I love my vmax to death, I do, but shit just keeps breaking. Recently, cylinder number 4 went dead, so I replaced the spark plugs, wires, and boots. When I fired it up, it sounded really bad, the right pipe sounded like a flip flop being slammed on the ground repeatedly. The left pipe seemed fine. Not only that, but white smoke was pouring out of the right pipe. So I pulled the plugs, did a compression test on all 4 cylinders, got 60 on both right cylinders, 115 on the left two. Then I did a wet compression test by pouring a tiny bit of oil into each cylinder and compression got better. Immediately, I thought it was the piston rings. Now i'm not to sure. I did an oil change, and added in some "engine life extender" I don't exactly remember the brand. Now, the right pipe doesn't smoke anymore, still flaps but not as badly. It also idles way higher, at about 1500 rpm and rev hangs pretty badly. I turned the idle adjuster all the way clockwise and counter-clockwise, nothing. What's odd, is that it still accelerates just as ferociously as it always did. I wanted to get you guy's opinion before I take it to a shop and pay a couple hundred bucks or so to have it diagnosed.
