Muffler Back to Stock... Now What??
So I just replaced my Supertrapp Ids2 slip-on muffler with a 2011 stock muffler. My KLR is a 2006. The bike was running fine with the Supertrapp but I didn't want to deal with the re-packing.
Anyways, I put the stock muffler on. It was running fine. I took it to my mom's house (15 mins away) visited for a bit then on my way back the bike lost power then died. Won't hold an idle for long. I had to keep it at high rpms to get it back to the house.
Gas was coming out of the carb overflow hose.
Spark plug - Oil Fouled
Main Jet - 140
So I replaced it with a 148, doesn't say "Kehin" but it fit.
I also discovered 5 holes in the top of the airbox.
The idle mixture screw plug hadn't been removed so I assume they hadn't touched it.
With this information, I'm wondering how I might be able to get my bike back running great with the Stock back on?? Do I use Gorilla Tape on the airbox holes, replace the spark plug and call it good? I'm also going to to check the float height tonight.
Thank you in advance. Please help.
