Well, the shop called this afternoon and said the reason for the sudden woes on my bike was a collapsed air filter.
I've never heard of that - I wouldn't think that this little 400cc thumper would have had that much power.
HISTORY: All of a sudden I was fouling out the plug within a few hundred miles and dumping fuel in to the crankcase. My mileage had cratered and my light throttle drivability was jerky at best. Changed the plug and oil/filter the other day. Took it to the shop last Tuesday and they called today saying that the collapsed air filter was causing all the problems.
PRESENT: So, what exactly is a collapsed air filter and what causes it? No matter how clean the air filter is, the way the air intake is (less than 12" from the road ad pointed down) this filter will start to get filthy within a week (less than 100 miles). Also, I replace the plug just before I took it in to the shop and it's already fouled.
So again, what exactly is a collapsed air filter and what causes it? I know most of you don't have any idea how the air intake system is routed on a Burgman 400, but if there's a way to add some hose, etc. to it and reroute it that should help a lot of my problems.
These paper filters can "unofficially" be cleaned several times over their lifetime and at over $50 a piece I can't be replacing one every six months. A K&N is a royal pain to install but I'm going to try one again.
I would have thought that if the filter was plugging that the O2 sensor would have compensated - maybe the software isn't sophisticated enough to do so.
I'll pick the bike up tomorrow and clean the filter again if I can - if not, then I can get by another day or so until the replacement comes in.
I'm also betting I can clean the plug (either the current one or the previous one) - if not, then another one can be bought up the street.
Now, if this doesn't fix the problem - any suggestions on how to handle it with the service department? I was hoping for my hour of diagnostics they would have done a bit more besides ride it a few minutes and hook up their scanner to it.
