Hey again, this time I have another problem I'm consulting the grand consortium of Brick wizards. Since I have started my crusade to make my bike stock, since I bought it, I ordered a stock muffler to replace the obnoxious Luftmeister. I replaced the 3 copper crush gaskets, studs, and nuts aswell along with the muffler, headers, and rubber stopper under it. The problem is now, a few things, first the smell. It smells absolutely awful, I smell terrible when I get done with a test ride and it stinks up the garage, my mom hates it and therefore it's first on the list. Second, the bike is slow as hell for the first 5 minutes of riding. It's not until it gets super hot that the throttle wants to be responsive, because when it's cold it's so weak. I assume I need to get fuel trim adjusted? With the Luft, even as it was loud as hell, it was responsive in all ranges and felt great, with the stock muffler I got, the bike is different for the worse. Any help is appreciated as always, and I will try to reply in a timely manner.
NOTE: I have performed the lean drop test and the RPMs do not deviate but maybe 50 rpm in either direction, but no stalling or stumbling. I have indeed tuned up the bike since I got it, Oil, Plugs (I got the right ones with the threaded end and caps), Filter, Fuel Filter, FD and GB Oil, Tires, and of course now, Exhaust.
