Question about the jetting on my KLR
I bought an 06 KLR from a guy who had "rejetted it for high altitude" here in Colorado.
I know he put in a 138 main jet, a supertrapp exhaust, and drilled holes in the airbox.
The bike runs outstanding with lots of power. I just don't like the pipe as it is too loud.
So I put the factory exhaust back on and covered up the holes in the airbox with duct tape.
It seems to run ok, obviously not the grunt it had before but feels like a stock bike.
My understanding is that the factory sent these things out rich. So do you think I need to mess with the jetting or just leave it with the 138?
