I've been reading up how to open up the stock muffler but I hope I didn't go overboard...what I did.
-enlarged the hole in the back half muffler
-enlarged the slit beside the hole
-drilled three holes in the internal baffle
-installed a dual port cover
I left the screens in place.
will this produce some good results? What should I do different? I'm going to get the carb set with a tach later this week. 13,500 rpm correct?
