Does anyone know of a part number for the O-rings on the bottom of the Air Cleaner Housing that seal to the Throttle Bodies? There doesn't seem to be a part number shown on the NT700 drawings on the Air Cleaner Housing Page or on the Throttle Body page. One of these O-Rings was discovered to be damaged during my 8000 mile Valve Adjust procedure while removed the Air Cleaner Housing. I believe this is the first time the Air Cleaner Housing has been removed, previous owner had from 1700 miles and I don't think he did the 600 mile check. If you have a NT700 Service Manual the O-Ring is shown on the top of page 6-47. Went to the local Honda dealer....no much help there.
The O'ring is close to 2" ID X 1/8" cross section, or 50mm X 3.5mm, not a popular size. I spliced two 1/8" cross section orings to make one that should work fine, but would rather have stock o-ring if possible.
Im pretty good at Honda part numbers, but I couldn't even find a similar model v-twin with similar air cleaner/throttle body setup that showed an o-ring. If I just had the first 5 digits of the part number from any model Honda, I may be able to find a complete part number. I new to v-twins...nothing like those 1960's Honda's.
Hey, the good news is my valves were fine at 8000 miles, no adjustment needed.
Here are 2 pics of the O-ring from the bottom of the Air Cleaning Housing.
