my dad wants to know how to do the fuel cap vent fix, any suggestions?
Inside remove the fuel cap off the tank (unscrew it)
Then look for a hole thats near the bolt holes. That is overflow/breather and drains away to the long pipe under the tank that dangles near the shock.
Keep that clear or spray air compressor. You will hear air hiss out of the super long overflow pipe.
Check the fuel cap unit by pressing its springs down and see if they come up smoothly. There is no rebuild kit for them. So if its suspicious or packed it. A replacement is advised.
That is also a good question from him 👍
