Hmm - question? Random backfiring?!
Hey guys,
I've got a question. I ride my bike EEEEEVERYDAY to work. And normally it runs pretty good. But yesterday as I started the bike up, it started up kinda weak. I didn't think much of it, I let it warm up for a minute then off I go. As I get on the road, the bike was popping/crackling/farting/backfiring quite a bit. I have my bike tuned to perfection and I have a hard time trying to get it to backfire at all normally. But for some reason, on the ride to work yesterday, it was doing all of the above and quite a bit. That is the 2nd time that it has happened since I've had the bike tuned (8 months ago). The first time was when I went on a toy run I believe it was, and the bike was getting reaaaaally hot since there were hundreds of bikes, so it started to pop/crackle, and then yesterday.
Now my question is... what would cause that? I rode it today and it didn't do any of that. It ran fine. Any suggestions? I just changed spark plugs a couple/few weeks ago as well.
Thanks for the help fella's.

Was it on acceleration or decel? If it's on decel, check your exhaust flange nuts. I had the same thing on the way home yesterday. It started out just a little and gradually got worse. By time I got home it was horrible. Both nuts on my rear pipe flange were missing. Two new nuts and exhaust seals today and it's running like a champ.

The exhaust flange nuts could be the cause, and while you're at it, check all the exhaust system connections and fittings.
