What was wrong with this cylinder? (pics) Reply #75 – April 14, 2013, 01:04:58 AM The rattling is coming from the driver side cat. We had that out after dropping a nut down there and I know nothing else fell in there. Perhaps the cat has broken and needs to be replaced. They should be installed up closer to the front without the air pump though...Now that everything is taken care of engine-wise, now I just need to finish up the LED tail lights. The painting is the hardest part, getting an even coat to block all light through the louvers/fins, but not have it too thick in places which won't be durable. It's hard on used lenses. Hopefully I can carefully finish them soon after having sprayed 4 thin coats over them today. I'd like to get the bottom LED conversion complete! The top is done/installed and it's beautiful.
