Hey Kxriders.
I have a 1985 Kx 125 - And the previous owner has a nut and a bolt setup for the top of the chambering cap. I cannot find the part for nothing...

The cap is non-threaded. Can i upgrade my chambering cap to a threaded inlet?
Please Help!!! Any info would be greatly appreciated! My email is Stevenwright91@comcast.net
