Hello,
A little bit of history with my 2009 EC300. As temperatures started to get little higher around here I decided to drop down the needle. As I did it, I went for a test ride and the bike was running fine mid and high rev, but poor bottom and idle. It was idling too high, and if left like that for some seconds it would stall. Started fiddling with the air and idle screws but then I noticed the air filter tube (or whatever it is called) was loose from the carburetor and was sucking air. I put it back in place, but it didn't make a difference. I went back to the "original" settings, and still the bike has no low end power and idles like crazy. I know it's a classic lean situation (and the color of the plug proves it), but I just can find a damn air leak!!! Pilot jet is 45, and I ride mainly between 1500 and 3000 feet altitude (500-1000 meters).
Because of all that, I'm going through a full service - repacking the silencer (noticed excessive spoonge, even at its front end), power valve cleaning, reed checking, carb cleaning, etc.
Now, I disassembled the power valve mechanism (getting the flapper pivot rod was such an odyssey!), but the flapper just wouldn't go out of the exhaust port. Is there a special position it should be in? The tech article says only to remove it. The French site http://translate.google.com/transla...gasons.com/index.php?site=static&staticID=133 also doesn't mention anything peculiar, but the SOB just floats there, going about 1/2" out. I swear it's like it's begging me to smack it really good from the inside...
Help and advice much appreciated.
P.S. If I pull the choke the idle gets better, but then the mid and high end power is messed up.
