixture it passes thru and collects in the muf.
naturally an overly rich idle mixture will do the same thing.

I may be WAAAY wrong, but this is my second Fall with the Savage. Been through one winter. Our humidity is low and temps are 50 morning 82 daily. I have noticed a start up pop ocassionally. I also have a little more trouble with the petcock in winter riding. (40 Degrees) I just ignore most symptoms unless they seem life threatening to my engine. I am also showing signs of wear and get the grumble pops on waking up in the morning. Some of these "problems" described may be weather or temp related. We have to tune our engines for optimal riding in all weather. When weather changes our bikes are slightly out of tune.???

Back to BurnPgh's original thougth.
I have noticed mine doing the same thing a few times when I started it first thing. I have not done anything to the bike lately, my thoughts were it had to do with the changes in humidity, temp and so forth. i was relly hoping someone would have come up with something.
I don't think it is hurting anything, at least not that I can notice.
