If the packing in your silencer has gone to toast and more cruddy and blacker than ME will it cause your bike to run abnormally and even not idle? My bike usually idles fine but I'm not sure what is causing it to stall now. It will idle for about a minute, then you can hear the motor slowly bog and completely shut down unless you give it some gas. I'm not sure if it's the jetting and the warm weather now playing a part in it or perhaps bad gas from sitting around for too long.... or maybe just needs a carb cleaning because it's gummed up. Anyway, I'm trying to eliminate silence packing as perhaps the culprit in this, so I ask, if the packing is in bad enough shape, will it cause the bike to run oddly? I took a look at it and it's in pretty bad shape. BTW it's a Honda CR125 'Super Special Edition' that has an FMF Fatty Pipe & Shorty Silencer. Oh yeah!
