Bike is a 2006 ZX-10R. I've taken out the screws in the air box to split it into two halves for cleaning (not just taking the lid off). Putting it back together, I'm noticing some gaps that were previously sealed with some sort of black rubber like material. The gaps aren't anywhere near the screws, so it isn't at matter of being misaligned or needing to be tighter.
Now I'm looking for something to use on the seam to fill in the gap in a few places and also create an airtight seal. I had a go with clear RTV, but it doesn't seem to be bonding well enough to the plastic air box to give me confidence it will last any acceptable amount of time and not break apart and get sucked into the engine. Is there something more acceptable for this sort of thing?
